由中国科学院水生生物研究所和武汉农药厂联合筛选、开发的鱼池化学增氧剂——“鱼浮灵”是一种很好的泛塘急救药物,它不仅作用快,而且使用和运输也方便。目前,“鱼浮灵”有速效和长效两类剂型。速效型放氧较快,4～6小时内在水中放氧达最高值,适用于急救,长效型粒度较大,放氧慢,适用于予防和改善水质。“鱼浮灵”在鱼池中使用的安全浓度为50毫克/升,使用后不会影响鱼的质量,也无残毒。使用方法有遍撤法、局部施撤和挂袋法。一般采用局部施放为好,施放可在靠塘边约10～20米处。据使用者推荐,每公斤“鱼浮灵”施放在50米~2左右的面积较合适。施放时间最好在晚上11～12点左右。当 By the Chinese Academy of Sciences Institute of Hydrobiology and Wuhan pesticide plant joint screening, the development of the fish pond chemical oxygenator - “Yungunling” is a good PanTang emergency medicine, it is not only fast, but also easy to use and transport . At present, “fish floating spirit” quick-acting and long-acting two types of formulations. Quick-acting oxygen release faster, 4 to 6 hours in the water up to the highest oxygen value for first aid, long-acting type larger particle size, slow release of oxygen, suitable to prevent and improve water quality. “Floating spirit” in fish ponds used in the safe concentration of 50 mg / l, after use will not affect the quality of the fish, there is no residue. There are times the use of method, the Department of withdrawal and bagging method. Generally use the local cast as well, cast in the pond by about 10 to 20 meters. According to user recommendations, per kilogram of “fish floating spirit” in the area of ​​about 50 meters ~ 2 more appropriate. Casting time is best at about 11 to 12 o’clock in the evening. when
