六年来,绍兴在网箱培育鲢鳙鱼中,由于饲养鳙鱼效果不及鲢鱼显著,造成外荡放养比例失调,影响了淡水鱼产量的增长速度。绍兴市水产局水产技术推广站,为了解决这个技术问题,从1979年起开始从事网箱培育鳙鱼技术的研究工作,1981年进行了网箱主养鳙鱼的试验,已初获成功。试验证明,在外荡水域中进行网箱主养鳙鱼(放养量占总放养量的80～90%)是可
In the past six years, Shaoxing cages silver carp and bighead carp in net cage. Due to the poor rearing of carp, the silver carp is notable, resulting in the imbalance of external stocking and affecting the growth of freshwater fish production. In order to solve this technical problem, Shaoxing Aquatic Fisheries Technology Promotion Station has been engaged in research on the cultivation of catfish technology since its establishment in 1979. In 1981, it conducted a trial of catfish with its main cage, which was initially successful. Tests show that in the outer ponds for the main cage fish carp (stocking the total stocking volume of 80 to 90%) is
