College of Life Sciences， Jianghan University， Wuhan， Hubei  430056; 2. Sihui Aquatic Science and Technology Development Co. Ltd.， Wuhan， Hubei 430065）Abstract [Objective] In order to understand the breeding traits of F1 hybrid （C. idellus ♀×E. bambusa ♂）. [Method] The feeding habits， growth and resistance properties of hybrid F1 were analyzed. [Result] The results showed that the hybrids digestive system are similar to grass carp， but short bowel. The hybrid F1 is herbivorousomnivorefish. 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.Key words  F1 hybrid （C. idellus ♀×E. bambusa ♂）; Feeding habits; Growth; Grass carp hemorrhage disease基金項目 武汉市科技计划项目（2013021001010464） 。
