Abstract

The intertidal zone is an area that has a narrow area because it borders land and is influenced by tides. The types of biota in tidal areas have high diversity. There are many types of biota such as fish, bivalves, coral reefs, gastroda and there are also types of plants such as macroalgae, seagrass and mangroves. One of the biota found in tidal areas is Gastropods from the phylum mollusca which has quite abundant species diversity. With location conditions such as sandy, muddy and rocky substrates. Moudong waters are waters that have rocky and muddy topography, so they are a place/habitat for gastropod species. The aim of this research was to see the level of diversity of gastropod types and nutritional content. The method used is the observation and line transect method, with 9 stations and 9 plots on each transect. Based on the results of research on the types of gastropods in Moudong waters, there are 5 types of gastropods, namely Oliva fordi, Telescopium Telescopium, Steromphala umbilicalis, Canarium labiatum, Familia muricidae. The level of diversity of gastropod species is low with an H' index < 2.0, because there is only 1 type at each sampling station. For nutritional content (proximate analysis results), it was found that the nutritional content of the gastropod species obtained in Moudolung waters was quite high, one of which was that the protein content of each type was quite high.

Abstract

Hatchery activities have several stages, starting with broodstock management, preparation of larval containers, broodstock selection, brood spawning, egg handling, larval rearing, feeding management, water quality management and harvesting. The aim is to find out knowledge about white snapper (Lates calcarifer) hatchery techniques at the Brackish Water Aquaculture Center (BPBAP) Situbondo, East Java. The research method used is the descriptive method. The research results showed that the number of broodstock used in the natural spawning process was 84 with a ratio of 1:2, carried out twice during the dark and bright months at night. The harvested eggs were spread in rectangular concrete tanks for 17-18 hours and the HR (Hatching Rate) was calculated with a yield of 96%. Feeding D2-D30 larvae is given 2 times a day with types of feed in the form of natural and artificial feed, D23-D35 larvae feed is given once every 2 hours in the form of artificial feed. The results of measuring water quality parameters were a pH value of 7.75, a salinity value of 30 ppt, a temperature value of 31oC, a dissolved oxygen value of 6.12 mg/L and an ammonia value of 0.085 mg/L. Water management is carried out by siphoning and changing the water according to the age of the larvae. Harvesting of larvae is carried out after grading size and defects and then calculating the SR (Survival Rate) value which is found to be 30%.

Abstract

Folding bubu fishing gear is one of the fishing gear operated to catch mangrove crabs in Pangkal Babu Village, catching mangrove crabs (Scylla serrata) using folding bubu fishing gear requires bait in an effort to increase catches effectively. This study aims to determine the difference in mangrove crab catches using stingray and tobul fish bait using folding bubu. This research was conducted in Pangkal Babu Village, Tanjung Jabung Barat on March 7 - April 7, 2024. The method used was experimental fishing. Data collected include the number, weight and width of mangrove crab catches, the number, weight, and width of the carapace of the catches are tabulated in the form of tables and graphs. The results showed that the number of mangrove crab catches was 27 with an average total weight of 407.8 g and an average carapace width of 198.4 mm. While the catch of mangrove crabs with tobacco fish treatment got 34 fish with an average weight of 602.4 g, and an average width of 267.6 mm. The results of the T test analysis showed that the bait type treatment had no significant effect (P> 0.05) on the number of mangrove crab catches, but had a significant effect (P < 0.05) on the weight and width of the mangrove crab carapace, From this study, it can be concluded that the use of tobacco fish bait in folding bubu fishing gear in Pangkal Babu Village resulted in higher carapace weight and width compared to the use of stingray bait.

Abstract

This study aims to evaluate the financial performance of the koi fish farming industry (Cyprinus rubrofuscus) in Indonesia through a selective breeding program. Data collected between 2021 and 2024, covering business development, operational costs, investment costs, and capital estimates, was obtained from 24 koi fish farming businesses in the Java region. Businesses using genetic screening aim to reduce financial disparities, which is different from traditional aquaculture methods. The analysis's results indicate that the implementation of the selective breeding program in a scientific manner yielded a higher profit margin of 34.2% than the traditional method, which only reached 18.7%. Although the initial investment is more substantial (about Rp28,5 million per hectare), the time frame required to pay for the investment is more efficient, i.e., between 18 and 24 months. The price of koi fish is higher than the market price, possibly reaching 2.8% of the price of koi fish, with the selling price per tail ranging from Rp450,000 to Rp1,200,000. In addition, there was a 15% increase in feed efficiency and a 3% decrease in mortality, which means a 7.8% reduction. Thus, this selective breeding program can improve koi farming production and sales performance by applying genetic technology, which can help overcome the financial crisis in the aquaculture sector in developing countries.

Abstract

The nilem fish (Osteochilus vittatus) has high economic value, but its growth rate is relatively slow. One potential solution to accelerate its cultivation period is the use of recombinant growth hormone (rGH). This study aimed to evaluate the effect of oral administration of rGH derived from Epinephelus lanceolatus (rElGH) on the growth rate of nilem fish juveniles at different stocking densities. A completely randomized design with three replications was used in this study. Juvenile fish with an average length of 4.43±0.03 cm and weight of 0.96±0.03 g were reared in aquaria measuring 100 × 50 × 50 cm with a water height of 20 cm for 30 days. The fish were fed commercial feed containing 31–33% protein, with rElGH-supplemented feed given to satiation twice daily (at 08:00 and 16:00) during the first seven days, followed by regular feed without rElGH. The best production performance was obtained in the R30 treatment group (30 fish per 100 L with rElGH), with an absolute weight gain (AWG) of 3.4 g, a survival rate of 98.89%, and a specific growth rate (SGR) of 4.8% per day, indicating that nilem fish given rElGH grew faster.

Abstract

Feed is a very important factor because it takes up 60-70% of the total operational costs, so that feed provided according to needs will stimulate optimal growth and development of shrimp production. The use of auto feeder machines can help in providing shrimp feed more effectively and maintaining water quality to remain stable and suitable for vannamei shrimp cultivation. The purpose of this study was to determine the efficiency of feeding in vannamei shrimp ( Litopenaeus vannamei ) cultivation . The method used in this study is the method descriptive, the data analyzed in this study is shrimp growth data obtained from sampling results and water quality data both in the field and laboratory. The results of this study are that the daily growth (ADG) of vannamei shrimp is in the range of 0.22-0.38 grams, this data is already optimal and for the average weight (MBW) obtained 4.56 grams then increased over time to reach DOC 108 with a weight of 24.97 grams. Based on the results of the average weight growth obtained, it is known that the growth is optimal and it is known that the water quality value is still in optimal condition in vannamei shrimp cultivation, both physical and chemical parameters. From this study it is known that feeding using an auto feeder has a good effect on the growth of ADG and MBW shrimp and also the feed given using an auto feeder can minimize feed falling to the bottom so that water quality is maintained and remains in optimal condition for vannamei shrimp cultivation.

Abstract

Mangrove crab (Scylla spp.) aquaculture has high economic potential, but its implementation in coastal areas such as Central Tapanuli Regency still faces challenges, including limited land, water quality fluctuations, and maintenance efficiency. This study aims to develop and test the effectiveness of the Crab Flow System (CFS), a modular crab culture system based on controlled water flow designed to improve crab growth and survival performance. The research was conducted from January to March 2025 at the Laboratory of the Matauli College of Fisheries and Marine Sciences, North Sumatra, using an experimental method with two treatments: (1) conventional culture and (2) culture using CFS, each with three replicates. Parameters observed included daily growth rate (SGR), survival, and water quality (temperature, pH, DO, ammonia). Results showed that the use of CFS resulted in 18.4% higher average daily growth and 92% survival rate, compared to the conventional system. Water quality in the CFS system was also more stable and within the optimal range for crab growth. In conclusion, the CFS system proved to be effective in increasing the efficiency and productivity of crab culture, and has the potential to be an innovative solution for the development of sustainable aquaculture in coastal areas.

Abstract

The waters of the Makassar Strait in the Donggala Regency of Central Sulawesi, which is directly opposite the Capital City of the Archipelago (IKN), have the potential for Duwo fish resources as animal food. Duwo fish is included in the Gobiidae family, a type of fish with the highest diversity. In Sulawesi, Awaous melanocephalus is a native species in several areas, in Gorontalo it is known as Nike, in Mamuju, West Sulawesi it is known as Penja fish, and in Central Sulawesi it is known as Duwo fish. Duwo fish can be consumed raw and is generally consumed after being processed and dried. This study aims to analyze the added value of Duwo fish ( Awaous melanocephalus ) in Donggala Regency, Central Sulawesi. Data collection was obtained from Duwo fish processing business actors in Donggala Regency using a purposive sampling research method. Data analysis used the Hayami method of added value analysis. The results of the study showed that the processing of dried duwo fish produced an added value of Rp. 2,500/kg. The ratio of added value obtained with an output of 33.33%, this shows that for every Rp. 100, the added value of dried dowu fish is 33.33 . The processing business of dried duwo fish is one of the forms of business that is pursued by the coastal community of Donggala Regency, Central Sulawesi because it can provide a promising source of income.
