冬季并塘后到翌年放养夏花前,大部分鱼种池将有半年左右的空闲期,对其进行综合利用,可以提高鱼种池的利用率。下面介绍冬闲鱼种池的两种利用方法。 1.养成鱼。利用冬闲鱼种池可以养一季成鱼。由于养殖期限较短,温度较低,应采用以下技术:(1)提早放养,即在鱼种并塘后即行放养,以充分利用生长期。放养量以最大水深2米左右计算,一般每亩放鱼125～150公斤,其中鲢占40％,鳙占10％,鳊、草鱼占30％,鲤、青鱼占20％。放养鱼种要大规
Most of the fish species ponds will have an idle period of about six months after pond ponds are collected in winter and ponds until the following year, and their comprehensive utilization can increase the utilization rate of pond species. Here are two kinds of winter leisure fish species pool use. 1. develop fish The use of winter leisure fish ponds can raise a season of adult fish. Due to the short duration of cultivation, the temperature is low, the following techniques should be used: (1) early stocking, that is, stocking and ponds after stocking to take full advantage of the growing season. Stocking to the maximum depth of about 2 meters, the general release of fish per acre 125 to 150 kg, of which silver carp accounted for 40%, accounting for 10%, 鳊, grass carp accounted for 30% carp, herring accounted for 20%. Stocking species should be large
