随着气温的不断回升,各地温度明显比前段时间要高,闷热天气会越来越多,因此,水产养殖病害的发生也会随之增多,现介绍几点注意事项,供水产养殖户参考。增加水体溶氧。有增氧设备的可在晴天中午坚持开启增氧机2小时以上,遇到阴雨天或天气突变要及时开启增氧机。如无增氧机的可采用潜水泵在池内打循环水(时间在下午3时前,切忌在傍晚进行),增强水体的对流与交换,或备好增氧剂,视天气情况提前施用,以防缺氧引起水质突变和泛池。 As the temperature continues to rise, the temperature is obviously higher than some time ago, the hot weather will be more and more, therefore, the occurrence of aquaculture diseases will also increase, are the points to note, aquaculture farmers reference. Increase dissolved oxygen in water. Aerobic equipment can be maintained in the sunny noon to open the aerator more than 2 hours, encountered rainy days or sudden weather changes to promptly open the aerator. If there is no aerator can be submersible pump playing in the pool circulating water (time before 3 o’clock in the afternoon, should not be carried out in the evening), enhance the convection and exchange of water, or prepare aerosols, depending on weather conditions in advance to Anti-hypoxia caused by water quality mutations and pan-pool.
