In this study, effects of substituting different levels of canola meal for fish meal on growth, feed conversion ratio (FCR), somatic indices and body compositions of the angel fish fries were determined. Isocaloric (3500 kcal/kg digestible energy) and isonitrogenic (44% crude protein) six experimental diets were formulated to meet the nutrient requirements of angel fish. Canola meal was substituted as rates of 0%, 8%, 16%, 24%, 32% and 40% dietary crude proteins of fish meal (45.52%) in control diet. Four hundred fifty angel fish were distributed to six experimental groups with three replicates. The experimental results showed that the best weight gain and specific grow rate were found for control and 8% canola meal diets. These criterions were reduced (P<0.05) after 8% canola meal replacement levels. FCR were significantly (P<0.05) deteriorated after 16% canola meal replacement levels. Survival rate ranged between 89.33 and 94.67%, and differences were not significant (P>0.05). With no significant differences, hepatosomatic indices (HSI) and viscerosomatic indices (VSI) values varied from 1 61 +/- 0.13 to 2.03 +/- 0.18 and 7.88 +/- 0.50 to 8.46 +/- 0.36, respectively. Increasing replacement rates of canola meal were tended to decrease crude protein and crude fat contents of fish (P>0.05). As a conclusion, it was suggested that the canola meal can replace up to 16% of dietary fish meal protein without adverse effects in angel fish fry diets.
