摘要：试验旨在分析新型微米纯氧气泡增氧养殖大菱鲆的效果。试验采用微米纯氧气泡增氧和机械增氧2种方式，设置机械增氧组（溶解氧6~9 mg/L）、微米纯氧增氧Ⅰ组（溶解氧6~9 mg/L）和微米纯氧增氧Ⅱ组（溶解氧15~20 mg/L）3个试验组。结果表明，微米纯氧Ⅰ组大菱鲆的体重增长、成活率、肥满度及饵料转化率高于机械增氧组；微米纯氧Ⅱ组各指标低于机械增氧组。7个月的大规模生产试验（800 m2水面，溶解氧6~9 mg/L）表明，采用微米纯氧气泡增氧养殖大菱鲆，各测定指标均显著高于机械增氧，可以加快大菱鲆生长，提高成活率和饵料转化率。

Abstract: Effect of nano-metre pure oxygen in turbot (Scophthalmus maximus) farming was determined in this study. The facilities of air aeration and nano-metre pure oxygen (diameter of oxygen bubble was from 10 μm to 100 μm) were used. Three treatments, including air aeration (6~9 mg/L), pure oxygen I (6~9 mg/L) and pure oxygen II (15~20 mg/L), were designed. Growth rate, survival rate and feed translation rate (FCE) were measured. The results indicated that, when dissolved oxygen concentration varied from 6 mg/L to 9 mg/L, turbots in nano-metre pure oxygen system were higher on growth, survival rate and feed conversion efficiency (FCR) than those of air system; A farming trial was conducted to determine growth difference of turbot between pure oxygen and air system. Length growth, weight growth, survival rate and FCE were better in nano-metre pure oxygen system than air system. The results suggested that nano-metre pure oxygen was better than aeration in turbot farming system when dissolved oxygen concentration was from 6~9 mg/L.

Key words: nano-metre oxygen, aeration, dissolved oxygen, turbot, growth, survival rate, FCE
