摘　　要：以大菱鲆(Scophthalmus maximus)幼鱼为实验对象。采用正交设计,设定不同浓度的溶解氧、氨氮和亚硝酸氮,研究在三者交互作用下大菱鲆幼鱼的摄食和生长情况,得到其数值模型。结果表明,提高溶解氧的浓度能显著降低氨氮和亚硝酸氮对大菱鲆幼鱼的毒性,改善其生长环境,提高大菱鲆幼鱼的摄食、生长和饵料利用水平。研究表明,在循环水养殖过程中,可以通过增加溶解氧的浓度来降低有毒物质对大菱鲆的毒性,以此减小生物处理的压力,从而减少生物过滤装置的成本投入,提高经济效益。Three factors （DO, un-ionized ammonia and nitrite） were designed for their effects on growth and feed intake of juvenile turbot with orthogonal array design. The feeding and growth numerical model was attained. The results indicated that it could significantly reduce the effect of un-ionized ammonia and nitrite on the growth, feed intake and feed conversion ratios of juvenile turbot. It was showed that impro- ving DO may not only reduce the toxicity of un-ionized ammonia and nitrite on the juvenile turbot and the pressure of the bio filter in the recirculating aquaculture system （RAS）, also improved the economic effi ciency.
