摘　　要： 比较了饵料台水上与水下两种设置方法、水葫芦栽培与不栽培两种水质改良方法及网箱与水泥池两种饲养环境对稚鳖培育增重率、成活率、饵料系数的影响。设置在水上比水下的稚鳖增重率、成活率分别提高７５．０１％、１６．６０％，饵料系数下降４４．７３％；水葫芦栽培比不栽培的增重率、成活率分别提高４４．１５％、２５．２５％，饵料系数下降４２．５４％；网箱比水泥池培育增重率、成活率分别提高１３７．７２％、１７．６５％，饵料系数下降６．８９％。 This paper dealt with the comparison between larval soft-shelled turtle culturing in cage and culturing in cement pool. And effect of water hyacinth and different kinds of food-deck on turtle culture were also reported. The results showed follow: The body-weight increment rate, survival rate were 44.14-137.72%; 16.60-25.25% respectively higher for those culturing in cage, culturing with water hyacinth, culturing with up-water-food-deck(test groups) than for those turtle culturing in cement pools, culturing without water hyacinth, culturing down-water-food-deck (control groups), And the food coefficients for the test groups were lower 6.89-44.73% than those for control groups. And water quality in the test groups were evidently improved.
