摘要
利用温流水小水体养殖鲟鱼 ,初步试验结果表明 :放养规格在每尾长 10 - 12cm时 ,放养密度可达到80 - 90v/m2 ;当放养规格每尾长为 30 - 35cm时 ,放养密度以 5 0 - 6 0v/m2 为宜 ;鲟鱼的日均增重量随着个体的增重而增加 ;
The comparative experiment of breeding sturgeon with little water of heat running water initially shows that when the specification of the sturgeon is about 10-20cm,the fish culture density can be 40-45 v/m 2.And when the specification is about 30-35 v/m 2,the fish culture density reaches 25-30 v/m 2.The daily adding weight of sturgeon increase as they grow,the feedstuff coefficient also increase as the weight of the sturgeon increase.And the daily feedstuff should be confined between 1 43 and 2 09 of the sturgeon weight.
