在养殖条件下，通过70 d的生长实验研究了养殖密度和投饵率对1龄大鲵（ Andrias davidiaus）摄食与生长的影响。养殖密度实验设40、70、100、130、160尾/m2五个组，投饵率实验设1.00％、1.50％、2.00％、2.50％、3.00％五个组，实验结束以增重率（ WGR）、特定生长率（ SGR）、肥满度（ CF）、饵料系数（ FCR）为依据，综合评价养殖密度和投饵率对大鲵生长的影响。结果显示：1龄大鲵适宜养殖密度为70尾/m2，该组特定生长率显著高于160尾/m2组；1龄大鲵适宜投饵率为2.00％，该组增重率和特定生长率显著高于3.00％组。

The effects of stocking density and feeding rate on the growth and ingestion of 1 year old giant salamander on the conditions of industrial aquaculture were studied.A 70 -days experiment was conducted in this study.Five daily feeding rates were designed at 1.00%, 1.50%, 2.00%, 2.50%, 3.00% of the total body weight.And five stocking densities were designed at 40, 70, 100, 130, 160 tail /m2.At the end of the feeding trial, the giant salamander were weighted and measured by batch for the determination of weight gain rate (WGR), special growth rate (SGR), condition factor ( CF) and feed conversion ratio ( FCR) which we used to comprehensive evaluation the effects of stocking density and feed -ing rate on the growth of giant salamander.The results showed that: The suitable stocking density of 1 year old giant sala-mander was 70 tail/m2 , special growth rate of which was significantly higher than that of the group of 160 tail/m2; The suitable feeding rate of 1 year old giant salamander was 2.00%, weight gain rate and special growth rate of which was sig-nificantly higher than the group of 3.00%.
