水库小体积网箱试养证明,长吻鱼种适于网箱养殖和水库生态环境,而且生长快、饲料系数低、成活率高。长吻脆鱼种经45天饲养,由始均重6.97g长至20g以上,相对增重率达288%左右,成活率高达97%-100%。投喂率与水温关系密切。随投喂率增大,长吻生长加快,但饲料系数逐渐增大,当水温为26-30℃时,适宜投喂率为4%,水温为21-26℃时,适宜投喂率为2%。
Trial trial of small size cages in the reservoir proves that the long-legged fish species are suitable for the cage culture and the reservoir ecological environment, and grow fast with low feed coefficient and high survival rate. The long-billed fish species reared for 45 days grew from 6.97 g to 20 g above, with a relative weight gain rate of about 288% and a survival rate of 97% -100%. Feeding rate and water temperature are closely related. With the increase of feeding rate, the growth of long kisses accelerated, but the feed coefficient increased gradually. When the water temperature was 26-30 ℃, the suitable feeding rate was 4%. When the water temperature was 21-26 ℃, the suitable feeding rate was 2 %.
