Abstract

Carotenoid pigments in the integuments of five species of fresh water fishes, piranha, bluegill, flamingo cichlid, red devil, and formosan snakehead were investigated. Tunaxanthin (a mixture of tunaxanthin A, B, and C) was found in all four species belonging to the superorder acanthopterygii except piranha belonging to the superorder anotophysi, and the fraction was predominant in both formosan snakehead (44%) and bluegill (ca. 77-83%). The principal carotenoids of beautifully red colored nattereri piranha which were reared with gold fishes as staple diet, were astaxanthin (ca. 55%), α-doradexanthin (ca. 17%), and 3'-epilutein (ca. 14%).In contrast with the above case, different individuals of the same species whose color was not so beautiful as the former and were reared with bitterlings, contained 3'-epilutein (ca. 35%) as major carotenoid, and the amount of astaxanthin of the latter was thirteenth of that of the former. This is the example that a considerable effect of culture condition (mainly diet) on amount of individual carotenoid was observed in the same species of fish. Canthaxanthin (ca. 77%) in red devil, lutein (ca. 20%) and 3'-epilutein (ca. 16%) in flamingo cichlid were identified as their major pigments.
