Kinerja Produksi Elver Ikan Sidat Anguilla bicolor bicolor Berbobot Awal 3 g/ekor dengan Padat Tebar 2 g/L, 3 g/L, dan 4 g/L dalam Sistem Resirkulasi

Abstract

Eels are one of the potential aquaculture commodities but the production technique has not been developed yet. The purpose of this research was to analyze the production performance of eels elver Anguilla bicolor bicolor at different stocking densities: 2 g/L, 3 g/L, and 4 g/L. Initial weight was 3 g/fish. Fish cultured in recirculation system the survival rate and growth performance were observed for 40 days. The experiment was design used Completely Randomize Design (RAL) with 3 replications for each treatment. The data that were obtained consist of survival rate, speed growth rate, weight variance coefficient, and feed conversion ratio. Increasing stocking density enhanced growth performance and decreased the feed conversion. The results showed that the highest growth rate of biomass was produced by the stocking density of 4 g/L of 7.79 g/day compared to those of stocking density of 2 g/L of 3.71 g/day and stocking density 3 g/L of 6.40 g/day.
