Red sea bream, Chrysophrys major, were kept for 17 weeks on diets containing 9% of one of fresh (O1, POV 5) or oxidized pollack residual oils (O2, POV 550 and O3, POV 1, 550) with or without vitamin B2 and/or E. Fat content of the muscle decreased and moisture increased by the administration of oxidized oil. The administration of O2 oil decreased fat in the hepatopancreas markedly, whereas that of O3 oil kept it on almost the same level as in fish fed the fresh oil. Triglyceride and total cholesterol levels in the plasma decreased in fish fed the oxidized oils, which was enhanced in groups receiving O3 oil or a diet devoid of both vitamin B2 and E. Plasma protein concentrations decreased in the groups fed the oxidized oils and vitamin deficient diets, but A/G ratios and plasma glucose levels were not affected by the oxidized oils. The activity of plasma glutamic-oxalacetic transaminase increased in groups fed the oxidized oils.
