工厂化循环水养鱼池曝气释放器养殖效果的研究

Study on Culturing Effect with Aeration Release Devices in Industrialized Recycled Water Aquarium

采用自行研制的曝气释放器装置——工厂化养鱼池曝气释放器,在工厂化循环水养鱼车间的6个试验池进行了2种曝气释放器试验池排污量、溶氧分布检测以及罗非鱼养殖试验。结果表明:该增氧装置增氧显著、养殖效果良好,与无罩曝气释放器相比溶解氧高出2.46mg/L,养殖产量提高了34.21%,且能使水体产生轻微蜗流,有利于鱼池污物排放和鱼类的生长,适合于工厂化循环水养鱼池养殖生产。

Adopted the release of aeration device which was self invented.Emissions,the distribution of dissolved oxygen were tested as well as tilapia aquaculture in the six industrialized recycled water aquarium. The results showed that:the oxygen-increasing device increased oxygen significantly and the effect of culture was obvious. The amount of dissolved oxygen in cover-release aeration increased 2.84 mg/L,more than that in the no cover-release aeration,and the production of tilapia increased by 34.21 %. It also ...
