将夏花鱼种(寸子)培养成规格在13—17cm以上、体重达到50g的鱼种即为大规格鱼种。大规格草鱼种培育因病害频繁而影响其成活率、个体规格和产量,所以要获得草鱼种培育高产和大规格须掌握其技术要领。现介绍以草鱼为主的大规格一龄鱼种高产培育方法如下: 一、施足基肥,加强水质调节。草鱼夏花入池前施入粪尿400～50ckg/亩,使池水透明度在30—40cm。入池时,水深约70cm。以后每周加一次水,每次加深10cm,进出水口用密网布过滤。到鲢鳙入池
The summer flowers species (inch) cultured to specifications in 13-17cm above, weighing 50g species of fish is the large size of species. Large size grass carp breeding due to frequent disease and affect the survival rate, individual specifications and production, so to get the grass carp cultivate high yield and large format to master the technical essentials. Are introduced to grass-based large-scale large-scale species of fish breeding methods are as follows: First, the application of foot-based fertilizer to enhance water quality regulation. Grass carp summer flowers into the pool before the application of excreta 400 ~ 50ckg / mu, so that the transparency of water in the 30-40cm. Into the pool, the water depth of about 70cm. After a weekly increase in water, each deepening 10cm, out of the outlet with a dense mesh filter. To silver carp into the pool
