Qualitative Water-soluble Vitamin Requirements of Tiger Puffer

Abstract

The qualitative requirements and deficiency signs of water-soluble vitamins were studied in tiger puffers Takifugu rubripes having mean body weight of 2.9 g. The qualitative requirements of tiger puffer for water-soluble vitamins indicate that the requirement of this species for vitamin B6 is lower than that of other fish species such as red sea bream, yellowtail, and Japanese parrot fish, while that for vitamins related to lipid metabolism, such as choline, nicotinic acid, pantothenic acid, biotin and inositol, is comparatively high. © 1994, The Japanese Society of Fisheries Science.
