Global development in the manufacture of aquatic food make the researchers to find out some suitable substitution for fish and soybean meal to reduce the price especially in omnivorous and herbivorous fish like tilapia. Canola as an oil seed plant protein source can be a good candidate. To examine this, five iso-caloric experimental diets (gross energy, 4.61 Kcal/g) were formulated to contain graded levels of 0 (control), 25%, 50%, 75% and 100% canola meal replaced with soybean and fish meal. The results showed that there was a significant negative effect on growth performances by canola enhancement for feed and protein intake reduction because of bitter taste of some anti-nutrients. But, the indices of feed and protein performances such as FCR, PER, PCE did not exhibit any significant difference until 50% replacement. So, it could be predicted that if the problem of palatability discard, canola replacement can be happen until 50% for growing Nile tilapia.
