1999年5月~2000年4月 ,对垸内胜利湖和垸外新河的8只网箱养殖加州鲈效果进行了比较。结果表明 ,外河4只网箱养殖加州鲈平均净单产28.9~30.5kg/ ,成活率86.0 %~91.2 %,增重倍数14.5~19.0 ,依次比内湖4只网箱的净产量(22.4~24.7kg/ )、成活率(81.0 %~85.6 %)、增重倍数(12.0~15.2kg/ )分别高4.7~6.1kg/ 、4.0%~5.6 %、2.4~3.8kg/ ;此外 ,相同水域不同放养密度的产量、成活率、增重倍数也有明显差别。
From May 1999 to April 2000, the effects of California cage perch on eight cage aquaculture in Shengli Lake embankment and embankment outer river were compared. The results showed that the average net yield of sea crab perched in 4 cages in outer rivers was 28.9-30.5kg /, the survival rate was 86.0% -91.2%, and the weight gain rate was 14.5-19.0. The net production of 4 cages per square lake was 22.4-24.7kg /), The survival rate (81.0% ~ 85.6%), weight gain multiples (12.0 ~ 15.2kg /) were 4.7 ~ 6.1kg /, 4.0% ~ 5.6%, 2.4 ~ 3.8kg / The yield, survival rate, weight gain times are also significantly different.
