摘要
该试验进行了以虹鳟鱼为主养的池塘套养不同密度鲟鱼的试验。在投喂相同虹鳟鱼饲料量的情况下,以单养虹鳟鱼池塘作为对照,按照试验池塘50尾、100尾、200尾三个不同密度进行套养鲟鱼试验。经过230d的养殖,通过对对照池塘和试验池塘的成本和收益进行比较分析,试验池鲟鱼的产量分别达到35kg、67kg、86kg;鲟鱼的投入产出比分别达到1:2.00,1:1.92,1:1.23。试验结果表明:虹鳟鱼池塘套养鲟鱼的养殖模式是可行的;当虹鳟鱼套养鲟鱼的比例不高于5%时,套养池塘的产量高,经济收益好。
This experiment taken rainbow trout as the based population and raised with different density of sturgeon. The control group was fed only rainbow trout, while the other three groups were added 50,100 and 200 fries sturgeons, respectively. After 230 days feeding trial,compered with control group,the yield of sturgeon reaches 35kg, 67kg and 86kg, respectively; the input--output ratios were 1-2;1..1.92 and 1..1.23, respectively. The results showed that inter--cropping of sturgeon is applica- ble and the optimal ratio of rainbow trout to sturgeon is not higher than 5 %.
