Abstract

Feed stability is crucial in aquaculture to minimize nutrient loss and ensure optimal growth of cultured species. This study evaluated the effects of different binders (carboxymethyl cellulose/CMC, wheat gluten, tapioca flour, and Gracilaria sp. flour) at 3% and 5% concentrations, processed via hot and cold mixing methods, on feed stability and survival of mud crab (Scylla spp.). Conducted over 45 days, the research involved feed formulation, stability testing in seawater (30 ppt salinity), and a 30-day feeding trial in a recirculating aquaculture system. Results showed that binder type and processing method significantly influenced feed integrity, with CMC 5% + hot mixing exhibiting the highest stability (96.99% retention after 240 minutes), while tapioca 5% + hot mixing degraded fastest. All formulations met the ≥70% stability threshold after 120 minutes, confirming suitability for aquaculture. The feeding trial revealed 100% survival across all treatments, indicating that binder selection can prioritize physical stability without compromising crab health. Hot processing consistently enhanced binder performance, particularly for polysaccharide-based CMC and Gracilaria sp. flour. These findings suggest CMC 5% (hot) as the optimal binder for durable mud crab feed, whereas tapioca requires careful concentration control. The study provides practical insights for feed development, though further replicated trials under varied farming conditions are recommended to validate commercial applicability. This research contributes to sustainable aquaculture by improving feed efficiency and reducing waste in mud crab production.

Abstract

Sea urchins are a highly nutritious and economically valuable fishery product. In West Nusa Tenggara (NTB), particularly in Lombok, the public is still largely unaware of the benefits and market value of sea urchins in international markets such as Japan and Korea. Sea urchin gonads are consumed by Koreans and Japanese, and their high nutritional content is believed to improve health performance. However, there are obstacles in the sea urchin market development is the lack of proper standard operating procedures in post-harvest handling. Appropriate and standardized post-harvest techniques are not yet widely known or disseminated among sellers and sea urchin business actors. Prima Nusantara Cooperative is one of the cooperatives that supplies fishery products, including sea urchins, to exporting companies. Based on this, the current community service activity was conducted at Prima Nusantara Cooperative in East Lombok, targeting the cooperative staff. The aim is to provide both theoretical socialization and hands-on training to enhance the staff’s knowledge and skills in post-harvest handling of sea urchins. Through this technical guidance, it is expected that the quality of sea urchin products sold to exporters will improve and be more competitive in the Japanese and Korean markets. The method used during the technical training included presentation of materials on proper sea urchin handling procedures, followed by field practice involving sea urchin sampling, hands-on demonstrations, and direct mentoring through each stage of the process. The post-harvest handling stages included harvesting (collection), cleaning, shell breaking, rinsing, weighing, packaging, and storage at low temperatures.

Abstract

Nile tilapia (Oreochromis niloticus) is a widely cultivated freshwater fish due to its adaptability to various environments and ease of breeding. Feed availability is a crucial factor in the success of tilapia cultivation. Quality feed plays a vital role in fish development and using effective feed management strategies can help reduce costs and improve growth outcomes. Previous studies have suggested that coffee grounds can enhance fish immunity and growth due to their antioxidant properties. This research aimed to investigate the impact of adding coffee grounds to commercial feed on the growth and survival of Nile tilapia. The study was conducted over 45 days using a completely randomized design with five treatments and three replications. Treatments included a control group (P1) and feed supplemented with 0.5g (P2), 1g (P3), 3g (P4), and 5g (P5) of coffee grounds per 100g of feed. The results indicated that the addition of coffee grounds significantly affected weight growth, with the highest growth observed in P5. However, no significant differences were found in length growth or specific growth rate (SGR) among treatments. Feed consumption was highest in P2, but feed conversion ratio (FCR) and feed utilization efficiency were most favorable in P5. Water quality parameters remained within optimal ranges throughout the study.

Abstract

Tilapia (Oreochromis niloticus) is one of the freshwater commodities that is most in demand by local and foreign commonities. The increasing price of fish feed has resulted in decreasing income for farmers. One of the feeds that has a high protein content is maggot. One of the procesing technologies to reduce fat content in maggots is by using fermentation technology. Thus, the purpose of this study is to ascertain the impact of fermented maggot flour on the growth of tilapia (Oreochromis niloticus). The experimental design used in this study was a Completely Randomized Design (CRD), with six treatments and three replications, resulting in the production of 18 experimental units: P0 (commercial feed 100), P1 (commercial feed 25% + 75% non-fermented maggot flour), P2 (commercial feed 25% + 75% fermented maggot flour), P3 (commercial feed 75% + 25% non-fermented maggot flour), P4 (commercial feed 75% + fermented maggot flour), and P5 (100% fermented maggot). The addition of maggot flour and maggot fermented flour with different doses, the best treatmens was obtained in P2 (commercial feed 25% + 75% fermented maggot flour). Treatment  P2 could increase the absolute weight growth rate, SGR,EPP, and produced the lowest FCR. However, the addition of maggot flour and maggot fermentation was not significant on absolute lenght growth, feed consumtion level, SR. Thus, the optimal concentration of maggot flour and maggot fermentation in this study was 75% maggot fermentation flour + 25% commercial feed.
