dc.description.abstractEffects of different levels of dietary canola oil on growth, feed utilization, and body composition of rainbow trout (Oncorhynchus mykiss) were investigated. Five experimental diets with equal protein (47%) and lipid (17%) contents were formulated to replace 0% (control), 25%, 50%, 75%, and 100% of the fish oil with canola oil. The diets were fed to fish (119 +/- 0.17 g) twice daily to satiation for 70 days. At the end of the experiment, wet weight gain, specific growth rate, relative growth rate, feed intake, feed conversion ratio, protein efficiency ratio, and protein intake were unaffected by the diet treatment (p>0.05). However, apparent net protein retention significantly differed (p<0.05) between the 50% group (33.64 +/- 1.74%) and the control (41.57 +/- 0.46%). The moisture content in the body composition of the fish dropped and the protein and lipid contents rose in all groups from the initial amounts. Our findings suggest that canola oil could be a suitable dietary lipid source for rainbow trout under our test conditions.
