【摘要】 通过使用钝顶螺旋藻 (Spirulinaplatensis)喂养锦鲤 (Cruciancarp)试验 ,探讨了不同含量的螺旋藻干粉配合饵料以及活藻对锦鲤体色和生长的影响。试验结果表明在相同水温、光照和投喂量的条件下 ,随着螺旋藻干粉投喂量的增加 ,锦鲤体色越鲜艳 ,体重、体长也相应增加 ,其中鲜活螺旋藻对其体色、体长、体重影响最大。还探讨了体色定量测定方法。其结果显示 ,鱼鳞的黑色素细胞数和红色素丙酮抽提液光密度值随着饵料中螺旋藻含量提高而增加。这表明应用黑色素细胞计数法和红色素丙酮抽提液光密度测定法能客观反映锦鲤体色鲜艳度 ,为今后客观评价锦鲤体色奠定了基础更多还原

【Abstract】 The effects of the feed with different amount of the dried Spirulina platensis and fresh Spirulina platension on the growth and body color changes in Crucian carp have been studied.The result shows that the more the amount of Spirulina platensis in feed is, the longer and weightier the fish will be, and the brighter the body color of the fish will become. Feeding with fresh Spirulina platensis would make a better effect on increasing fish color and body weight than feeding with the Spirulina pander feed. The methods of quantitative measuring body color have also been studied. When the amount of Spirulina platensis in feed increased, black pigment cells and the OD value of the red pigment abstract with acetone in the fish scale are promoted. So it is realistic to count the black pigment cells and to analyse the OD value of the red pigment for distinguishing the fish color grades.更多还原
