摘　　要：本文研究了鲈鱼受精卵及仔鱼对纳米催化电解技术消毒处理海水中游离氯的适应性,结果表明随着电解处理当量的升高,水体中含氯量的提高,鲈鱼受精卵的孵化率有所降低;当电解处理当量控制在4.9 w·h/t以内时,海水与经爆气中和的无残余氯海水的孵化率相近;经过9.6 w·h/t电解当量处理,海水中的余氯含量约为1.3 mg/L,该浓度对鲈仔鱼成活率影响较大;在经硫代硫酸钠中和、排除电解余氯的海水中,鲈鱼苗可进行正常培育,育苗效果有显著提高。This paper studied on the adaptability of perch seedlings to chlorine in the sea water from the nano catalytic electrolysis disinfection treatment. The results showed that with the increase of the equivalent of the electrolytic treatment and the amount of the chlorine in the water,the hatching rate of the perch fertilized egg decreased. When the electrochemical equivalent was controlled within 4. 9 w·h / t,the hatch rate of the sea water and that of non- residual chlorine of gas explosion sea water were similar. In the situation that electrolytic equivalent was 9. 6 w ·h / t,the residual chlorine content of treatment seawater was about 1. 3 mg / L,which had a greater impact on the survival rate of the perch larvae. After mixed by the thiosulfat and removing the electrolysis residual chlorine in seawater,the growing seedlings effect was improved for the normal breeding of perch.
