池塘高密度养鱼,由于鱼类的呼吸、代谢物的分解和有机物的矿化而大量消耗水中的溶解氧,单靠浮游植物光合作用产氧远远满足不了鱼类需要,所以,鱼塘常出现浮头现象,影响家鱼产量.为此,必须采取增氧措施.增氧机是家鱼养殖中常用的增氧机械. Pond high-density fish, due to the respiration of fish, the decomposition of metabolites and the mineralization of organic matter and consume a large amount of dissolved oxygen in water, photosynthesis alone phytoplankton far can not meet the needs of fish, so often Floating phenomenon occurs, affecting the production of fish. To do this, we must take aerobic measures. Aerobics are commonly used in fish farming oxygen machinery.
