【摘要】 研究了不同放养密度下黄鳝的生长状况。结果表明:不同放养密度对网箱养殖黄鳝的体重和体长的增长有显著的影响。黄鳝在密度35尾/m2的网箱养殖条件下体重增长速度较快,其最终体重、增重率、增长率显著高于黄鳝最低密度组15尾/m2和黄鳝最高密度组90尾/m2。实验表明密度过低或过高都不利于黄鳝的生长,黄鳝网箱养殖存在着一个最适放养的密度。高密度养殖黄鳝生长离散较大,大小规格不齐;密度过低时,黄鳝摄食效果差,生长发育也会受到较大的影响。更多还原

【Abstract】 The present research studied on,the growth of Monopterus albus in different densities in the conditions of cage culture.The result indicated that density has significant impact on length,weight and growth ratio of M.albus.Group of thirty-five fish per quarters grow faster than other groups.High densities and too lower prevent the growth of the fish.The study found that the most proper density was range from 35 to 45 fish per quarter.更多还原
