The relation between lipochrome pigments and vitamin A in the nutrition of young fish

Abstract
The ova of brown and rainbow trout contain a pigment similar to, but not identical with, carotene, probably a hydrocarbon. During development the amt. of this pigment decreases, with corresponding increase of absorption at 3280 A, suggesting a conversion into vit. A. The lipochrome content of young fish may apparently be increased when they are fed on a diet containing a typical green alga (Chlamydomonas). The pigment stored may be unchanged carotene or a substance showing similar absorption.
