【目的】了解杂交鳢在池塘养殖中的生长特性，为今后在广西推广养殖提供参考依据和技术指导。【方法】从广东引进杂交鳢鱼苗进行池塘养殖，每月采样测量其体长和体重，并每天测量池塘水温，在广西柳州地区开展一个生长周期的养殖试验。【结果】杂交鳢鱼苗经过7个月的池塘养殖，其产量达53256.0 kg/ha，成活率为90.6%；5~12月杂交鳢的体长均处于增长状态，月均增长1.1~7.4 cm，体长生长曲线与池塘水温变化曲线走势基本一致；5~12月杂交鳢体重也呈明显的增长趋势，月均增重16.2~178.2 g，且体重生长曲线的斜率较体长生长曲线更陡。【结论】杂交鳢在广西的池塘养殖效果良好，尤其在广西桂北和桂中地区可替代罗非鱼进行推广养殖。

[Objective]The growth characteristics of hybrid snake-head were analyzed to provide references for promoting pond culture in Guangxi.[Method]The fry of hybrid snake-head was imported from Guangdong Province and raised in pond in Liuzhou region of Guangxi for a growth cycle. The body length and body weight of fish samples were measured every month, and the water temperature was measured every day.[Result]After 7 months’ pond culture, the yield of adult fish approached to 53256.0 kg/ha, and the survival rate was 90.6%. From May to December of the year, the body length of hybrid snake-head grew with the average monthly growth of 1.1-7.4 cm. The growth curve of body length was almost the same with the change curve of water temperature. Over the same period, the body weight of hybrid snake-head also showed an obvious increment trend with the average monthly growth of 16.2-178.2 g. The slope of growth curve of body weight was steeper than that of body length.[Conclusion]These test results indicate that pond culture for hybrid snake-head is greatly feasible in Guangxi, and hybrid snake-head is more suitable than tilapia in northern and central region of Guangxi.
