Effects of dietary taurine supplementation on growth performance and feed utilization of striped catfish (Pangasianodon hypophthalmus)

Abstract

The study evaluated the effect of dietary taurine supplementation on growth and feed utilization of striped catfish (Pangasianodon hypophthalmus) cultured at salinity (9‰). The experiment was completely randomized with 5 diet treatments with similar protein contents (35%) with different taurine addition levels: 0%, 0.05%, 0.1%, 0.15%, 0.2%. All treatments were assigned in a RAS system of 15 tanks (250 L), and each treatment was triplicated. Experimental fish with initial weight of 17.6 g/fish were stocked 30 fish/tank. The experiment lasted for 56 days. The results showed that striped catfish cultured in brackish water 9‰ required dietary taurine supplementation of 0.05%. At this level, the fish revealed the best growth and feed utilisation.
