Effects of feeding two type oxidized oils with and without ethoxyquin were tested for the culture of rainbow trout. One of the oxidized oil was higly peroxidized cod liver oil (P.O.V. 280) and the other was peroxide-decomposed oil prepared by heating the formers'.
Feeding of both oxidized oils without ethoxyquin diets resulted in high rate of death (70%), but in the case with ethoxyquin, it was controlled at the low level (24%).
There observed that the lipid contents in the internal organs of fish fed with oxidized oils containing no ehtoxyquin were higher than that of feeding same oils with ethoxyquin and oxidized lipid appeared in the formers', but not detected in the latters'.
