摘　　要：通过在基础日粮中添加卵磷脂、维生素E、鱼油或附加动物饵料(黄粉虫、中华圆田螺肉)等营养源,研究了不同营养源或其组合对圆口铜鱼(Coreius guichenoti)亲鱼生长与性腺发育的影响。实验分A、B、C三组进行:A组添加鱼油、卵磷脂、黄粉虫,设置4个实验组(A1、A2、A3、A4);B组添加维生素E,设置2个实验组(B1、B2);C组添加卵磷脂、维生素E和螺肉,设置2个实验组(C1、C2);另对应设置3个对照组(A0、B0、C0,仅投喂基础日粮)。结果显示:经过数月的养殖(A、B组300 d,C组240 d),各试验组亲鱼生长总体优于对照组,但差异不显著;雄鱼性腺均能发育成熟,成熟率达到100%;而雌鱼性腺发育则存在较大差异。在基础日粮中单独添加2%卵磷脂组(A2),雌鱼成熟率达到16.13%;同时添加2%卵磷脂、5%鱼油、25%黄粉虫组(A4)雌鱼成熟率19.13%,均高于对照组(A0)的8%。添加0.1%维生素E组(B1)、0.2%维生素E组(B2)的雌鱼成熟率分别为16.22%、21.21%,均高于对照组(B0)的6%。添加0.2%维生素E和2%卵磷脂组(C1),雌鱼成熟率为66.67%,高于对照组(C0)的30.02%。添加0.2%维生素E和2%卵磷脂同时投喂25%螺肉组(C2),亲鱼成熟率为55.01%,显著高于对照组(C0),但低于未添加螺肉组(C1)。结果表明:在基础日粮中单独或组合添加卵磷脂与维生素E投喂圆口铜鱼亲鱼可以显著提高雌鱼成熟率。Different formulated diets supplemented with lecithin,vitamin E,fish oil,Tenebrio molitor(L.)or Cipangopaludina cathayensis meat were used to study the effects of foodstuff sources on the gonadal development of Coreius guichenoti.The experiment was divided into three groups:group A,group B and group C.Group A had four experimental groups(A1,A2,A3 and A4),fed formulated diets supplemented with fish oil,lecithin or Tenebrio molitor(L.).Group B had two experimental groups(B1 and B2),fed formulated diets supplemented with vitamin E.Group C had two experimental groups(C1 and C2),fed formulated diets supplemented with lecithin,vitamin E or C.cathayensis meat.In addition,three control groups(A0,B0,C0,only fed the basal diet were set.After several months of feeding(300 days of groups A and B,240 days for group C),the growth of parent fish of each experimental group was better than that in the control group.However,the difference was not significant.The gonads of all the male fish could mature,and the maturation rates were 100%.However,the female fish gonadal development of all the experimental groups were quite different.When 2%lecithin was added to the basal diet(group A2),the maturity rate of female fish reached 16.13%.The maturity rate of female fish in group A4 was 19.13%,higher than that in control group A0(8%).The maturity rates of female fish supplemented with 0.1%(group B1)and 0.2%(group B2)vitamin E were 16.22%and 21.21%,respectively,which were higher than that of the control group B0(6%).In the group supplemented with 0.2%vitamin E and 2%lecitin(C1),the maturation rate of female fish was 66.67%,which was higher than that in the control group C0(30.02%).The maturation rate of female fish in the group C2(adding 0.2%vitamin E,and 2%lecithin,25%C.cathayensis meat)was 55.01%,which was significantly higher than that in the control group C0 but lower than that in the group C1 without adding C.cathayensis meat.In conclusion,formulated diets supplemented with lecithin and vitamin E alone or in combination could signific
