摘要
长吻鮠幼鱼的总平均生态效率为11.44%,饵料系数7.41;在适宜的温度范围内,随水温上升,幼鱼体重增加.生态效率增大.在24.9℃以上的适温范围内,幼鱼生长快;密度对幼鱼的生长有明显影响,适宜的放养密度,幼鱼生长快,在本试验条件下.最适密度是12尾/m^2.
This papet reports following contents-. CD I 1. 41% is the total average ecologioal efficiency of the fish (L. Itmgerosl.rts); 12) there is significant correlation between the average ecological efficiency (E) of the fish and the water temperature (T), viz, E- 1. 381 3T- 21. 917 and (3) It is, obvious that density of the fish influence growth of the fish, and the optimum density is 12 fish per square metre.
