摘要
2004～2006年在梧州市桂江采用可抵抗洪水冲击的船型网箱进行养殖斑鳜试验,饲养时间约500d。结果2个试验网箱共产鱼476kg,平均每立方米产量19.8kg,增重倍数为8.8,养殖成活率为93.9%,饵料系数为5.2,投入产出比为1∶2.05。试验结果表明,江河网箱养殖斑鳜可行,有开发前景。
From 2004 to 2006, net-cage culture of Siniperca scherzeri experiment was carried out in Guijiang River of Wuzhou, and ship type net-cages were applied to prevent the flood impacting, the feed period of Siniperca scherzeri was about 500 days. The results showed that the total yield of Siniperca scherzeri in two net-cages was up to 476kg, and the yield per cubic meter was 19.8kg, which was 8.8 times increasing, and the culture survival rate was 93.9 %. Moreover, the feed coefficient of adult Siniperca scherzeri was 5.2, and the ratio of input and output was 1 ： 2.05. It indicated that the culture techniques of Siniperca scherzeri in Xijiang River with net-cage was practicable, and it could be extended.
