1 泥鳅 泥鳅对水温的变化相当敏感,当水温降至5℃以下时,泥鳅便钻入淤泥中越冬,越冬期长达2~3个月。越冬期要做好防寒、保温工作,保持水深1.5m以上,使水温在2℃~8℃之间。稻田养殖的泥鳅在越冬前应将泥鳅集中于鱼溜内,并用稻草铺在鱼溜上,泥鳅便会潜入鱼溜底部的淤泥中越冬。2育珠蚌 水温降到10℃以下,河蚌的心脏博动频率小,滤水量、耗氧量、摄食量明显减少,几乎停止生长。此时不宜再向池中施有机肥,
1 Loach loach is quite sensitive to changes in water temperature, when the water temperature dropped below 5 ℃, loach will drill into the mud in the winter, wintering period of up to 2 to 3 months. Overwintering to do cold, heat work, keep the water depth 1.5m above, so that the water temperature between 2 ℃ ~ 8 ℃. Loach farmed in paddy before the winter should be concentrated in the fish slip loach slip, and shop with the straw in the fish slipped, loach will sneak into the bottom of the fish slippery wintering. 2 Pearl water temperature dropped to below 10 ℃, mussel heart frequency of small Bo, water filtration, oxygen consumption, food intake decreased significantly, almost stopped growing. At this point should not be re-applied to the pool of organic fertilizer,
