PENGGUNAAN TEPUNG IKAN RINUAK FERMENTASI UNTUK PAKAN ALTERNATIF LARVA LELE DUMBO (Clarias gariepinus BURCHELL)

Abstract

This study aims to determine the effect of fermentation rinuak fish as an alternative feed for larval survival and growth of African catfish . African catfish larvae aged 4 days maintained for 21 days . with stocking density 20 fish / liter and 5 larvae fed with 3 replications treatment , ie treatment A , silk worms ( 100 % ) , Treatment B , silk worms ( 75 % ) + rinuak fermented fish meal ( 25 % ) , treatment C , silk worms ( 50 % ) + rinuak fermented fish meal ( 50 % ) of Treatment D , silk worms ( 25 % ) + rinuak fermented fish meal ( 75 % ) of Treatment E , rinuak fermented fish meal ( 100 % ) . Every day observed on mortality and measured every 7 days long growth . Based on the analysis of variance on the survival of larvae showed that the value of the hit F < F tab , which means survival between treatments provide results that are not significantly different ( non significant ) . Results of analysis of variance showed that the value of the hit F > F tab , as the results of Pricing Duncan Test ( DMRT ) that the absolute length growth between treatment A - B , Treatment A - C and treatment A - D , did not show significant differences . However, treatment A - E provide significantly different results
