Differences in carotenoid composition in the integument of Korean bittering, Cheilognathus signifer and bride bittering, Rhodeus ukekii which are Korean native fresh water fish were compared. Total ca rotenoid contents in the integument of wild Korean bittering was 2.11mg% and composed of 42.6% zeaxanthin, 12.1% diatoxanthin and 12.1% lutein epoxide which are predominant carotenoids and 10.3% cynthiaxanthin, 8.3% zeaxanthin epoxide, 6.4% lutein and 1.5% cryptoxanthin which are minor carotenoids. Total ca rotenoid contents in the integument of wild bride bittering was 4.99mg% during a spawning period but after the spawning period it was decreased to 4.17mg% and carotenoid composition of bride bittering during the spawning period was 46.7% zeaxanthin, 26.5% diatoxanthin and 12.3% lutein which are predominant carotenoids, and 6.2% zeaxanthin epoxide, 3.1% cynthiaxanthin, 2.9% cryptoxanthin and 0.7% canthax anthin which are minor carotenoids. These results indicated that the carotenoid composition of bride bittering during spawning period was very similar to that of Korean bittering and carotenoid composition of bride bittering after the spawning period was 30.5% diatoxanthin, 21.5% cynthiaxanthin and 16.8% zeaxanthin which are predominant carotenoids and 14.0% cryptoxanthin, 11.3% lutein and 3.4% can thaxanthin which are minor carotenoids, indicating that after the spawning period, the content of zeaxanthin was decreased while that of cryptoxanthin and cynthiaxanthin was increased as compared to that of the spawning period. Total carotenoid contents in Korean bittering and bride bittering was relatively higher than that in other species of cyprinidae whereas composition of the carotenoid was similar.
