对虾工厂化养殖和土池养殖溶解氧消耗研究

Study on dissolved oxygen consumption both in industrial and pond cultures of shrimps

对工厂化养殖凡纳滨对虾和土池养殖中国对虾过程中的各耗氧因子进行了研究。结果表明,在中国对虾的土池养殖环境中,对虾耗氧量、水柱和底质耗氧量分别占总耗氧量的3.74%、17.35%和78.91%;在凡纳滨对虾的工厂化养殖环境中,对虾耗氧量占总耗氧的72.67%,水柱耗氧占27.33%。在对虾的工厂化养殖中,对虾耗氧是最大的耗氧因子;而土池养殖后期,底质耗氧是主要耗氧因子。

This paper studied the factors of oxygen consumption both in industrial Litopenaeus vannamei culture and soiled pond Fenneropenaeus chinensis culture. The result showed that the rates of oxygen consumption of F. chinensis, water column and sediment were 3.74 %, 17.35% and 78.91% respectively in soiled pond shrimp culture, and those of Litopenaeus vannamei and water column were 72.67% and 27.33% respectively in industrial culture. The shrimps＂ consumption of oxygen was the most important factor at the final culture period in industrial culture, however, the oxygen consumption of sediment was the most significant factor at the final culture in soiled pond culture.
