摘　　要：[目的]了解草鱼♀×鳡♂杂交F1代的养殖性状。[方法]对草鳡杂交F1代的食性、生长和抗病性状进行分析。「结果」草鳡杂交F1代的消化器官与草鱼相似,但肠管较短,是以草食为主的杂食性鱼类。杂交F1代的生长比草鱼快,体长与体重的关系式为:W=0.015 2L2.946 7,呈匀速生长。杂交F1代对草鱼出血病有较强的抗病力。[Objective] In order to understand the breeding traits of F1hybrid（ C. idellus ♀ × E. bambusa ♂）. [Method]The feeding habits,growth and resistance properties of hybrid F1 were analyzed. [Result] The results showed that the hybrid＇s digestive system are similar to grass carp,but short bowel. The hybrid F1 is herbivorous-omnivore-fish. The hybrid F1 growth is faster than grass carp. The relationship between the body length and weight can be expressed as W = 0. 015 2L2. 946 7. It belongs to the type of uniform growth. The hybrid F1 were better than grass carp in hemorrhage disease resistance.
