摘　　要：选择2种发酵茶叶(祁门红茶和普洱茶)和4种非发酵茶叶(屏山炒青、霍山黄芽、黄山毛峰和龙井茶),以0.7%和1.4% 2种剂量分别添加在草鱼(Ctenopharyngodon idellus)饲料中、以1.0%和2.0% 2种剂量分别添加在斑点叉尾鮰(Ictalurus punctatus)饲料中,探讨了茶叶种类及添加量对2种鱼类鱼体主要生化成分影响。结果显示,对草鱼而言,各种茶叶基本都能显著提高鱼体干重率及鱼体蛋白含量,同时不同程度降低鱼体脂肪含量,但对鱼体灰分含量无显著影响,这些作用基本不受添加剂量的影响;对斑点叉尾鮰而言,霍山黄芽、黄山毛峰与祁门红茶能显著提高鱼体干物质含量,屏山炒青、龙井与祁门红茶能显著降低鱼体蛋白质含量,这些作用受到添加量的显著影响,同时各茶叶对脂肪与灰分含量无显著影响。结果表明,草鱼鱼体生化成分更容易受茶叶影响。In order to study the effects of tea on body composition of juvenile grass carp(Ctenopharyngodon idellus)and channel catfish(Ictalurus punctatus),two kinds of fermented teas(Qimen's black tea and Pu-erh tea)and four kinds of unfermented teas(Pingshan Chaoqing,Huoshan Huangya,Huangshan Maofeng and Longjing Tea)were used.For the six teas,two supplementation levels(0.7%,1.4%in grass carp diets and 1.0%,2.0%in channel catfish diets)were added into diet respectively.The results showed as follows:For grass carp,all kinds of teas significantly increased the contents of body dry matter and protein,and decreased body lipid contents at different degrees;the affect on the body ash contents and dosage was studied,and the tea dosage could not affect the results significantly.For channel catfish, Huoshan Huangya, Huangshan Maofeng and Qimen's black tea could increase the body dry matter significantly,and Pingshan Chaoqing,Longjing Tea and Qimen's black tea could reduce the protein contents significantly,and the their dosage could affect the results significantly.The contents of fat and ash were not affected significantly.The results indicated that biochemical composition of grass carp body was affected more significantly by teas.
