摘要
对饲料中添加不同含量的虾青素与不同饲养时间对金鱼体色的影响进行了研究。结果表明：不同虾青素添加量与不同饲养时间对金鱼的色素沉积有着极为显著的影响。随着饲料中虾青素含量的逐渐增加，在同—饲养时间段内其每克千鱼体重所含的色素量也逐渐增加。无论是对照组还是各试验组，随着饲养时间的延长，每克干鱼体重所含的色素量呈增加趋势。在肚15d这段时间内，鱼体单位干重的色素积累速率是随着虾青素的添加量的增加而加快的。对于组内鱼体而言其色素积累速率在0~15d和46-60d两段时间内较快，而在16-45d的时间段内相对较漫。
The effects of contents and feed time of astaxanthin on coloring performance of Carassius auratus were studied in this paper. The results showed that the astaxanthin ratio in feed and the different feed time have highly effect on the pigment sexiiment of Carassius auratus. The pigment content in dry fish was improved with increasing astaxanthin concentration in feed in the same feed time. For both the control and the test groups, the pigment contents in the unit dry fish showed increase trend with prolonging feed time. Within 0~15 days, the speed of pigment accumulate in the unit dry fish was improved with increasing the astaxanthin ratio in feed. For the samples in same group, the speed of pigment accumulate in the unit dry fish increased fast in the periods of 0~15 days and 45-60 days, while increased slowly during 15-45 days.
