After 2 months, the samples of skin, scale, head and fm ray of the carps were selected for the subsequent analysis of determining their total carotenoid contents and the absorbance values, so the above solutions were evaporated to dryness, and then were measured by the thin layer chromatography. The results show that the spectrum of total pigment of koi carp had two absorption peaks in visible light (454 nm and 470 nm). The growth rate, weight gain and specific growth rate of red-white of koi carp fed with 1.0 g/kg β-carotene tended to be obviously higher than the control group (P.05), while the FCR of groups fed with 1.0~2.5 g/kg β-carotene was significantly lower than the control group (P.05). The colouring of red-white and red region in koi carp was the best at 1.5~2.0 g/kg β-carotene in diet, while the n-carotene added in the diets did not have any effects on total carotenoid concentration of skin/scale of white region. The n-carotene mainly deposited in skin and fin ray. And it mainly transformed into astaxanthin in koi carp.

While early studies focused on the potential roles in health and disease of provitamin A carotenoids, such as b-carotene, research over the past decade has provided a framework for our understanding of the functions of non-provitamin A carotenoids such as lycopene, especially in regards to its association with a reduced risk of a number of chronic diseases, including cancer.

It was showed that pectenolone and pectenoxanthin were all found in Gonads, hepatopancreas, mantle and gill, among of them, ovary, hepatopancreas and gill possessed more carotenoid than other tissues, but no carotenoids were found in the white muscles of Yesso scallops. Hepatopancreas contains a variety other carotenoids some kind of other not identified beside pectenolone and pectenoxanthin.
