RECIRCULATING AQUACULTURE SYSTEM FOR ORNAMENTAL FISH PRODUCTION (LITERATURE REVIEW)

Thu, 19 Dec 2024 00:00:00 +0800

Ornamental fish have their own charm due to the beauty of their shapes and color patterns. Ornamental fish have good sales prospects and have high economic value, so many ornamental fish hobbyists and breeders are involved in them. Cultivating ornamental fish is certainly not free from obstacles, such as ponds or aquariums that have been contaminated with microbes which can cause fish to get sick or even cause death. One way to maintain fish health while increasing ornamental fish production is to monitor water quality. Efforts that can be made to overcome the above problems are to apply a recirculating aquaculture system. This study aims to provide information on the use of an effective aquaculture recirculation system to increase ornamental fish production while reducing ornamental fish mortality rates. The information that will be provided is a study from several journals regarding circuits for recirculation systems and optimizing the use of filter combinations in recirculation systems.

Simon Tubalawony, Ana Yeti Huwae — Thu, 19 Dec 2024 00:00:00 +0800

Upwelling is the rise of water mass in the lower layer to the surface. The rise of water mass is due to wind moving above the waters so that this wind will push the water mass on the surface as a result of which water from below replaces the emptiness above. The variation in SST distribution is relatively lower and the abundance of chlorophyll as an indicator of the occurrence of the upwelling phenomenon and the effect of wind on the upwelling phenomenon. The purpose of this study was to determine the variability of SST and chlorophyll in the waters of South Buru Island to Seram Island and its effect on the upwelling phenomenon. The method used is a quantitative method with the aim of describing the state of SST and Chlorophyll in the Waters of South Buru Island to Seram Island. The results of the study showed that the analysis of the distribution of SST and chlorophyll from June to October was an upwelling phenomenon with SST in June 28.15 ° C and chlorophyll-a 0.44 mg / m³ with an average wind speed of 4.58 m / s which was the beginning of the upwelling phenomenon. For July, the SST distribution was 27.21°C and chlorophyll-a 0.54 mg/m3 with an average wind speed of 5.42 m/s. In August, the SST distribution was 26.95°C and chlorophyll-a 0.58 mg/m³ with an average wind speed of 5.32 m/s. In September, the SST distribution was 27.73°C and chlorophyll-a 0.50 mg/m³ with an average wind speed of 4.09 m/s, while in October, the distribution was 28.97°C and chlorophyll-a 0.29 mg/m³ with an average wind speed of 2.65 m/s.

Achmad Syauqibik, Junianto Junianto — Thu, 19 Dec 2024 00:00:00 +0800

Fishmeal is a processed fish product that has the potential to improve food nutrition. This article aims to review the utilization of fishmeal in improving the nutrition of food products. The method used was a literature study and systematic review by analyzing 26 research articles published between 2014-2024 and 1 ministry report in 2020. Data were analyzed descriptively comparatively, focusing on the preparation of fishmeal, proximate composition of fishmeal, and proximate composition of food products resulting from fishmeal substitution. Results showed that the best method of making fishmeal was steaming and fat extraction, resulting in a brighter and cleaner flour. The proximate composition of fishmeal varies depending on the type of fish. Substitution of fishmeal in food products such as cookies, flakes, pizza bases, and pastries significantly increased the nutrient content, especially protein, calcium, and phosphorus, while decreasing the moisture content. Despite this, the nutritional content of these products still meets quality standards and is safe for consumption. Fishmeal is effective in increasing the nutritional value of food products, making it a promising alternative for food diversification and fortification to address malnutrition in the community.

Thu, 19 Dec 2024 00:00:00 +0800

Batak fish (Neolissochilus thienemanni) is an endemic species that has important ecological, economic, and cultural values for the local people of North Sumatra. However, the population of this fish has experienced a drastic decline due to environmental factors such as water quality, climate change, and pressure from human activities, such as overfishing and water pollution. One of the important aspects in Batak fish cultivation is environmental conditions, especially water height or water depth factors. Water height plays a big role in determining the quality of fish habitats, including water temperature, dissolved oxygen levels. The purpose of this study is to determine the effect of water height variations on the response, behavior and growth of Batak fish in the aquaculture environment. The study was conducted with an experimental design using a Complete Random Design (CRD) consisting of three water height treatments: 15 cm, 20 cm, and 25 cm. Observations were made every 10 days to measure the weight, length of fish, and water quality. The results showed that the water height had a significant influence on the growth of the weight and length of Batak fish. Treatment with a water height of 25 cm indicates optimal growth, while treatment with a water height of 15 cm and 20 cm indicates lower growth. The results of the study obtained where the P3 treatment (25 cm) provided the average value of the growth rate of both weight and absolute length of the highest per treatment. In other words, the average P3 is different from P1 and P2. The water level of different cultivation media affects the total water volume and movement space for Batak fish in the same cultivation container on the aquatic environmental conditions and behavior of Batak fish.

Saleh Bay is a region in West Nusa Tenggara Province known for its significant marine resource potential, on which most coastal communities rely for their livelihoods. One of the most important activities for these communities is seaweed cultivation. Besides supporting the local economy, this activity has also made West Nusa Tenggara one of the largest seaweed producers in Indonesia. However, declining water quality has led to a decrease in seaweed production. This issue has occurred in certain areas of Saleh Bay, such as Labuhan Sangoro. This decline commonly happens during specific seasons (the rainy season) and as a result of ice-ice disease. Monitoring water conditions is essential to provide a reference for seaweed farmers on the water quality in their cultivation areas. This study was conducted in February 2024, coinciding with the rainy season. Water sampling was carried out using purposive sampling at six stations, which were cultivation locations (sampling stations from the previous year). Measurements of seawater chemical and physical parameters were conducted in situ and at the Lombok Marine Aquaculture Center Laboratory. The data obtained from these measurements were then analyzed descriptively using the Pollution Index method based on the Indonesian Minister of Environment’s Decree No. 115 of 2003. The Pollution Index evaluation indicated that in February 2024, the waters of Labuhan Sangoro remained at a moderate pollution level (PI=6.1), with some stations showing parameter values exceeding the quality standards.

Fiqih Muharby, Laura Siahainenia, Yuliana Natan — Wed, 25 Dec 2024 00:00:00 +0800

Hutumuri Country has beaches which can be said to be strategic water areas due to their proximity to residential areas. The potential resource of sea urchins makes people use sea urchins as food animals when the seasons change. There are several types of sea urchins that are used as food by local people. Such as being used as a berth for fishing boats, bameti and other coastal activities which can result in disruption of the presence of aquatic organisms, including sea urchins (Echinoidea). The results of research at the Hutumuri State Beach location show that the level of gonad maturity in the Tripneustes gratilla species during the east season consists of 2 levels of gonads, and is moniated by (TKG III) with a size range of 51 - 60 mm wide in diameter. Meanwhile, during the transition season I, individuals were obtained with (TKG V) in the range of diameter 56 - 72 mm. The Echinometra mathaei species shows a gonad maturity level during the east season of 3 gonad levels, and is dominated by (TKG IV) with a diameter of 26 - 35 mm. Meanwhile, in the transition season I it was monasted by (TKG V) with a size range of 35 - 45 mm wide diameter. In the eastern monsoon, the Diadema antillarum species found that gonad maturity occurred at stages (TKG I & II) with a size range of 95 - 105 mm in width. Meanwhile, during the first season, the Diadema antillarum species could not be found at the research location, which is thought to be due to the influence of the season.

Kristina Haryati — Wed, 25 Dec 2024 00:00:00 +0800

Sardines, or lemurs fish, is a type of pelagic fish commonly found in the waters of the Bali Strait, with high oil content but low quality, although it still contains important elements for health such as omega 3. This research aims to identify the fatty acid profile of sardine fish oil as a source of omega 3 before and after purification. The method used in this research is divided into two parts: purification and testing of fatty acid profiles. The purification process is divided into 3 stages: degumming with citric acid, neutralizing sodium hydroxide (NaOH), and whitening using 5% magnesol XL. Fatty acid profile testing is divided into 3 stages: fatty acid extraction, methyl ester formation, and fatty acid identification. The results showed that the percentage of Saturated Fatty Acids (SFA) in crude oil and pure oil was 30.06% and 22.85%, respectively; for Monounsaturated Fatty Acids (MUFA), it was 11.84% and 8.83%, while multi-chain unsaturated fatty acids (PUFA) were 24.46% and 21.52%. The percentage of omega 3 in crude fish oil and pure oil is 20.89% and 14.87%, respectively; omega 6 is 3.35% and 6.53%; and omega 9 is 6.15% and 5.24%. These findings show that PUFA has a significant percentage after SFA, and the highest PUFA content is omega 3, especially Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA). Thus, this research shows that pure fish oil has the potential to be further developed into products rich in omega 3.

The Gili Sulat and Gili Lawang Marine Recreation Park (TWP) has a significant diversity of reef fish, but fishing activities threaten its stock. This research aims to estimate the stock condition of reef fish using a length-based stock assessment approach and Spawning Potential Ratio (SPR) analysis. Data were collected from two fish landing sites throughout 2023, covering fish species, catch results, and fish length data. A CPUE (Catch Per Unit Effort) analysis was conducted to assess fishing efforts and catches, while SPR was used to evaluate the stock condition of the fish. The research results show that 151 species of reef fish were caught, with three dominant species: Naso thynnoides (35%), Acanthurus mata (33%), and Caesio caerulaurea (32%). The SPR values of these three species were above 30%, indicating relatively healthy stocks (Naso thynnoides 58%, Acanthurus mata 43%, Caesio caerulaurea 34%). However, the exploitation rate of Acanthurus mata indicates that this species is fully exploited (E=0.578), requiring strict management to prevent overfishing. In conclusion, most reef fish stocks are in good condition, but Acanthurus mata requires special attention. Fishing control and regular monitoring are recommended to maintain the sustainability of reef fish stocks in TWP Gili Sulat and Gili Lawang.

Integrated Multi-Trophic Aquaculture (IMTA) has limitations in its application due to the requirement for large cultivation areas. To address this issue, the IMTA system has been modified into the yumina bumina system, utilizing freshwater mussels (Anodonta woodiana) as suspension feeders and water spinach (Ipomoea reptans) as nitrogen absorbers. This study employed a completely randomized design with three treatments: (A) Nile tilapia without freshwater mussels, (B) Nile tilapia with 25 freshwater mussels per 15L, and (C) Nile tilapia with 50 freshwater mussels per 15L, over a 30-day period. The results indicated that the addition of freshwater mussels increased nitrite and nitrate levels in treatments B and C, yet supported specific growth rates of Nile tilapia in terms of length and weight, with the highest values observed in treatment C (1.05%/day) and B (3.75%/day), respectively. The system also achieved a survival rate of Nile tilapia above 80% with acceptable water quality parameters, including neutral pH (7.86–8.16) and high dissolved oxygen levels (17.77–18.02 mg/L). This integration demonstrates significant potential for optimizing Nile tilapia production efficiently while ensuring environmental sustainability.
