用网箱囤养越冬鱼种,池塘占用面积小,鱼种集中,便于饲养管理,成活率高,是鱼种越冬的一种好方法。1.网箱设置放置网箱的地点应选择在避风向阳、水质清新、溶氧量高、无工业污染和有机废水流入的湾汊水域,水面要宽敞,水底要平坦,水深在3米以上,且水位波动不大,最好有微流水。网箱应选用六面封闭的沉下式网箱,一般长7米、宽4米、高2米,网目大小要与放养的鱼种规格相适应,如放养规格为10~14厘米的鱼种网目为2.3~3厘
Cages hoarded winter species, ponds occupy a small area, concentrated species, easy feeding and management, high survival rate, is a good way for winter species. 1. Cage settings Cages placed at the location should be chosen in the shelter from the sun, fresh water, dissolved oxygen high, non-industrial pollution and organic waste water inflow Bayan waters, the water should be spacious, the water should be flat, the water depth of 3 meters, And the water level fluctuations, the best micro-water. Cages should be closed on all sides of the closed cage, usually 7 meters long, 4 meters wide, 2 meters high, mesh size and stocking species specifications to adapt, such as stocking specifications for 10 to 14 cm of fish The net is 2.3 ~ 3%
