https://jperairan.unram.ac.id/index.php/JP/article/view/1519
<p>Tilapia in Sidenreng Rappang Regency has the potential to be cultivated, because it is popular in the community. However, there is a problem in tilapia production, namely the high cost of feed. Raw materials for feed are one of the causes of the high price of feed, So an alternative is needed to use local raw materials that are cheap and easy to obtain, namely using broomstick fish meal. This study aims to determine the effect of increasing tilapia production through substitution of fish meal with catfish meal in artificial feed on nutritional quality, growth rate, feed consumption level, and hepatosomatic index. This study was conducted in January - February 2025. Located at the Unhas Education Pond, Bojo District, Barru Regency, South Sulawesi Province. This research used a completely randomized design (CRD) with 5 treatments and 3 replications, so that there were 15 research containers filled with 15 individuals per container weighing 3 grams. The treatments given were treatment A = 100% local flour and 0% broom-sapu fish meal, treatment B = 75% local fish meal and 25% broom-sapu fish meal, treatment C = 50% local flour and 50% broom-sapu fish meal, treatment D = 25% local fish meal, 75% broom-sapu fish meal, treatment E = 0% local fish meal, 100% broom-sapu fish meal. Data were analyzed using a comparison of the mean analysis of variance (ANOVA). Based on the results of the study, the treatment with the best value in the proximate analysis of feed, growth parameters and feed consumption was treatment E with a crude protein value of 32.81%, growth (3.810 ± 0.18a) and feed consumption value (13.23 ± 1.57a). In the Hepatosomatic Index parameter, the treatment with the highest value was treatment D with a value of (0.15 ± 0.00a).</p>Muhammad Anugrah SulaemanSurianti SuriantiDamis Damis

https://jperairan.unram.ac.id/index.php/JP/article/view/1391
<p>Tilapia (<em>Oreochromis niloticus</em>) is a freshwater fish with economic commodity value and an important commodity in the freshwater fish business in Indonesia. Problems often encountered in efforts to increase tilapia cultivation production are the reduction of empty land for cultivation activities and complex water sources in some areas. Land availability and water source supply are two main factors determining fisheries cultivation's success. Aquaponics is an alternative cultivation method that can save land and water use and optimize cultivation waste into plant biomass as a by-product with a selling value. The method used in this research is the Completely Randomized Design (CRD) experimental method, which consists of four treatments and three replications. The treatments used consist of (A) without mixing probiotics (negative control), (B) adding probiotics 5 ml.kg<sup>-1</sup> feed, (C) adding probiotics 7.5 ml.kg<sup>-1</sup> feed, and (D) adding probiotics 10 ml.kg<sup>-1</sup> feed. The test tilapia were cultured in an aquaponic system with lettuce plants for 40 days with a density of 20 fish/80L. Feeding was carried out using the feeding rate (FR) method of 5% of biomass. The results obtained during the study showed that treatment C with a dose of 7.5 ml.kg<sup>-1</sup> of feed produced positive conditions that were significantly different in terms of a specific growth rate of 2.30 ± 0.1%, 100% survival, and feed efficiency of 56.5 ± 1.6%, absolute length was 3.08 ± 0.07 cm and absolute weight was 13.14 ± 1.53 gram</p>Djordan Bembie FauziantakaFittrie Meyllianawaty PratiwyAsep Agus HandakaIrfan Zidni

https://jperairan.unram.ac.id/index.php/JP/article/view/1399
<p>KMN. Bukit Safa is a fleet that uses pelagic purse seine fishing gear with one ship. One of its main catches is the shortfin scad (<em>Decapterus macrosoma</em>). To maintain the quality of the caught fish and prevent damage that could lower its market value, it is important to implement proper handling methods on board the ship. This research was conducted with the aim of describing the physical condition of the fish after being brought on board and determining the freshness quality of the fish after the handling process on the ship. The research was conducted from February 23 to April 5, 2024, on the KMN. Bukit Safa, which is based at the Kendari Oceanic Fishing Port. The data collection method in this study used observation, interviews, and documentation techniques. To assess the freshness of the fish, it refers to the organoleptic evaluation SNI 2729:2021 on fresh fish. The data were analyzed quantitatively with reference to SNI 2346:2015 on sensory testing guidelines for fishery products and then analyzed descriptively. The physical condition of the fish brought onto the ship during the study was intact, lightly damaged, and heavily damaged. Based on the data analysis for the quality assessment results of the flying fish, there were several fish that experienced a decline in quality but were still in a fresh condition. The freshness of the fish is influenced by the quantity of the catch, the handling techniques used on the ship, the amount of ice used during handling, and the duration of the freshness assessment after the fish handling process on the ship.</p>Rakhma Fitria LarasatiYulia Estmirar TanjovI Putu Agus Adnyana

https://jperairan.unram.ac.id/index.php/JP/article/view/1469
<p>Snakehead (<em>Channa striata</em>) is a high-protein fish that is less preferred for direct consumption. Through food diversification, snakehead fish meat can be processed into fish flour and incorporated into various food products, including wet noodles. This study aims to determine the optimal concentration of snakehead fish flour to produce wet noodles with the highest panelist preference. The method used was a laboratory experimental method, involving the preparation of wet noodles with snakehead flour at four different concentrations (0%, 5%, 10%, and 15%) and an evaluation by 25 semi-trained panelists to determine their preferences. The parameters observed included fishmeal yield, panelist preferences, and the chemical composition of wet noodles. The 10% snakehead flour treatment was the most preferred, with the highest alternative value of 8.05, and average scores for appearance (8.12), aroma (5.80), texture (6.68), and taste (7.72). The chemical composition of the 10% treatment included 10% protein content, 33.94% water content, 7.54% ash content, 3,85% fat content, and 44,67% carbohydrate content.</p>Elviana Dian Mustika SariRusky Intan PratamaAulia AndhikawatiIis Rostini

https://jperairan.unram.ac.id/index.php/JP/article/view/1474
<p><em>Recirculating Aquaculture System</em> (RAS) was chosen as an alternative for sustainable and low-impact mangrove crab cultivation. One of the main challenges in using RAS is determining the optimal feeding frequency. Inappropriate feeding can cause slow growth, increased mortality, and decreased water quality. This study aimed to analyze the effect of trash fish feeding frequency on the growth of mangrove crab (<em>Scylla serrata</em>) reared in RAS. The method used is an experimental method with a completely randomized design of 3 treatments and 4 replications. The research treatments tested were the frequency of feeding with FPP 01 once a day at 10 pm; FPP 02 twice a day at 10 pm and 5 pm; FPP 03 three times a day at 10 pm, 8 am and 5 pm. The parameters observed were survival, weight growth, carapace length growth, carapace width growth, specific growth rate and molting rate. The research data were analyzed using analysis of variance at a 95% significance level. The results showed that the frequency of feeding did not significantly affect the growth and survival of mud crabs in RAS. The frequency of feeding once is optimal to achieve maximum growth in mud crab cultivation using the RAS system with a survival rate of 100±0.00%, weight growth of 52.00±21.17 g, carapace length growth of 1.90±0.87 cm, carapace width growth of 1.60±0.70 cm, specific growth rate of 5.04±0.14%/day and molting rate of 67.00±0.58%.</p>Zavira MayzuriAmelia Sriwahyuni LubisEni Kamal

https://jperairan.unram.ac.id/index.php/JP/article/view/1477
<p><em>Papaya leaf extract is known to have various benefits, including the papain enzyme which can function as a protein digester and improve the fish's immune system. The use of natural ingredients such as papaya leaf extract can also reduce dependence on synthetic chemicals, making it safer for human health and the environment. Based on the explanation above, it is necessary to conduct research on the effect of giving different doses of papaya leaf extract on the specific growth rate, feed conversion ratio and also the water quality of African catfish (Clarias gariepinus) seeds. This research was conducted in June - August 2024 at the Fisheries Production Laboratory of the Matauli Fisheries and Marine College. The effect of adding papaya leaf extract to feed with different doses on the specific growth rate, feed conversion ratio and water quality of African catfish (Clarias gariepinus) seeds produced the best results. The best treatment for Specific Growth Rate was in the P1 treatment of 1.405%, Feed Conversion Ratio of 1.411, and water quality in the form of temperature and pH which were in optimal conditions. This dose can be an alternative as a natural ingredient that has benefits to support an environmentally friendly and sustainable catfish (Clarias gariepinus) seed cultivation system.</em></p>Mhd.

https://jperairan.unram.ac.id/index.php/JP/article/view/1484
<p><em>This research utilizes the potential of snakehead fish (Channa striata) rich in albumin (62.9%) and essential nutrients for functional food development. Snakehead fish has superior nutritional value with 25.2% protein, important minerals such as calcium and phosphorus, and essential amino acids that play roles in growth and immune system. The effort to diversify snakehead fish processing into flour and its fortification into velvet bean (Mucuna pruriens) tempeh was carried out to increase nutritional value and consumer acceptance. The research employed an experimental method with 4 treatments of snakehead fish meat flour addition: 0% (TB0), 8.5% (TB1), 9.5% (TB2), and 10.5% (TB3). Parameters tested included organoleptic properties and proximate analysis. Results showed formula TB2 (9.5%) obtained the highest alternative value (6.58) with 39.34% protein content, 13.89% fat, 8.90% moisture, 2.43% ash, and 43.10% carbohydrate. Compared to control, the addition of snakehead fish flour increased protein content by 8.49% and decreased fat content by 5.39%. It can be concluded that the fortification of 9.5% snakehead fish flour produced velvet bean tempeh with the highest organoleptic acceptance and successfully utilized local food ingredients to produce highly nutritious functional food acceptable to consumers.</em></p>Achmad SyauqibikJunianto JuniantoNur FitriantoIis Rostini

<p><strong>A</strong><strong>BSTRACT</strong></p> <p>One of the main limiting factors in the reproduction of snakehead fish (<em>Channa striata</em>) is that the female broodstock fails to spawn, because they cannot complete the final stages of vitellogenesis and ovulation naturally. Therefore, a breakthrough is needed in snakehead fish hatchery to increase the percentage of female broodstock successfully spawning. The aim of this study was to evaluate the effect of providing fermented products combined with probiotic EM4 (Effective Microorganism-4) and noni fruit in feed on the reproductive performance of female broodstock snakehead fish. This research uses non-factorial experimental methods. The design used was a Completely Randomized Design (CRD) with three treatments and three replications, namely treatment A (feed without supplementation of the fermented product with a combination of EM4 probiotics and noni fruit), treatment B (feed with supplementation of the fermented product with a combination of EM4 probiotics and noni fruit at a dose 10%), and treatment C (feed supplemented with fermented products combined with EM4 probiotics and noni fruit at a dose 20%). The results of the research showed that the addition of snakehead female broodstock feed with a fermented product combining EM4 probiotics and noni fruit at a dose of 10% gave the best results, namely an average gonad maturity index (IKG) value of 2.56%, relative fecundity of 3562 eggs per female broodstock, fertilization rate 87.33%, hatching rate 91.67%, and egg yolk absorption time 78 hours, and prolarva survival rate 98.67%.</p> <p> </p> <p>Keywords: female broodstock of <em>Channa striata</em>, noni fruit, reproduction performance, probiotic EM4.</p>Tuti Feberiani TelaumbanuaRicky DjauhariNoor Syarifuddin Yusuf

https://jperairan.unram.ac.id/index.php/JP/article/view/1508
<p><em>Macrozoobenthos have played an important role in coastal ecosystems, especially in beaches and mangrove areas, as indicators of environmental health and as important components of the food chain. However, the presence of human activities such as industrial waste, households, fisheries and agriculture could affect the abundance of macrozoobenthos in coastal areas. The purpose of this study was to assess and analyze the type, abundance, diversity, uniformity and dominance of macrozoobenthos and sediment substrate conditions in the beach and mangrove areas in Tanjung Limau village, Kutai Kartanegara Regency. This research was conducted from December to March 2024. This research method uses descriptive methods with sampling techniques using purposive random sampling. Macrozobenthos sampling sites were divided into 2 (two) stations. Station 1 was located at beach area, while station 2 was located in the mangrove ecosystem area. The results showed that the abundance of macrozoobenthos in the mangrove area (13 species) was higher compared to the beach (18 species), with groups of snails and bivalves. Abundance at station 1 (43.3 ind/m²) was lower than at station 2 (58.0 ind/m²). The diversity index value at station 1 (2.16) and station 2 (2.57) was classified as moderate. Uniformity at stations 1 and 2 was 0.84 and 0.87 (high category), respectively. Then the dominance index values found at stations 1 and 2 were 0.17 and 0.10 (non-dominant category), respectively. The sediment texture in the coastal area of Tanjung Limau at both stations 1 and 2 is a clayey loam, which is one of the main causes of the differences in macrozoobenthos abundance.</em></p>Dorsen Hotma Tua SimanihurukMohammad Sumiran PaputunganIrwan Ramadhan Ritonga

https://jperairan.unram.ac.id/index.php/JP/article/view/1516
<p>Inefficient feeding in vannamei shrimp (Litopenaeus vannamei) cultivation has a negative impact on growth and water quality. The purpose of this study was to determine the effectiveness of index system feeding on growth rate and water quality in vannamei shrimp (L. vannamei) cultivation. The research method used was descriptive, the data were analyzed using the t-test statistical test. The parameters tested in this study were growth parameters including Average Body Weight (ABW), Average Daily Growth (ADG), Feed Conversion Ratio (FCR), and Survival Rate (SR). Water quality parameters include temperature, pH, Dissolved Oxygen (DO), salinity, ammonia, nitrite, nitrate, and Total Organic Matter (TOM). The results showed that there was a significant difference between the feeding index system and the anco check system. The index system is more effective in increasing the growth rate and the Feed Conversion Ratio (FCR) and Survival Rate (SR) results are obtained according to the optimum value. In the index system the average Average Body Weight (ABW) is 14.24 ± 0.68, the average Daily Growth (ADG) is 0.43 ± 0.02, the average Feed Conversion Ratio (FCR) is 1.06 ± 0.04, and the average survivak rate (SR) is 70.75 ± 5.56%. Whereas in the anco check system the average Average Body Weight (ABW) is 12.1 ± 1.13, the average Daily Growth (ADG) is 0.35 ± 0.04, the average Feed Conversion Ratio (FCR) is 1.18 ± 0.07 and the average survival rate (SR) is 59.25 ± 5.12%. Water quality during maintenance obtained optimum results according to the optimum standard of water quality for vannamei shrimp (L. vannamei) cultivation. Feeding the index system gives better results for the growth rate in vannamei shrimp farming, so that the feed given is more effective and efficient.</p>Hany HandajaniBrilian Amanat TaqwaHariyadi Hariyadi

https://jperairan.unram.ac.id/index.php/JP/article/view/1522
<p><em>Kiluan Bay is one of the marine conservation areas in Tanggamus Regency, Province of Lampung through which dolphins migrate. This research aims to analyze the relationship between the distribution of sea surface temperature and chlorophyll with the appearance of dolphins in Kiluan Bay. This research uses an exploratory survey method. The research results show that the highest appearance of dolphins was in the Transition Season I, around 117 in the temperature range of 29,44-29,88°C with a chlorophyll concentration of 0,120-0,184 mg/m³ and the lowest in the West Season was around 31 in the temperature range of 28,56-29,34°C with a chlorophyll concentration of 0,096-0,134 mg/m³. The appearance of dolphins is more strongly related to sea surface temperature than to chlorophyll concentration because dolphins do not eat phytoplankton directly where there is a time lag where increasing the chlorophyll concentration value does not immediately have an impact on increasing the intensity value of dolphin emergence, but requires some predation time<strong>.</strong></em></p>Anma Hari KusumaEko EfendiHenky MayaguesIndra Gumay YudhaQadar Hasani

https://jperairan.unram.ac.id/index.php/JP/article/view/1525
<p>Blue Swimming Crab (<em>Portunus pelagicus</em>) has a calcium content in the crab shell of 19.97%, which has the potential to be used as an additional ingredient in snack bar products. This study aims to determine the concentration of blue swimming crab shell flour to produce the snack bars that panelists prefer. The study was conducted from October to December 2024 at the Fisheries Product Processing Laboratory, Faculty of Fisheries and Marine Sciences, Padjadjaran University, Nutrition Laboratory, Faculty of Animal Husbandry, Padjadjaran University, and Saraswati Indo Genetech Laboratory, Bogor. The research is classified as experimental research with a Completely Randomized Design method, namely making snack bars with the addition of crab shell flour with four treatments (0%, 1.5%, 2.5%, and 3.5%) and 25 semi-trained panelists as replications to determine the level of panelist preference for snack bars. Data analysis was done using the Friedman and Bayes tests to determine the best treatment. The parameters observed were the organoleptic and chemical content of the snack bar<em>.</em> The results showed that the most preferred addition of crab shell flour was the 2.5% treatment because it had the most significant alternative value of 8.61 with an average appearance of 8.0, aroma of 8.3, texture of 7.4, and taste of 7.9. The chemical characteristics produced by this treatment: 1.75% water content, 2.85% ash content, 9.62% protein content, 12.93% fat content, 72.85% carbohydrate content, and 436.48 mg/100 g calcium content</p>Atik Nur LatifahEmma RochimaRusky Intan Pratama Iis Rostini

https://jperairan.unram.ac.id/index.php/JP/article/view/1533
<p>Protein is an essential macronutrient component in fulfilling human nutritional needs. Fish as<br />a source of animal protein has unique nutritional characteristics that make it a potential high-<br />quality food source. This study aims to review the advantages of fish protein compared to non-<br />fish protein through a systematic review method. Data collection used the Google Chrome<br />search engine with keywords fish protein, advantages of fish protein, and non-fish protein on<br />30 literature published from 2014-2025. Furthermore, the data were analyzed descriptively<br />comparative. The review results show that fish protein content (19.9-58.8%) is higher than non-<br />fish protein (1.59-19.76%), with tilapia and snakehead fish leading (58.8% and 53.17%). The<br />amino acid profile of fish is also superior, indicated by the presence of tryptophan in snakehead<br />fish (0.13%) and striped snakehead (0.14%) which is not detected in non-fish sources. Seahorse<br />shows significant advantages in arginine content (3.55%), valine (3.38%), leucine (4.22%), and<br />lysine (6.8%). It can be concluded that fish protein is superior to non-fish protein, both in terms<br />of quantity and quality, making it an excellent source of animal protein for fulfilling human<br />nutritional needs.<br />Key words: Amino Acid, Animal Protein, Fish, Nutritional Composition, Protein</p>Junianto JuniantoAchmad Syauqibik

https://jperairan.unram.ac.id/index.php/JP/article/view/1527
<p>The condition of the nest greatly determines the success of turtle egg hatching. The success of turtle egg hatching, both naturally and artificially, is influenced by several factors such as the location of the nest, the depth of the nest, vegetation conditions, environmental temperature, humidity and the surrounding environment. This study aims to see the effect of shade on the length of the incubation period and the success of green turtle egg hatching in semi-natural nests. This study was conducted at Pangumbahan Nesting Beach, Sukabumi. This study used an experimental method with the treatment of semi-natural nests placed in exposed areas and shaded areas with different depths, namely 68 (control), 30, 50, 70 and 90 cm. Measurements and observations of environmental conditions were carried out during the incubation period. Observations of hatching of hatchlings began on the 55th day of incubation and the dismantling of the entire nest was carried out on the 68th day of incubation. The results showed that in exposed areas there was no significant difference given the level of treatment on the length of the incubation period, while in sheltered or protected areas there was at least one difference in the level of treatment that had a different effect on the length of the incubation period. The fastest incubation period in exposed areas was at a depth of 30 cm and in sheltered areas was at a depth of 90 cm.</p> <p>Key words: <em>incubation period, the green turtle, the success of hatching.</em></p> <p> </p>Yusyam LeniNeviaty Putri ZamaniNyoman Metta Nyanakumara NatihAinun Rohmawati BaretaRiris Roiska

https://jperairan.unram.ac.id/index.php/JP/article/view/1231
<p><em>Sanitizing the water environment in vanamei shrimp (Litopenaeus vannamei) ponds will increase shrimp growth and improve the economy. Obstacles in aquaculture are the decreasing quality of production results and decreasing water quality. A biofilter is needed as a phytoremediation to reduce the high ammonia content from leftover feed and feces. The main component of this technology is seaweed (Gracilaria sp.) as a living technology that provides services in overcoming environmental problems. Therefore, phytoremediation technology can be used to manage nutrient and water dynamics; This can result in significant improvements in water quality as well as the restoration of degraded ecosystems. The aim of the research was to determine the effect of differences in density of Gracilaria sp. as a phytoremedian in the cultivation system to reduce the ammonia (NH3) content of shrimp pond wastewater in Batu Lotong, South Larompong District, Luwu Regency, South Sulawesi. The research used a completely randomized design (CRD) with 4 treatments and 3 repetitions. The results of measurements in the experiment showed that the highest ammonia (NH3) content in treatment D (0 g seaweed) ranged from 0.0074 mg/L - 0.0335 mg/L and the lowest in treatment A (100 g seaweed) ranged from 0.0032 mg/L-0.0335 mg/L. Specific growth rate of daily weight of seaweed Gracilaria sp. in treatment A (2.95%) per day, B (2.59%) per day, C (1.81%) per day, and D (0%) control / not given seaweed. This shows that the difference in density of the seaweed Gracilaria sp. as a phytomedian in the cultivation system, it has an effect on reducing the ammonia (NH3) content and the daily specific growth rate of the seaweed Gracilaria sp. The Anova statistical test shows that the seaweed Gracilaria sp has a real influence on reducing the ammonia (NH3) content in pond water (F.hit > f table 5%).</em></p>Patahiruddin PatahiruddinAndi Mi’rajusysyakur MuchlisSiswati SiswatiM.

https://jperairan.unram.ac.id/index.php/JP/article/view/1401
<p>Vannamei shrimp (<em>Litopenaeus vannamei</em>) is a primary aquaculture commodity with an export contribution of up to 85%. However, its production faces challenges due to disease outbreaks, particularly White Spot Syndrome Virus (WSSV). This study aimed to detect the presence of WSSV in post-larvae of vannamei shrimp using the Nested-PCR method in three different hatcheries. The methodology included sample preparation, DNA extraction, DNA amplification through Nested-PCR, electrophoresis, and DNA visualization. The results showed that in the first week of testing, all samples tested negative for WSSV, as no DNA bands appeared at 941bp. However, in the second week, one sample (C5) tested positive for WSSV, indicated by the presence of a DNA band at 941bp, while the other samples remained negative. The prevalence of WSSV infection in this study reached 16.67%. The DNA concentration ranged from 94.5 ng/µL to 166.5 ng/µL, with a purity level between 1.72 and 1.86. These findings suggest that the Nested-PCR method is effective in detecting WSSV presence in vannamei shrimp, providing reliable detection rates.</p>Nurul FitriaRahmi RahmiMuhamad Ikbal

https://jperairan.unram.ac.id/index.php/JP/article/view/1496
<p><span style="font-weight: 400;">Social media marketing strategies have become a solution to enhance business competitiveness, particularly for entrepreneurs in the fisheries sector. However, intense competition and low brand awareness of new seafood menu offerings pose challenges for Foremore Resto & Cafe. This study aims to analyze the influence of social media marketing, brand awareness, and purchase intention on purchasing decisions for seafood products at Foremore Resto & Cafe. Data on consumer behavior were collected from 143 respondents using a questionnaire. The data analysis techniques employed include Structural Equation Modeling Partial Least Squares (SEM-PLS) using WarpPLS version 8.0 and quantitative descriptive analysis. The findings indicate that social media marketing and brand awareness play a crucial role in increasing consumers' purchase intention toward seafood products at Foremore Resto & Cafe. Brand awareness directly contributes to enhancing purchasing decisions, whereas social media marketing does not show a direct influence on purchasing decisions. Thus, optimizing social media marketing and brand awareness are key factors in fostering an effective purchase intention that leads to increased purchasing decisions for seafood products at Foremore Resto & Cafe.</span></p>Zainal AbidinYeremia Neuville Hamonangan

https://jperairan.unram.ac.id/index.php/JP/article/view/1500
<p>Whiteleg shrimp are superior in aquaculture due to their high survival rates in intensive cultivation systems, but the use of artificial feed increases aquatic organic matter, reducing dissolved oxygen and causing ecosystem instability. This oxygen depletion affects the survival, growth, and average daily growth (ADG) of the shrimp. Therefore, this study will present data on the correlation between Total Organic Matter (TOM) and the N/P ratio as the end product of the decomposition of organic matter on ADG vaname shrimp body weight gain from intensive shrimp ponds in Banyuwangi, East Java. Data sampling was carried out in 11 intensive rearing ponds at the age of 20 – 60 days of shrimp culture. Data correlation will be analyzed by correlation test using SPSS. The TOM obtained was in the range of 60.67 – 69.52 mg/l. The N/P ratio value obtained is 1.25 – 25.33. The ADG value obtained is 0.15 – 0.59 grams/day. The correlation between TOM and ADG shows a correlation coefficient of 0.468 which states that there is a positive correlation with a moderate level of correlation. The correlation between the N/P ratio and ADG shows a correlation coefficient of 0.066 which states that the results are negative or there is no correlation.</p>Daruti Dinda NindarwiAyu Rizky AgustinNina Nurmalia Dewi

https://jperairan.unram.ac.id/index.php/JP/article/view/1511
<p><em>The riverine ecosystems traversing Banyumas Regency through the Serayu Watershed (DAS Serayu) serve as strategic freshwater resource zones, supporting both ecological functions and local livelihoods through economically valuable fish species. However, anthropogenic pressures such as domestic waste pollution, land-use conversion, overfishing, and the use of destructive fishing methods have led to significant ecological degradation. This study aims to: (1) identify key issues in the management of riverine fish resources in Banyumas as common property resources, and (2) explore community-based local wisdom practices implemented for sustainable fisheries conservation. Conducted in February 2025 at the Pokmaswas Lestari Kaliku post in Rawalo Subdistrict, this research employed a qualitative descriptive approach, utilizing field observations, in-depth interviews, and FGDs with 38 respondents drawn from key institutions, including the Provincial Marine and Fisheries Office, Banyumas Fisheries and Livestock Office, local fishery extension workers, the Rekam Jejak Nusantara NGO, and 9 active community monitoring groups (Pokmaswas). Findings reveal that Pokmaswas have adopted various forms of traditional ecological knowledge as management instruments, including: (1) prohibition of hazardous fishing gear (poison and electric shock), (2) establishment of core conservation zones (fish sanctuaries), (3) periodic restocking of indigenous fish species, (4) enforcement patrols against illegal and destructive fishing practices, and (5) public education and outreach initiatives on river ecosystem conservation. These practices demonstrate not only ecological effectiveness but also the critical role of community participation in achieving sustainable fisheries management. In conclusion, local wisdom-based approaches prove to be strategic and effective in addressing complex aquatic resource management challenges, offering an integrated pathway between conservation imperatives and the socio-economic needs of riverside communities.</em></p>I Gede Suweda Anggana PuteraTaufik Budhi PramonoTeuku JunaidiSahda SalsabilaPhilipus Uli Basa HutabaratAbdul Malik FirdausMahardhika Nur Permatasari

https://jperairan.unram.ac.id/index.php/JP/article/view/1534
<p><em>One of the nutrients that play an important role for fish growth is protein, one of which is in the formation of body tissues. The amount and quality of protein in fish feed affects growth performance, feed utilization, water quality and of course the price of the feed itself. Excessive feed protein or whose quality does not meet the needs will be excreted as nitrogen waste, especially in the form of ammonia. This study aimed to reduce protein consumption in tilapia (Oreochromis niloticus) diets through selenomethionine supplementation. The test feed was designed using two different protein concentrations: 26% and 30%. Selenomethionine supplementation levels were 0 mg/kg (control) for 30% feed protein, and 3 mg/kg and 6 mg/kg Se for 26% feed protein. This study used a completely randomized design (CRD) with three treatments and three replicates. Tilapia with an average initial weight of 8.05 ± 0.25 g were reared in an aquarium measuring 100×50×50 cm³ with a stocking density of 15 fish per aquarium. The fish were reared for 60 days and fed three times a day until full. The results showed that supplementation of 3 mg/kg Selenomethionine to 26% feed protein was better than either the control or 6 mg/kg Se supplementation. Supplementation of 3 mg/kg Se to 26% feed protein level significantly increased feed intake (FI), final biomass weight (Bt), feed conversion ratio (FCR), feed efficiency (FE), protein retention (PR), and daily growth rate (DGR) in tilapia. A 100% survival rate was recorded in all treatment groups.</em></p>Christian Ernsz PattipeilohyBethsy Jane PattiasinaJoice Welly LoupattyChrisoetanto Patrick Pattirane

<p>Sardine fish oil, which is mostly considered useless, is actually very beneficial because it<br />contains various omega-3 fatty acids, especially EPA and DHA so that fish oil is made into an<br />emulsion product. Emulsion is a two-phase system in which small droplets of one liquid are<br />dispersed into another liquid. The purpose of this study was to determine the characteristics of<br />the best emulsion formula for 30 days of storage. The methods in this study include the stage<br />of determining the emulsion formula, and the emulsion testing stage. In making the emulsion<br />formula, the types of emulsifiers used were Carboxymethyl Cellulose (CMC) and lecithin with<br />a ratio of 1: 1; 1: 2; 3: 1; and 3: 2. The tests carried out included viscosity, pH, and percent<br />stability. The results showed that the highest viscosity, pH, and percent stability tests during 30<br />days of storage were in formula 3: 1 and the lowest in formula 1: 2. During 30 days of storage,<br />there was a decrease in the viscosity, pH, and emulsion stability values for all formulas. This<br />finding shows that the best emulsion formula uses CMC and lecithin emulsifiers, namely 3:1.<br />Thus, this study shows that sardine fish oil emulsion has the potential to be developed into an<br />emulsion product using the existing formula</p>Kristina Haryati

https://jperairan.unram.ac.id/index.php/JP/article/view/1546
<p><em>The main factor in determining the power of a ship's main engine is the ship's resistance resulting from the shape of the ship's hull. Calculation of ship resistance can be done using software, namely Maxsurf Resistance, which can simulate the shape of a ship's hull under water. This research aims to determine the total resistance of a purse seine fishing vessel and the power required to move a 30 GT vessel. The design made from this ship model is then analyze to calculate the ship's resistance a nd the required engine power. The ship resistance calculation method uses the Holtrop method. This method is used because the hull of a 30 GT ship is a V-shaped model. From the results of the discussion, it is concluded that ship resistance can be seen from several speed variations produced by looking at the service speed of 30 GT fishing boats in the Takalar Regency area. From this research, the resistance value for speeds of 0-6 knots resulted in a resistance value of 1.4 kN and engine power of 5,861 hp. Then there is a significant need for engine power or power which occurs from a speed of 7 knots to 10 knots because the value of the ship's resistance continues to increase in line with the speed of the ship. At the maximum speed of a 30 GT purse seine fishing vessel of 10 knots, the total resistance of the vessel is 7.4 kN and the engine power required is 50.572 H.</em></p>Andi Ana Humaerah AmranMukhlisa A.

2025-06-202025-06-201531422143210.29303/jp.v15i3.1549VANAME SHRIMP CULTURE AT VARIOUS PRODUCTION SCALES: TECHNICAL AND ECONOMIC REVIEW (LITERATURE STUDY)
https://jperairan.unram.ac.id/index.php/JP/article/view/1550
<p>Vaname shrimp (<em>Litopenaeus vannamei</em>) cultivation is growing rapidly in Indonesia and has various production scales, from traditional to super-intensive. This study examines the technical and economic differences of each production scale based on literature studies. Technically, the traditional scale still relies on natural environmental conditions with a stocking density of 5–9 shrimp/m<sup>2</sup> and a productivity of 0.1–0.5 tons/ha/period. The traditional-plus scale is a development of the traditional scale with several improvements in technical aspects such as pond bottom soil processing, additional feeding, and simple water quality management with a stocking density of 10–49 shrimp/m<sup>2</sup> and a productivity of 0.7–1.5 tons/ha/period. The semi-intensive scale begins to implement better aeration and water quality management, increasing the stocking density to 50–79 shrimp/m<sup>2</sup> with a productivity of 4–8 tons/ha/period. At intensive and super-intensive scales, the use of technologies such as biofloc systems, Recirculating Aquaculture Systems (RAS), and Internet of Things (IoT) allows for higher stocking densities (80-150 shrimp/m2 and 250-400 shrimp/m<sup>2</sup>) with productivity reaching 15-20 tons/ha/period and 100-150 tons/ha/period. Economically, a more intensive production scale shows greater benefits. The traditional scale has an Internal Rate of Return (IRR) of 10-20% with a payback period of 3-5 years, while the semi-intensive and intensive scales have an IRR of 20-50% with a shorter payback period (1.5-3 years). The super-intensive scale offers the highest benefits with an IRR> 50%, a Net Present Value (NPV) of billions of rupiah, and a payback period of less than 1.5 years. However, intensive and super-intensive scales require large initial capital and more complex management systems, especially in terms of water quality and biosecurity. The results of this study indicate that increasing the scale of production can increase efficiency and profits, but also carries higher risks. Therefore, the selection of production scales must consider technical readiness, financial resources, and good risk management. The application of technologies such as biofloc, RAS, and IoT has the potential to increase the efficiency and sustainability of whiteleg shrimp cultivation. Support from the government and stakeholders is needed to increase the competitiveness of the aquaculture industry through policies that support innovation and sustainability.</p>Ayi YustiatiIskandar Kanna

https://jperairan.unram.ac.id/index.php/JP/article/view/1567
<p>Intensive cultivation of whiteleg shrimp (Litopenaeus vannamei) is now being developed in<br />the aquaculture industry in Indonesia. Efforts to increase the success of whiteleg shrimp<br />cultivation continue made by business actors including BPBAP Ujung Batee. This study aims<br />to analyze the growth rate of whiteleg shrimp intensively cultivated in HDPE and concrete<br />round pond media at BPBAP Ujung Batee. The results of this study can be used as information<br />and references regarding the selection of the right container for intensive whiteleg shrimp<br />cultivation. The study was conducted from June to August 2024. The method in this study was<br />a survey method, where data collection was carried out through direct observation in the field.<br />The parameters observed in this study were Mean Body Weight (MBW), Average Daily<br />Growth (ADG), biomass, survival rate (SR), and feed conversion ratio (FCR). In addition,<br />measurements of water quality parameters were also carried out in the form of temperature,<br />pH, Dissolved Oxygen (DO), salinity, ammonia, alkalinity, nitrite, nitrate, and phosphate. The<br />results of the study showed that the MBW, ADG, Biomass, and SR values of vaname shrimp<br />cultivated in concrete pond media were higher than those in HDPE ponds. The results also<br />showed that the FCR value in concrete ponds (1.4) was lower than the FCR in HDPE ponds<br />(1.5). This means that the FCR of concrete ponds is better than the FCR of HDPE ponds. Water<br />quality parameters showed different results between HDPE ponds and concrete ponds. In<br />HDPE ponds, the water quality parameters that were in the optimal range were pH, DO, and<br />phosphate, while in concrete ponds they were temperature, DO, and phosphate.</p>Yasal YasalFitria RahmayantiMuhammad MuhammadCitra Dina FebrinaSufal DiansyahAgusriati MuliyanaMunandar Munandar

https://jperairan.unram.ac.id/index.php/JP/article/view/1571
<p>Increasing the protein content in Cork Egg Cake can be done by adding tilapia meat flour. This study aims to determine the best percentage of tilapia meat flour addition in making cork egg cake to produce the most preferred product and determine the proximate composition or nutritional profile of the most preferred cork egg cake product. The method used is an experimental method, namely making cork egg cake with different levels of tilapia meat flour addition, consisting of four treatments (0%; 7.5%; 10%; and 12.5%) with 20 semi-trained panelists as replicates to determine the level of panelist preference for cork egg cake. The parameters observed were hedonic test and chemical test. The most preferred addition of tilapia meat flour to the cork egg cake was the 10% treatment with an average value of appearance 8.4; texture 7.8; aroma 7.8; taste 8.1. The resulting proximate test is 3.90% moisture content; 1.56% ash content; 8.52% protein content; 26.21% fat content; and 59.81% carbohydrate content.</p> <p>Key words: Fish Meat Flour, Cork Egg Cake, Favorability, Proximate Test</p>Diyah Ayu AnggreiniJunianto Junianto Rita RostikaIis Rostini

https://jperairan.unram.ac.id/index.php/JP/article/view/1596
<p>The purpose of this study was to evaluate the effectiveness of legume-based prebiotics in milkfish feed, with the hope of increasing growth rate, survival rate, and feed efficiency. The study was conducted using five feed treatments containing soybean flour, peanuts, green beans, red beans, and control. Feed was given at a percentage of 5% of fish biomass per day for 60 days. The results showed that feed containing red beans (Feed D) gave the best results, with a survival rate of 77.777% and the highest specific growth rate of 12.937%. However, the feed conversion ratio was not significant. Feeding containing red beans is thought to improve the performance of fish digestive microflora, contribute to improved health and feed digestibility, and support faster growth. However, although increased survival and growth were achieved, feed utilization efficiency (FCR) still needs to be improved. This study shows that red bean-based feed has the potential to increase milkfish cultivation results sustainably, but feed management and environmental factors are also very important to support cultivation efficiency.</p>Wahyudi WahyudiSiti AslamyahSurianti Surianti

https://jperairan.unram.ac.id/index.php/JP/article/view/1597
<p>Research on fermented feed based on green coconut water combined with molasses and EM4 in the maintenance of tilapia (Oreochromis niloticus) fry in flooded soil ponds has not been conducted until now. Therefore, research using fermented feed needs to be conducted to obtain the right usage technique. This study aims to determine the effective dose of coconut water to improve the growth performance of tilapia fry maintained in soil ponds. This study used a completely randomized design (CRD) with four treatments and three replications. The treatments given in this study consisted of treatment A (Treatment without giving green coconut water, commercial pellet feed 1 kg + 200 mL boiled water + 20 mL molasses + 10 mL EM4 probiotic), B (Treatment commercial pellet feed 1 kg + 150 mL boiled water + 50 mL coconut water + 20 mL molasses + 10 mL EM4 probiotic), C (Treatment commercial pellet feed 1 kg + 100 mL boiled water + 100 mL coconut water + 20 mL molasses + 10 mL EM4 probiotic), and D (Treatment commercial pellet feed 1 kg + 200 mL coconut water + 20 mL molasses + 10 mL EM4 probiotic). Tilapia seeds measuring 2.66-3.06 g were randomly spread into 12 hapa nets measuring 1x1x1 m3, which were installed in an earthen pond with a stocking number of 30 fish/hapa net. The test fish were kept for 28 days and given test feed with a frequency of 1 time/day. The research parameters consisted of harvest biomass (Bt), daily growth rate (DGR), feed conversion ratio (FCR), feed efficiency (EP), and survival rate (SVR). Providing fermented feed based on green coconut water with the lowest and highest doses did not provide optimum results on the growth of catfish. Optimum results were obtained in treatment B.</p> <p> </p>Markhamah MarkhamahRicky DjauhariMuhamad Noor Yasin

https://jperairan.unram.ac.id/index.php/JP/article/view/1507
<p><em>Chanos chanos is classified as a type of cultured fish with great economic value because it plays an important role in meeting the nutritional needs of the community and contributes in improving the welfare of life. Giving probiotics is one way that can be used to overcome environmental pollution. Probiotics themselves are living microorganisms that function to maintain the stability of the digestive system in the intestine. Molasses acts as a source of nutrients for probiotic bacteria and is expected to support the increase in the effectiveness of its population as bioremediation agents can be more optimal. This study aims to evaluate the effect of the addition of probiotics combined with molasses in feed on the growth and survival rate of milkfish (Chanos chanos). This research was conducted from October 10 to December 7, 2024 at Tadang Palie, Kec. Cempa. Pinrang Regency, South Sulawesi with a duration of 60 days. This research was conducted using a completely randomized design (CRD), which involved four different treatments and each treatment was repeated three times. The results showed that the effect of probiotics added to molasses in feed had a significant effect on the growth of absolute weight, specific, absolute length of milkfish. For absolute weight growth, the highest value was in treatment B (7.42 grams), the highest value of specific weight was in treatment B (9.86), the highest value of absolute length was in treatment B (9.4 cm), while survival and FCR had no significant effect on milkfish. The highest survival rate was found in treatment A (87%), and the best FCR value in treatment B (3.08).</em></p>Fahad Bin Muhammad Nur WakkaIlmiah IlmiahAndi Hamdillah

https://jperairan.unram.ac.id/index.php/JP/article/view/1520
<p><em>The application of local probiotics in commercial feed not only contributes to aquaculture efficiency but also opens up opportunities for utilizing inexpensive and easily accessible local materials as alternative environmentally friendly feed additives. Biologically, probiotics work by enhancing the balance of intestinal microflora, improving nutrient absorption, and strengthening the fish's immune system against environmental stress and pathogenic infections. Through this mechanism, the inclusion of local probiotics in feed can be an effective approach to naturally and sustainably enhance the physiological performance of fish fry. This study aimed to determine the effect of adding locally-sourced probiotics to commercial feed on the growth and survival of Siamese Pangasius (Pangasianodon hypophthalmus) fry. The probiotics were formulated using local ingredients such as banana fronds, turmeric, fine rice bran, yeast, molasses, and Yakult, and were applied to commercial feed at various concentrations. The research was conducted experimentally using a Completely Randomized Design (CRD) with four treatments and three replications: P0 (control, no probiotics), P1 (10 mL probiotics/kg feed), P2 (20 mL/kg feed), and P3 (30 mL/kg feed). Observed parameters included growth, feed conversion ratio (FCR), and survival rate (SR). The results showed that treatment P2 yielded the best outcomes, with the highest growth rate, lowest FCR, and significantly higher survival rate compared to the control. In conclusion, enrichment of commercial feed with local probiotics at a dosage of 20 mL/kg significantly improved the growth performance and survival of Siamese Pangasius fry (p<0.05).</em></p>Anne RumondangMhd Aidil HudaNabilah Hanun Panggabean

<p>Online applications are something that currently cannot be separated from people's lives, especially urban communities. The opportunity to utilize online applications is also applied in food sales based on the use of online applications, especially for sellers in the category of Micro, Small and Medium Enterprises (MSMEs). Activities that utilize online applications are called Electronic Commerce (E-Commerce) where physical contact is not required between sellers and buyers. Online applications are one of the things that can support economic progress, but the use of online applications for sales is still limited depending on the area, areas with poor internet conditions usually rarely use online applications for sales. The purpose of this study was to determine how much the marketing of fishery products (Pecel lele) using online applications along the Jatinangor highway which is an area with a high percentage of students and high potential for internet use. The conclusion of this study shows that most of the pecel lele stalls along Jalan Raya Jatinangor have used online applications for sales and fifty percent of pecel lele stalls stated that turnover from using online applications tends to be higher than conventional sales. The conclusion of this study is that in 12 catfish pecel stalls located along the Jatinangor highway, 75% of all stalls have online applications for sales and 25% do not have online applications for sales. In the turnover obtained, 6 out of 12 catfish pecel stalls get higher turnover profits, 3 out of 12 catfish pecel stalls have decreasing turnover profits, the remaining 3 stalls that do not use online applications do not experience changes in turnover profits, namely sales do not increase or decrease.</p>Kekey SakiraIwang GumilarAlfina AlfinaRoffi Grandiosa Herman Ine Maulina

https://jperairan.unram.ac.id/index.php/JP/article/view/1447
<p><em>Kappaphycus alvarezii seaweed produces carrageenan; its growth and development are highly dependent on the quality of the waters and nutrients such as nitrate, phosphate, and potassium. The planting method that cultivators often carry out is to take it directly from the seaweed that is being harvested. This pattern makes the growth of seaweed less than optimal. One solution is to fertilize. One type of fertilizer that can be used is natural fertilizer, such as kasgot fertilizer. This study aims to determine the combination of soaking time and concentration of kasgot fertilizer that effectively increases the growth and carrageenan content of Kappaphycus alvarezii. This research method uses the treatment of the duration of kasgot fertilizer immersion for 2 hours, 4 hours, 6 hours and without immersion (control) and the concentration of kasgot fertilizer of 2 grams, 4 grams, 6 grams, and without kasgot fertilizer (control), repeated 3 times. The results show that the kasgot fertilizer immersion treatment can increase weight, growth rate, and carrageenan value. The higher the dose given, the higher the weight, growth rate, and carrageenan value, although in statistical tests, it was found that the immersion treatment did not significantly affect weight or growth rate. Water quality during the study (temperature, salinity, pH, and depth) was still within the standards for cultivating K. alvarezii seaweed. Further research is needed on using kasgot fertilizer in cultivating other types of seaweed or using different doses.</em></p>Ardi Eko MulyawanAndi MegawatiFrida Alifia

https://jperairan.unram.ac.id/index.php/JP/article/view/1560
<p>One of the biodiversity that Indonesia has and should be proud of is the diversity of freshwater ornamental fish species, one of which is koi kohaku fish (Cyprinus carpio). The purpose of this study was to determine the effect of color in telang flower extract to improve the color quality of koi kohaku fish and to determine the best dose of telang flower extract in improving the color of koi fish. This study used 4 different treatments, namely A (10%) bayang flower extract, B (15%) bayang flower extract, C (20%) bayang flower extract, and D (control). The parameters observed were the brightness of fish color, final weight, length growth, SR, and water quality, which will be analyzed using ANOVA. Measuring fish color using a modified toca color finder (M-TCF) tool where this tool has a color column column marked with a score value from 1 - 60. The results of this study indicate that the addition of telang flower extract to commercial feed affects the color quality of koi kohaku fish. The quality of color severity in Kohaku koi fish is highest in treatment C (20%) with a score value of 35 on fish color, for treatment D (control), B (15%), and A (10) each has a score value of 32, 34, 33 on fish color. Mixing bayang flower extract into commercial feed can improve the color of koi kohaku fish, the best color improvement was found in the treatment of adding 20% bayang flower extract.</p>Hany HandajaniDoddy AriantoAnis Zubaidah

https://jperairan.unram.ac.id/index.php/JP/article/view/1627
<p>This study aims to analyze the effect of the addition and optimal dose of probiotics on the growth performance and health of snakehead fish (channa striata) seeds in the budikdamber system. The budikdamber system is an innovation in fisheries cultivation in limited land that is easy to apply at home by the community at an affordable cost. The study was conducted using a completely randomized design (CRD) consisting of 4 treatments of probiotic doses and a control without probiotics, with each treatment repeated three times. The treatments used were (A) without the addition of probiotics (control), (B) the addition of probiotics as much as 0.6 ml/L of water, (C) the addition of probiotics as much as 0.8 ml/L of water, (D) the addition of probiotics as much as 1.0 ml/L of water, and (E) the addition of probiotics as much as 1.2 ml/L of water which were maintained for 40 days. The test fish used were 5-6 cm in size and weighed 1-2 grams. The container used was a plastic bucket with a volume of 80 liters with a water volume of 70 liters where the snakehead fish were placed with a stocking density according to the treatment. The amount of feed given was 5% of the fish biomass. The results obtained during the study showed that treatment C with the addition of probiotics as much as 0.8 ml/L of water produced the highest absolute length growth of 2.71±0.05 cm, the highest absolute weight growth of 2.87±0.27 grams, a specific growth rate of 1.69±0.02%, survival of 89±0.03%, the number of erythrocytes 1,356,800±0.02 and the number of leukocytes 120,617±0.07.</p>Rizky Ahmad SudrajatRoffi GrandiosaKiki HaetamiIrfan Zidni
