| 摘 要： | 为研究高海拔山区稻田养殖禾花鱼的最优养殖模式,提高郴州高山禾花鱼养殖的标准化水平和规模化程度,试验在不影响禾花鱼品质和稻谷产量的前提下,综合考虑了苗种规格、养殖密度及投饵率3个关键因素,交叉设计了9个养殖模式试验组,通过每667 m2的禾花鱼产量和经济效益对不同模式进行比较评估。研究表明,9个试验模式均能当年养成商品鱼,其中9号试验组(放养规格48 g/尾、密度300尾/667 m2)和4号试验组(放养规格22.5 g/尾、密度400尾/667 m2这两个模式最佳,禾花鱼产量和产值均显著高于其他试验组,平均产量分别为23.7 kg/667 m2、21.7 kg/667 m2,平均纯利润分别为1198元/667 m2、1182元/667 m2。

| Abstract: | In order to study the optimal farming mode of cultivating fish in rice fields in high-altitude mountainous areas,and to improve the standardization and scale aquaculture of Chenzhou alpine carp,nine breeding model test groups were designed crossly in the experiment according to three key factors such:seed size,breeding density and feeding rate.The different models were evaluated through the yield per area and economic benefits.Results showed that all nine tesi qroups could grow commercial fish that year.Among them,the No.9 test group and No.4 test group were the best culture mode,the yield and output value were significantly higher than others.The fish of the No.9 test group was cultured with range specification of 48 g/tail and a density of 300/667 m2,its average yield per 667 m2was 23.7 kg and net profit per 667 m2was 1198 yuan.The fish of the No.4 test group was cultured with range specification of 22.5 g/tail and a density of 400/667 m2,its average yield per 667 m2was 21.7 kg and net profit per 667 m2was 1182 yuan. |
