Abstract

Sea grape (Caulerpa lentillifera) is a strategic green macroalgae with significant potential in aquaculture and functional food industries. However, its cultivation remains constrained by limited production techniques. This study investigated the influence of nitrogen concentration on C. lentillifera growth in a laboratory-scale cultivation system. A completely randomized experimental design was implemented with four treatments: a control group (0 ppm) and nitrogen supplementation levels of 5, 10, and 15 ppm, each replicated thrice over 21 days. Results demonstrated a significant positive correlation between nitrogen concentration and growth parameters. The 15 ppm nitrogen treatment exhibited the highest absolute growth (3.37 g), relative growth rate (13.50%), and specific growth rate (1.82% per day). Interestingly, no statistically significant difference was observed between 10 and 15 ppm treatments, suggesting a potential nitrogen uptake saturation point. Water quality parameters remained stable throughout the experiment, with temperature ranging from 28-30°C, salinity at 33-34 ppt, dissolved oxygen between 5.9-6.7 ppm, and pH maintained at 7.5-7.8. The study provides crucial insights into nitrogen's role in C. lentillifera cultivation, offering a scientific foundation for developing more efficient and sustainable macroalgae production strategies in aquaculture and functional food industries.

Abstract

Freshwater prawn (Macrobrachium rosenbergii) is a freshwater species which intensively cultivated. Calcium (Ca) and magnesium (Mg) are crucial factors supporting the biological and physiological activities of freshwater prawns. The presence of calcium and magnesium minerals in the environment is utilized by the prawns, especially after the molting process. Calcium and magnesium play roles in osmoregulation and the formation of the prawn's carapace. This study aims to determine the optimal ratio of calcium and magnesium minerals to support molting frequency, specific growth rate, survival rate, and feed efficiency.The experimental design used in this research is a completely randomized design (CRD) with five treatments and three replicates. The treatment given consisted of increasing Ca-Mg in the media: A: 30 mg l-1 Ca + 0 mg l-1 Mg (1:0); B: 30 mg l-1 Ca + 15 mg l-1 Mg (1:0.5); C: 30 mg l-1 Ca + 30 mg l-1 Mg (1:1); D: 30 mg l-1 Ca + 45 mg l-1 Mg (1:1.5) and E: 30 mg l-1 Ca + 60 mg l-1 Mg (1:2). Based on the result, treatment C: 30 mg l-1 Ca + 30 mg l-1 Mg (1:1) was found to improve molting frequency, growth rate, feed efficiency and survival rate.

Abstract

The catch of fishermen around Ampenan waters is dominated by Mackerel scad and rucah. Fish caught by fishermen around Ampenan waters are usually landed at the Ampenan fish market to be traded. Mackerel scad (Decapterus sp.) is a pelagic fish that lives in groups and is spread out. Mackerel scad (Decapterus sp.) In addition to having a cheap price, Mackerel scad (Decapterus sp.) also has good nutritional value so that Mackerel scad is included in important economic products. The biological aspect in the form of the relationship between length and weight in Ampenan waters is important to study in efforts to manage fisheries in West Nusa Tenggara, especially Ampenan. Efforts to manage fisheries through fisheries biology information related to the relationship between length and weight aim to determine the variation in weight and length of Mackerel scad (Decapterus sp.) individually or in groups as an indicator of the productivity, health and growth conditions of Mackerel scad obtained in these waters. The study was conducted in March 2024 using survey methods and regression analysis. The number of samples used in this study was 50 Mackerel scad (Decapterus sp.) which were taken randomly at the Ampenan fish market. The results of linear regression and graphs of the relationship between the length and weight of Mackerel scad samples (Decapterus sp.) in this study produced a regression equation Y = 0.04855x 2.2973 with a coefficient of determination (r2) of 62% and a b value of 2.29, meaning b <3 which means negative allometric which means that length growth is faster than weight growth.

Abstract

This study investigates microplastic contamination in whiteleg shrimp (Litopenaeus vannamei) cultivation systems, focusing on water, feed, and shrimp health. Microplastics, which pose significant threats to aquaculture, are often ingested by shrimp, potentially causing physiological damage and reducing product quality. The research was conducted from June to September 2024 at PT—X in North Lombok Regency. Samples of water, shrimp organs (intestines, stomach, and gills), and feed (pellets and crumbles) were analyzed for microplastic contamination. Results revealed a high presence of microplastic fragments in both shrimp and feed, with a significant reduction in microplastic particles after water filtration treatment. Specifically, the water reservoir contained 71 microplastic particles before treatment, with fragments being the most prevalent, and decreased to 8 particles post-treatment. The pelleted feed showed 102 microplastic particles, with fragments comprising 90 of them. Similarly, crumble feed contained 49 microplastic particles, predominantly fragments. The findings emphasize the significant role of microplastic pollution from the surrounding environment and the feed production process in shrimp farming. This study provides essential insights into the sources and impact of microplastics on shrimp health and the quality of aquaculture products, advocating for improved management practices and environmental awareness to mitigate contamination risks.

Abstract

One material that can be used to improve feed quality is octopus ink. Octopus ink can serve as an alternative nutrient source to optimize catfish growth. Ink produced by cephalopods such as squid, octopus, and cuttlefish contains various components, including fat, protein, ash, and carbohydrates. The aim of this research is to determine the effect of administering octopus ink extract (Octopus sp.) on the growth of catfish (Clarias sp.) infected with Aeromonas hydrophila bacteria. The method used in this research was experimental, involving five treatments with three replications: treatment 1 (Control/P1), treatment 2/P2 (40 ml/kg), treatment 3/P3 (80 ml/kg), treatment 4/P4 (120 ml/kg), and treatment 5/P5 (160 ml/kg). The research steps included octopus ink extraction, a Lethal Concentration 50 (LC50) test, preparation of tools and materials, supplementation of octopus ink extract in feed, application of test treatments, challenge tests with Aeromonas hydrophila, and maintenance. The results of this research showed that treatment 5 (160 ml/kg) yielded the best outcomes in growth parameters, including an absolute weight of 1.26 grams, a specific growth rate of 0.57%/day, a feed convertion ratio (FCR) of 1.66, and a survival rate of 90%.

Abstract

Mendahara Ilir is an area located on the coast with the majority of the community working as fishermen. Fishermen in this area catch fish using Gillnet fishing gear. Overfishing is a form of excessive fishing, the fish population is decreasing over time so that it can cause extinction and will cause degradation of fish resources leading to the extinction of the Senangin species. The purpose of this study was to determine the morphometric and meristic measurements of Senangin (Eleutheronema tetradactylum) in the waters of Mendahara Ilir which can be used as a consideration in making fisheries resource management policies. The method used in this study was the survey method. Data collection was carried out on 30 Senangin samples. Morphometric measurements used 11 characters and meristic calculations used 7 characters. The results of this study showed that the longest Senangin was 65.8 cm and the shortest was 19.0 cm. The average length of the Senangin obtained was 34.7 cm. The determination coefficient R2 of senangin from morphometric characters to total length (TL) ranges from 0.94 to 0.99 where the value shows a very close relationship. The correlation results are influenced by food availability. Meristics of senangin are D.II; D17-19, A.II: A15-70, P.II: 10-76, C.II: 31-182, scales on the tail stem with a total of 136 and a minimum number of 40, lateral line scales with a total of 170 and a minimum number of 62. The conclusion is that Senangin in the Mendahara Ilir waters are still well maintained habitat in Mendahara Ilir.

Abstract

The characteristics of mangrove ecosystems as public goods have great potential for degradation if they continue to experience pressure and the absence of sustainable management. The impact will be reduced economic value and require considerable rehabilitation costs to overcome other negative impacts that may occur in the community. This study was conducted to estimate the total economic value of mangrove ecosystems in Amahai Village, Central Maluku District. Respondents are 30 local communities selected by purposive sampling and 1 owner of the mangrove tourism by total sampling. Data analysed using quantitative methods. The results showed that the utilisation of mangrove resources by local communities consisted of fish, shrimp, crab, eco-tourism, research and education. The total economic value (TEV) with an area of 43.9 ha is IDR 5,899,162,139/year or IDR 134,377,270/ha/year, which consists of direct use value IDR 189,839,601/year, indirect use value IDR 5,619,753,331/year, option value IDR 21,025,247/year, existence value IDR 49,560,000/year, and bequest value IDR 18,983,960/year. This economic value indicates that the mangrove ecosystem plays an important and strategic role in the lives of local communities. Therefore, this value can be a source of information for the government as a policy holder in managing mangrove ecosystems in Amahai Village.

Abstract

Most of the Central Tapanuli Regency area is on the coast, which is part of the Indian Ocean waters and has great potential in the fishing industry, especially marine fisheries. One of the fishing gears widely used by fishermen in Central Tapanuli is the gill net. Although the amount of marine fisheries resources in Central Tapanuli is quite abundant, the catch of gillnet fishermen often fluctuates, so fishing aids are needed to increase catches, one of the efforts made is using LACUBA. This research was conducted from February to April 2024 in Sibolga Bay, Central Tapanuli. This study used a completely randomised design (CRD), with the first 30 metres of gill net treatment with LACUBA and the remaining 30 metres without LACUBA treatment with a total net length of 60 metres. The results showed that the catch of gill nets using LACUBA influenced the catch, the total catch was 16,845 grams, without LACUBA 8,290 grams for 14 times. Gill nets with LACUBA can increase catches compared to without LACUBA, due to the addition of attractants to the net, so that fish including positive phototaxis will be caught in the net, besides that fish that are looking for prey are also caught because they want to prey on their food in the gill net area.

Abstract

Efforts to combat disease in farmed fish are typically done using antibiotics. However, long-term use of antibiotics can lead to disease resistance and environmental pollution. One herbal extract with potential as an immunostimulant is the soursop plant (Annona muricata L.). This study aims to understand the hematology of tilapia (Oreochromis niloticus) that were fed a diet mixed with soursop leaf extract (Annona muricata L.). The study design included four treatments and three repetitions, comprising treatment A (control), treatment B (2.5 g/kg feed), treatment C (5 g/kg feed), and treatment D (7.5 g/kg feed). The results showed that feeding a diet mixed with soursop leaf extract at a concentration of 7.5 g/kg feed (treatment D) could influence the increase in hematocrit levels by 26.11%, hemoglobin levels by 7.11 g/dl, and total leukocytes by 4.41 x 104 cells/mm3, but did not affect the total erythrocytes of tilapia.
