新疆远离海洋,大河、湖泊又少,要大量供应市场商品鱼;必须充分利用水库的水面,加速发展渔业生产.水库养鱼要实行轮捕轮放,投放大规格鱼种,才能显著提高鱼产量.没有凶猛性鱼类的水库,鱼种规格达到2.5—3寸即可;有凶猛性鱼类的水库,鱼种规格需达3.5—4寸.规格小的鱼种,游泳能力差,会被肉食性的鱼类吃掉;其抗逆力也弱,越冬期间常不耐寒冷而死亡.投放大规格鱼种,可避免上述损失,显著提高成活率,鱼产量也将相应增加.
Xinjiang far away from the sea, large rivers, lakes, and a large number of market supply of fish to be large; must make full use of the reservoir surface to accelerate the development of fishery production. Reservoir fish to implement the wheel catcher and put large fish species, in order to significantly increase fish production No ferocious fish reservoirs, species size of 2.5-3 inches can be; there are ferocious fish reservoirs, species specifications need to reach 3.5-4 inch species of small species, swimming ability is poor, will be Carnivorous fish eat; its resilience is weak, often cold and cold during winter death. Put large-scale species of fish, to avoid the above losses, significantly improve the survival rate, fish production will also increase accordingly.
