Effect of replacement of fish oil with different plant oils in broodstocks diets on egg and larval antioxidant defense development.

This study was undertaken to investigate the effects of feeding rainbow trout ( broodstocks with different ratio of plant oils to evaluate the changes in antioxidant defense status in the progenies. In the experimental diets, fish oil was replaced with different combination of plant oils including corn oil, olive oil, sunflower oil, and coconut oil, to gain different levels of polyunsaturated fatty acids (PUFA) and highly unsaturated fatty acids (HUFA) in the experimental diets. Fish fed eight weeks with experimental diets before reproduction.
