The present study was conducted to evaluate the effect of different dietary protein levels on digestive enzyme activities, nutrient assimilation as well as growth performance in striped catfish (Pangasianodon hypophthalmus). Fish were fed with four semi-purified formulated diets with increasing levels of protein: 30% (CP30), 35% (CP35), 40% (CP40) and 45% (CP45) for 12 weeks. At the end of the feed trial, the highest weight gain (29.88 g fish-1), specific growth rate (3.58%) and lower feed conversion ratio (1.91) were observed in fish that were fed with a 40% protein diet while CP30 treatment group had the poorest growth performance indicators (P |
