在现代水产养殖系统中,鱼类的养殖密度指标不断增加,而为了节约水资源,其换水率却在不断下降,造成溶解于水中的二氧化碳含量增加二氧化碳对鱼是有害的,因为它降低了鱼体血液的输氧能力,严重时会造成窒息死亡。当养殖密度小于30~60kg/m3时,常规的鼓风曝气增氧通常可以通过气泡石 In modern aquaculture systems, the indicator of stocking density of fish is constantly increasing, and in order to conserve water resources, its water exchange rate is declining, resulting in an increase in the amount of carbon dioxide dissolved in water. Carbon dioxide is detrimental to fish as it reduces Oxygen supply to the body’s blood can cause asphyxiation and death in severe cases. When the culture density is less than 30 ~ 60kg / m3, the conventional aeration aeration can usually bubble stone
