Abstract

Cangkring Village has various fishery resources, including ponds, fishponds, and access to waters that support fish farming. The Lecturer Returning Home Program aims to disseminate innovations in systems and appropriate technologies for integrated grouper fish farming through survey and training activities. This study used a survey method combined with a descriptive approach. Sampling was carried out using purposive sampling to collect data from fish farmers in Cangkring Village. The survey research was conducted to identify and analyze the potential for grouper (Epinephelus sp.) nursery and rearing based on natural resources in Cangkring Village, Indramayu. Field observations, questionnaires, and interviews were used to collect data. The recommended stocking density is around 32 fish/m3 for grouper fish rearing in KJT measuring 3×6×1 m for an initial weight of 100‒200 g, and 1,500‒2,000 fish/m3 for grouper seeds in KJT measuring 1.5×1.0×0.5 m to 2.5×1.25×0.8 m. Trash fish have great potential for the development of grouper fish breeding in tanks and ponds as well as rearing in floating net cages/floating net cages (KJT) in the estuary waters of the Cimanuk River, Cangkring Village. In addition, the coastal waters and estuaries of Cangkring Village are rich in rebon shrimp, with an abundance of around 900‒1800 fish/L. The larger the fish seeds, the lower the stocking density. This community empowerment activity is an alternative for the community to improve education and skills in fish farming which can later increase income through an integrated system of grouper nursery and rearing based on natural resources.

Abstract

The increase in Nile tilapia (Oreochromis niloticus) production reflects a rise in fish consumption among the community. The provision of sufficient fry for ongrowing must accompany such a production boost. One way to achieve this is through intensification by increasing the stocking density of tilapia larvae during the nursery phase. This study aimed to analyze production performance and the economics of tilapia larva nursery in a recirculation system under different stocking densities. The experiment was carried out over 42 days using a completely randomized design with stocking density treatments of 5, 10, and 15 larvae per liter, each with five replicates. Differences in stocking density had a significant effect on absolute length growth rate (AGRL), specific length growth rate (SGRL), feed conversion ratio (FCR), and productivity. The 15 fish/L treatment yielded higher LPMP, SGR, and productivity than the other treatments, while showing the lowest FCR. It was concluded that the best production performance and economic return in a recirculating tilapia larva nursery system were achieved at 15 fish/L, delivering an annual productivity of 106,112 fish/m³, a revenue-to-cost ratio of 1.54, and a payback period of 0.65 years. Keywords: business analysis, fish tilapia, nursery, recirculation system, stocking density   Abstrak Peningkatan produksi ikan nila (Oreochromis niloticus) merupakan gambaran peningkatan konsumsi ikan di masyarakat. Peningkatan produksi perlu diikuti dengan penyediaan benih yang mencukupi untuk pembesaran. Upaya yang dapat dilakukan adalah dengan intensifikasi melalui peningkatan padat tebar larva nila pada tahap pendederan. Tujuan penelitian ini adalah menganalisis kinerja produksi dan usaha pendederan larva ikan nila pada sistem resirkulasi dengan padat tebar berbeda. Penelitian dilakukan selama 42 hari menggunakan rancangan acak lengkap dengan perlakuan padat tebar larva ikan nila, yaitu 5, 10, dan 15 ekor/L dengan lima ulangan. Perlakuan perbedaan padat tebar berpengaruh nyata terhadap laju pertumbuhan mutlak panjang (LPMP), laju pertumbuhan spesifik panjang (LPSP), rasio konversi pakan (RKP), dan produktivitas. Perlakuan padat tebar 15 ekor/L menghasilkan LPMP, LPSP, dan produktivitas yang lebih tinggi daripada perlakuan lain, sedangkan nilai RKP menunjukkan nilai terendah. Penelitian menghasilkan kesimpulan bahwa kinerja produksi dan usaha terbaik pada pendederan ikan nila bersistem resirkulasi dihasilkan pada padat tebar 15 ekor/L dengan memberikan produktivitas sebesar 106.112 ekor/m3 per tahun, revenue/cost ratio senilai 1.54, dan payback period yaitu 0.65 tahun.

Abstract

Eel aquaculture remains dependent on wild-caught glass eels, whose supply fluctuates seasonally and peaks during the rainy season. Improving nursery efficiency through optimized stocking density is therefore essential. This study evaluated the effects of three stocking densities (1, 2, and 3 g L-¹) on the production performance and financial feasibility of glass eel (Anguilla spp.) nursery operations in recirculating aquaculture systems (RAS). Stocking density significantly affected survival, biomass yield, and profitability (p < 0.05). The highest density (3 g L-¹) resulted in the lowest survival rate (35.69 ± 3.70%), which was significantly lower than both 1 g L-1 and 2 g L-¹, yet produced the greatest biomass (11.42 ± 0.57 g L-¹). Financial analysis showed that all treatments were viable, with 3 g L-¹ yielding the highest profit (IDR 378,035,622 ± 45,089,672). Despite reduced survival, profitability remained relatively stable across treatments, indicating that biomass gain compensated for mortality-related losses. These findings demonstrate that a stocking density of 3 g L-1 provides the most advantageous balance between production output and economic return for glass eel nursery operations in RAS.
