摘　　要：为了解海月水母在天津海域的分布特征,于2021年1—12月进行了海月水母蝶状体和成体的调查。结果表明:蝶状体自3月份开始在以中心渔港为主的天津市近岸有礁石和人工岸线海域出现,4月份数量达到最高。成体数量和伞径从5月份开始增加,到8月份达到峰值,随后下降,10月份天津近岸海域海月水母基本消失。蝶状体与海水温度和盐度显著相关,而成体与海水温度、叶绿素a极显著相关。综上,天津海域海月水母为本地型,其生长规律与渤海其他海域基本类似,为避免海月水母的影响,建议海蜇在5月初远离岸线海域进行增殖。To explore the distribution of Aurelia sp.in the coastal Waters of Tianjin,a survey of Aurelia sp.ephyrae form January to April in 2021 and Aurelia sp.adult form May to December in 2021 was conducted.The results showed that the ephyrae appeared in the coastal areas with reefs and artificial shoreline in Tianjin from March,which was dominated in the Central Fishing Port of Tianjin,and the number of ephyrae reached the highest in April.Both the abundance and the bell diameter of Aurelia sp.increased from May to August,then decreased,and the Aurelia sp.disappeared in October.The abundance of Aurelia sp.ephyrae was highly correlated to the temperature and salinity.And abundance of Aurelia sp.adult was highly correlated to the temperature and chlorophyaa-a.In conclusion,the Aurelia sp.in the coastal waters of Tianjin was considered to a native type due to the presence of ephyrae,and their growth patterns were basically consistent with those in other waters.In order to avoid the influence of Aurelia sp.,it is suggested that the larva of Rhopilema esculentum should be released away from coastal waters in early May.
