由于各种条件的限制,一些养鱼专业户无法建室外深水鱼类越冬池,而改用室内水泥池越冬。但由于管理方法不当,成败不一。为此,我们根据多年经验,提出几条鱼类室内越冬的管理方法。 1.保持室内安静无光的环境室内宜保持昏暗安静的环境,尽量减少越冬鱼的活动,以减少鱼体能量和池水中氧量的消耗。 2.保持低水温状态室内越冬鱼密度大,水不能结冰,水温宜保持
Due to various conditions, some specialized fish farming households can not build outdoor wintering ponds for deep-water fish, instead they use the indoor concrete pond for winter. However, due to improper management methods, success or failure. To this end, based on our many years of experience, we propose several methods of management of indoor winter fish. 1. To maintain a quiet indoor environment The indoor environment should be kept dark and quiet, minimize the activities of wintering fish, in order to reduce the energy of fish and water consumption of oxygen in the pool. 2. Maintain a low water temperature Indoor winter fish density, water can not freeze, the water temperature should be maintained
