“冬至”至“立春”,是淡水鱼种放养的“黄金季节”。因为这段时间气温低,水质比较稳定,鱼种体质坚实,鳞片紧密,拉网、运送、投放不易受伤,能提前适应周围新的环境条件,有利开春后迅速生长。冬季放养鱼种,必须把好以下“十关”。 一、鱼塘改造关。利用冬闲时节对小塘、浅塘、死水塘、漏水塘进行改造,条件较好的鱼塘也要进行修整,放干塘水,经太阳曝晒或冷冻后挖去过厚的淤泥,铲除杂草,加高加固塘埂。
“Winter Solstice” to “Spring” is the “golden season” for stocking freshwater fish species. Because of the low temperature during this period, the water quality is relatively stable, the species of fish are solid, the scales are close, pulling the net, transporting and putting are not easy to be injured, and can adapt to the new environmental conditions in the surroundings in advance, which is favorable for the rapid growth after the spring. Fish stocking in winter, we must put the following “ten off.” First, the transformation of fish ponds off. The use of winter leisure season on small ponds, shallow ponds, dead reservoirs, leaking ponds to be modified, the better the conditions of the fish ponds should be trimmed, put dry ponds, after sun exposure or freezing dredged thick mud, weed elimination , Heighten the pond 加 strengthening.
