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

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.

Abstract

This study aims to evaluate the effect of stocking density variation on the survival rate of Asian Redtail catfish juveniles (Mystus nemurus) in a closed wet transportation system for 12 hours and post-transportation maintenance for 4 days. The method used a completely randomized design with three density treatments: 83, 167, and 250 fish per liter, each replicated three times. The results showed that a stocking density of 167 fish per liter provided the best survival rate, reaching 100% at the end of transportation and 95,45% after post-transportation maintenance. At the highest density of 250 fish per liter, a significant decline in survival to 64,39% was observed, accompanied by decreased water quality, lowered dissolved oxygen levels, increased ammonia concentration, and physiological stress symptoms in the juvenile. The decline in water quality and accumulation of metabolic waste at high densities contributed to increased stress and mortality. Besides the biological aspects, the business analysis indicated that a stocking density of 167 fish per liter was optimal in terms of economic efficiency, generating a net profit of IDR 21.467 and an R/C ratio of 1,09, making this scenario commercially viable. This study offers valuable recommendations for the sustainable management of Asian Redtail catfish juvenile transportation, promoting increased production and profitability in aquaculture.
