俗话说“春放鱼种鱼发瘟,冬放鱼种长三分”。实践证明,冬至至立春是投放鱼种的最佳时机。原因有三:一是此时鱼种壮、鱼鳞紧,适应能力强。二是水温低,鱼活动力弱,捕捞和放养过程中成活率高。三是免去并塘越冬的麻烦,使鱼种较早地得到疏散精养,促进早春生长。1.鱼池改造利用冬闲? As the saying goes, “Spring fish stocking fish blast, winter fish species long third.” Practice has proved that the winter solstice to the beginning of spring is the best time to put fish species. There are three reasons: First, fish species at this time, fish scales tight, adaptable. Second, the water temperature is low, the fish activity is weak, high survival rate in the process of fishing and stocking. The third is to remove the trouble of pond and wintering, so that the fish species can be evacuated and intensively cultivated to promote early spring growth. 1.
