Fat metabolism in fishes

Abstract

In feeding expts. with eels under various environmental conditions, a low-fat diet produced no detectable change. With a high-fat diet the depot fat was modified, ingested fat being deposited with unchanged proportions of the various acids. Hydrogenation occurred. Higher temps. produced slightly more saturated fats on both diets, and on the high-fat diet caused less modification of the depot fat in spite of increased food intake. The mechanism controlling depot fat composition was apparently accelerated by rise of temp. Salinity had no effect with a low-fat diet.
