摘要
用亚洲六须鲶作母本和鲶鱼作父本进行远缘杂交,获得生长速度近于母本，高于父本，肌肉营养成份含量高于亲本的杂交种。杂交鲶的体色、体高／体长、头长／体长、须数界于亲本之间；而鳃耙数、口裂／头长、肠长／体长大于亲体。
Using remote kinsfolk crossbreeding method with Asian catfish(♂) and catfish(♀) asparents,we gained the first generation hybrid whose growth rate comes to ists maternal fish and muscle quality is improved. According to the results of 12 measured characters, the hybrid body colour, ratios of head length to body length and feeler numbjers are sitated between its parents. Its baker number, ratios of mouth opening to head length, ratios of intestine length to body length improve, which is believed to promote feeding and degestion of hybrid fish. The growth rate of individual fish is signifcantly higher than catfish and the muscle nutrient content is also higher than that of its parents.
