To know a physiological role of vitamin in the development of fish eggs, changes in the con-tents of ascorbic acid, pantothenic acid, biotin, niacin and vitamin B6, and activities of glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) in developing rainbow trout eggs were determined.<br> The ascorbic acid content rapidly decreased by half level on third day after fertilization, thereafter the vitamin tended to decrease during development. The sac fry, when a substantial amount of the yolk had disappeared, retained the ascorbic acid and was about one fourth of that of the initial eggs. The amounts of thiamine, pantothenic acid and biotin were reduced by half during the course of development, while niacin content tended to increase after hatching. The amounts of vitamin B6 decreased by about 45% during the course of the development. Some variation of the composition were found: the concentration of pyridoxal decreased appreciably, while those of pyridoxal 5'-phosphate, pyridoxamine 5'-phosphate and pyridoxamine increased in the course of development.<br> The activities of GOT and GPT were very low in the early stages of development. After hatching, the activities of the vitamin B6 enzymes increased greatly.
