| 摘 要： | 本研究采用静水实验法,在水温21℃、盐度30、pH8.10条件下,分析了水体氨氮对海月水母(Aurelia coerulea)螅状体以及碟状体的急性毒性作用,并且探讨了慢性氨氮胁迫对海月水母螅状体无性生殖的影响。急性毒性实验结果显示,氨氮毒性效应与浓度和胁迫时间呈正相关,氨氮对螅状体24、48、72、96h半致死浓度分别为225.60、164.26、62.67和25.44mg/L,氨氮对碟状体24、48、72、96h半致死浓度分别为49.96、31.53、24.54和21.43mg/L,螅状体与碟状体的总氨氮安全浓度分别为2.54和2.14mg/L,非离子氨安全浓度分别为0.13和0.11mg/L。慢性氨氮毒性实验显示,实验组螅状体产生的子代螅状体数少于对照组,而随着胁迫时间延长,螅状体繁殖子体的速率恢复至对照组水平。研究结果表明,氨氮对海月水母具有毒性作用,富营养化水体中氨氮含量升高不是海月水母暴发的直接原因;此外,海月水母螅状体可能具有一定的适应慢性氨氮胁迫的自我调节能力。
