Growth and survival rate of silver barb, Rasbora argyrotaenia under different concentrations of sardinelle fish oil addition in fish feed

Abstract Sardinelle fish oil is one of the compositions of the fat source which contains Omega-3 potentially to improve growth performance. The addition of sardinelle fish oil in fish feed is, therefore, important to do to could boost the growth of the fish. This study aims to determine the effect of adding sardinelle fish oil towards the growth performance and survival rate of silver barb and also determines the optimum concentration of sardinelle fish oil in feed formulation that results in the highest growth and survival rate of the silver barb. This research applied a completely randomized design for experimental method, which consisted of five treatments each treatment has four replications in 42 days. The results showed that adding sardinelle fish oil with different concentrations significantly has affected specific growth rate (SGR), feed intake (FI) and feed conversion ratio (FCR), but did not significantly affect survival rate (SR) and average daily length gain (ADGL) of silver barb. Addition of sardinelle fish oil by 4% resulted in SR (100%), SGR (2.17%/day), ADGL (0.85%/day), highest FI (63.81g/50 fish) and lowest FCR (1.73).
