Abstract

In intensive fi sh farming, feed costs can reach up to 70% of the total cost production, so that its effi ciency needs to be improved. The aims of this study were to improve fi sh growth rate and feed effi ciency for rabbit fi sh grow-out through supplementation of crude papain enzyme in the feed. Test fi sh were juvenile of rabbitfi sh, Siganus guttatus, with average initial weight of 40±3.5 g. Fish were stocked in 12 of 1×1×2 m3 fl oating net cages with density of 16 fi sh/cage. As dietary treatments were different dosages of crude papain enzyme namely (A) 0%, (B) 0.0125%, (C) 0.025%, and (D) 0.050%. The rabbitfi sh were fed to satiation in the morning and afternoon for 120 days. The results showed that specifi c growth rate, survival rate of the fi sh, feed effi ciency, protein effi ciency ratio, and the level of feed intake were not signifi cantly different (P>0.05) among treatments. However, there was a tendency that increasing of supplementation level of crude papain enzyme in diets, fi sh growth rate, feed effi ciency, and protein effi ciency ratio also increased.
