Kinerja Produksi Elver Ikan Sidat Anguilla marmorata dengan Padat Tebar 2 g/L, 3 g/L, 4 g/L pada Bobot Awal 7 g/ekor dalam Sistem Resirkulasi.

Abstract

Eels has been known as one of aquaculture commodities with high commercial value. Both local and international demand of eel was relatively high. High market demand of eel could be anticipated wih high elver production which can be applied by increasing the number of eel’s stocking density. The purpose of this research was to analyze the effects of different stocking densities of 2 g/L, 3 g/L, 4 g/L with initial weight of 7 g/eel to the production of elver Anguilla marmorata reared in recirculating system during 40 days. Eels used in this research were at elver stage weighed 7±0.98 g/ eel and length 15±1 cm/ eel. The survival rate for all stocking density in this research was 100%. There are no significant differences found in growth rate, specific growth rate, and weight variance coefficient of all treatments with rate of 0.03-0.06 g/day, 0.38-0.70%, and 14.45-25.29% respectively. The results showed the best stocking density was 4 g/L which showed biomass growth rate and feed conversion ratio were 3.89 g/day and 1.16 respectively
