Abstract
IN previous communications1,2 the relationships between the contents of pantothenic acid, riboflavin, niacin, vitamin B12 and biotin, and the reproductive cycle of ovaries in cod were reported. Pantothenic acid was found to show a unique relation, the values being very high in ovaries from juvenile fish and from mature fish in the first stages of regeneration. The average values for juvenile, maturing and ‘ripe’ ovaries were respectively 234, 115 and 30 µgm. pantothenic acid per gm. fresh weight. Riboflavin, niacin and biotin did not show variation, while vitamin B12 showed a definite though slight decrease during the regenerative cycle. This finding for vitamin B12 was verified in later investigations.
