The diet of the halibut and intensity of feeding, in relation to the vitamin A potency of the liver oil

Abstract

The diet of the halibut contains no outstandingly rich source of vit. A. No correlation could be established between intensity of feeding, as measured by glycogen content, and the vit. A potency of the oil. Further evidence was obtained that in general the livers of older fish afford a more potent oil than those of younger fish.
