摘　　要：探讨硫化氢对斑节对虾溞状幼体、糠虾幼体和仔虾的毒性,求出其安全浓度,为加强育苗期间的水质管理,促进育苗生产稳定健康发展提供科学的参考。用常规生物毒性试验方法研究硫化氢对斑节对虾溞状幼体、糠虾幼体和仔虾的毒性,计算斑节对虾各时期的半致死浓度(LC50)和安全浓度(SC)。在斑节对虾溞状幼体时期,24、48、72、96 h的半致死浓度LC50分别为0.856、0.720、0.413、0.377 mg/L;在斑节对虾糠虾幼体时期,24、48、72、96 h的半致死浓度LC50分别为5.167、4.460、1.387、0.940 mg/L;在斑节对虾仔虾时期,24、48、72、96 h的半致死浓度LC50分别为20.625、17.813、12.056、10.762 mg/L。硫化氢对斑节对虾溞状幼体、糠虾幼体和仔虾的安全浓度(CS)分别为0.038、0.094、1.076 mg/L。硫化氢对斑节对虾溞状幼体、糠虾幼体和仔虾毒性作用显著,随着硫化氢浓度的增加,对斑节对虾各时期幼体表现出不同程度的毒性作用。The toxicity of hydrogen sulfide to zoea larvae,mysis larvae and postlarvae of Penaeus monodon was discussed to find out the safe concentration for strengthening water quality management during healthy development of nursery production.Conventional biotoxicity test was adopted to test the toxicity of hydrogen sulfide on zoea larvae,mysis larvae and postlarvae of P.monodon and calculate the LC50and SC for each period.The LC50at 24,48,72 and 96 h was 0.856,0.720,0.413 and 0.377 mg/L respectively during the zoea larvae of P.monodon;the LC50at 24,48,72 and 96 h was 5.167,4.460,1.387 and 0.940 mg/L respectively during the mysis larvae of P.monodon;and the LC50at 24,48,72 and 96 h was 20.625,17.813,12.056 and10.762 mg/L respectively during the period of P.monodon postlarvae.The safe concentration(CS)of hydrogen sulfide for the zoea larvae,mysis larvae and postlarvae of P.monodon was 0.038,0.094 and 1.076 mg/L respectively.Hydrogen sulfide showed different degrees of toxicity with increasing concentration to zoea larvae,mysis larvae and postlarvae of P.monodon.
