The study was conducted preliminarily to examine the effect of dietary pollock liver oil on the growth of rainbow trout and to clarify the effective components in the oil by feeding the two principal fractions, nonsaponifiables and total fatty acids, separated from pollock liver oil. The results showed that pollock liver oil had a superior food value for fish growth and that its fatty acid fraction was the principal element, judging from the growth conditions and analytical data. In addition, a diet containing methyl linolenate in a quantity comparable to the total amount of ω3 fatty acids contained in pollock liver oil produced better growth, but the growth enhancing effect of the methyl linolenate was far less than that of the original pollock liver oil. It was thus postulated that ω3 highly unsaturated fatty acids in pollock liver oil may have a higher efficiency than that of linolenic acid in a manner similar to the relationship existing between linoleic and arachidonic acids in mammals.
