ABSTRACT

One of the main limiting factors in the reproduction of snakehead fish (Channa striata) 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%.

THE EFFECT OF SHADING ON THE LENGTH OF INCUBATION AND HATCHING SUCCESS OF GREEN TURTLE (Chelonia mydas) EGGS IN PANGUMBAHAN, SUKABUMI, WEST JAVA

2025-05-16T19:06:12+08:00

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.

2025-06-17T20:12:12+08:00

Vannamei shrimp (Litopenaeus vannamei) 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.

2025-04-22T09:24:50+08:00

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.

LOCAL WISDOM AS A STRATEGIC APPROACH FOR SUSTAINABLE FISHERIES RESOURCE MANAGEMENT: A CASE STUDY IN THE RIVERINE WATERS OF BANYUMAS REGENCY, CENTRAL JAVA

2025-04-22T09:26:53+08:00

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.

PROTEIN LEVEL EFFICIENCY OF TILAPIA Oreochromis niloticus FEED WITH SELENOMETHIONINE SUPPLEMENTATION

2025-05-16T19:07:51+08:00

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.

This study aims to obtain the right dosage of multiflora honey in the formation of male sex (masculinization). This study used a Completely Randomized Design (CRD) with 4 treatments and 3 replications. Observation of male sex was carried out after 60 days of maintenance by observing the urogenital organs and 70 days of maintenance with gonad histology using HE staining. The results showed that the highest percentage of males was obtained at a dose of 4 mg/L.

CHARACTERISTICS OF SARDINE FISH OIL EMULSION (Sardinella sp.) FLOUR BY-PRODUCT DURING STORAGE

2025-05-16T19:10:21+08:00

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

CALCULATION OF RESISTANCE AND ENGINE POWER OF PURSE SEINE FISHING BOATS IN TAKALAR REGENCY USING MAXSURF SOFTWARE

2025-05-16T19:09:23+08:00

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.

orthophosphate 0,02-0,089 mg/L. As aquaculture in traditional ponds, air and soil quality
management should be carried out during the preparation and maintenance of milkfish (Chanos
chanos) ponds so that aquaculture management is maintained

VANAME SHRIMP CULTURE AT VARIOUS PRODUCTION SCALES: TECHNICAL AND ECONOMIC REVIEW (LITERATURE STUDY)

2025-05-16T19:10:02+08:00

Vaname shrimp (Litopenaeus vannamei) 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/m² 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/m² 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/m² 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/m²) 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.

Growth (ADG), biomass, survival rate (SR), and feed conversion ratio (FCR). In addition,
measurements of water quality parameters were also carried out in the form of temperature,
pH, Dissolved Oxygen (DO), salinity, ammonia, alkalinity, nitrite, nitrate, and phosphate. The
results of the study showed that the MBW, ADG, Biomass, and SR values of vaname shrimp
cultivated in concrete pond media were higher than those in HDPE ponds. The results also
showed that the FCR value in concrete ponds (1.4) was lower than the FCR in HDPE ponds
(1.5). This means that the FCR of concrete ponds is better than the FCR of HDPE ponds. Water
quality parameters showed different results between HDPE ponds and concrete ponds. In
HDPE ponds, the water quality parameters that were in the optimal range were pH, DO, and
phosphate, while in concrete ponds they were temperature, DO, and phosphate.

EFFECTIVENESS OF LUT-BASED PREBIOTICS IN ARTIFICIAL FEED ON THE GROWTH RATE OF MILKFISH

2025-06-17T20:12:41+08:00

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.

2025-06-17T20:13:08+08:00

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.

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).

EFFECT OF SOAKING IN KASGOT (MAGGOT WASTE) FERTILIZER ON THE GROWTH AND CARAGENAN CONTENT OF SEAWEEDS Kappaphycus alvarezii

2025-03-14T19:15:46+08:00

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.
