A 180-day feeding trial was conducted with Pangasianodon hypophthalmus fingerling (initial weight of 12.40 ± 0.04 g) to examine the effects of partial substitution of canola meal in prepared diets on growth, feed conversion ratio (FCR), somatic indices, and survival rate. Four isonitrogenous (30% crude protein and 5.5% crude lipid) diets were formulated to contain 10%, 20% and 30% canola meal against no canola meal (control group). A total of 1,280 tra catfish were distributed into 4 experimental groups with 4 replicates. At the end of the experiment, there were no significant differences on growth, feed conversion ratio (FCR), somatic indices, and survival rate (P > 0.05). This study showed that canola meal could replace standard diets by up to 30% in Pangasius catfish without adversely affecting performance.
