鲫是我国最普通的养殖鱼类,但传统上多在池塘中与鲤、草鱼、鲢、鳙混养,鲫作为非主体鱼生长受到抑制,产量较低。为提高鲫养殖效益,我局利用960m2石砌池进行主养彭泽鲫试验,发现鲫的群体增重倍数基本与鲤相当,存活率高,饲料系数和饲料成本与以往养殖 Crucian carp is the most common cultured fish in China, but traditionally polyculture with common carp, grass carp, silver carp and bighead carp in the pond, the growth of crucian carp as a non-main body is inhibited and the yield is low. In order to improve the efficiency of crucian carp breeding, the Bureau of 960m2 stone pond was mainly used to carry Pengze crucian carp test. It was found that the population multiplication rate of crucian carp was basically equivalent to that of common carp, with high survival rate, feed coefficient and feed cost
