摘要 文章通过吉奥罗非鱼养殖试验,探讨和验证吉奥罗非鱼的优良经济性状,并获得了显著的效果。在21.45hm2的池塘中投放平均体重60g的吉奥罗非鱼鱼种48800尾,经192d养殖,吉奥罗非鱼平均体重为0.948kg/尾,产量为44.97t,平均产量为31.06t/hm2,总产值为32.4万元,获利7.65万元,经济效益显著。试验表明,吉奥罗非鱼集成了吉富罗非鱼生长速度快,奥尼罗非鱼雄性率高、抗病力强等优点,适合于不同地区、不同环境的池塘养殖,推广养殖前景广阔。 The paper was conducted to study the effect of culture experiment of Ji'ao tilpia and to test its economic characters. All 48 800 juveniles were put in a pond of 21.45 hm^2, with average weight of 60 g. The average weight was 948 g after being breed for 192 days. The economic characters increased significantly as a result of total production of 44.98 t, average production 31.06 t/hm^2, and profit 76.5 thousand RMB. It demonstrated that Ji'ao tilpia inherit high growth rate of Fuji tilpia and high male sex rate and strong anti-disease of Nile tilpia. It can be cultured in different pond in various'area and a promising species for spreading
