Addition of Lemuru Fish Oil to Protein Retention and Feed Utilization Efficiency of silver barb Rasbora argyrotaenia

Abstract

Abstract Silver barb Rasbora argyrotaenia is one of the local freshwater fish in indonesia that has advantage of being a source of protein and also resistant to disease. This study aims to determine the effect of adding lemuru fish oil to feeds on protein retention and the feed utilization efficiency of silver barb. This study used an experimental method with a complete randomized design consisting of five treatments and four replications. The treatment given is commercial food which is added with lemuru fish oil with different concentrations. In this study it can be seen that the treatments tested were: P0 (0%), P1 (2%), P2 (4%), P3 (6%), P4 (8%). The parameters observed in this study were protein retention and feed utilization efficiency of silver barb. Data analysis using Variant Analysis (ANOVA) and continued with Duncan’s Multiple Distance Test. The results showed that the addition of lemuru fish oil in feed had a significant effect (P<0,05) on protein retention and feed utilization efficiency of silver barb. The highest protein retention in treatment P2 (4%) of 16.95% and the highest efficiency of feed utilization was also found in the treatment of P2 (4%) of 57.93%.
