摘要: 研究了不同藻源对血艳红慈鲷(Copadichromis trimaculatus)体色以及部分免疫指标的影响。试验配制4种饲料,分别为不添加藻粉的基础组和添加藻粉的盐藻组、裂壶藻组及小球藻组,添加水平均为1%。将平均体重为(9.39±0.55) g的180尾血艳红慈鲷,随机分为4组,每组3次重复,每次重复设置15尾鱼,进行为期45 d的摄食生长试验。结果表明,盐藻组皮肤和鳍条中总类胡萝卜素含量显著高于其他3组(P<0.05),裂壶藻组对血艳红慈鲷体表a*的增加有着明显的促进作用(P<0.05)。盐藻组可显著提高血艳红慈鲷肝脏中的酸性磷酸酶(AKP)、碱性磷酸酶(ACP)和谷丙转氨酶(GPT)的活性(P<0.05),而各组试验鱼血清中谷丙转氨酶和谷草转氨酶(GOT)的活性均无显著差异,空白组含量较高。盐藻组和裂壶藻组对血艳红慈鲷体色有着明显的改善作用,盐藻组可提高其肝脏的免疫机能。

Abstract: : A feeding trial was conducted to evaluate the effects of different algal sources on skin color and partial immune index of cichlids. Four experimental diets were formulated to add Dunaliella salina,Schizochytrium Limacinum and Chlorella vulgaris with 1% algal,and the basal diet(without algal).Each diet was randomly assigned to triplicate groups with 15 Copadichromis trimaculatus (approximately 9.39±0.55 g) which were cultivated for 45 days. The results showed that the concentration of carotenoid in the skin and fin of fish was significantly higher in the diet of adding Dunaliella salina than others(P<0.05). The diet of adding Schizochytrium Limacinum could significantly increase the a*(P<0.05). Moreover,the diet of adding 1% Dunaliella salina could significantly increase the activity of acid phosphatase(AKP),alkaline phosphatase (ACP),and alanine aminotransferase(GPT) in the liver of cichlids(P<0.05),and the activity of GPT and aspartate aminotransferase(GOT) has no significant difference in the serum of all tested fishes. In conclusion,the diet of adding Dunaliella salina and Schizochytrium Limacinum was effective in modifying the body color of Copadichromis trimaculatus and the former could improve the immune function of the liver.

Key words: Copadichromis trimaculatus, body coloring, immunity index
