1978年我们利用两个网箱进行四批培育大规格鱼苗试验,由8日龄养至3寸大的鱼种共4.68万尾,平均成活率达62％。在试验获得成功的基础上,79年又搞了三批,育苗7万多尾。两年为社队、水库提供了十多万大规格鱼苗。试验结果表明,利用网箱培育大规格鱼苗,成长快,成活率高,成本低,是加速鱼苗培育的好方法。
In 1978, we used two cages to carry out four batches of experiments to cultivate the large-size fry. From the age of 8 days to the end of the 3-inch large fish species, there were 46,800, with an average survival rate of 62%. On the basis of the success of the experiment, it has engaged in another three batches in 79 years and has raised more than 70,000 tails. Two years for the social teams, reservoirs provided more than 100,000 large-size fry. The experimental results show that the use of cages to cultivate large size fry, fast growth, high survival rate, low cost, is a good way to accelerate the cultivation of fry.
