海蜇(Rhopilema esculenta Kishinouye)又名水母,属腔肠动物门(Coelenterata),钵水母纲(Scyphozoa),根口水母目(Rhizostomeae),根口水母科(Rhizostomatidae),海蜇属(Rhopile-ma)。海蜇型世代交替生殖,水母型通过有性生殖产生无性世代水螅型,水螅型通过横裂生殖产生有性世代水母型。水螅型营固着生活,水母型营浮游生活,通常所说的海蜇是指水母型成体。天津是海蜇的主要产地,但其资源量不稳定,有时大量出现,有时踪迹全无,自然采捕量已远远满足不了市场的需求。因此,进行海蛰的人工养殖已势在必行。根据海蛰的生态和生活习性,结合天津市大水面海水养殖特点,由天津市水产技术推广站承担的天津市水产局下达的“海蜇大水面围栏养殖技术研究与示范”项目,通过项目成功的实施,为天津地区养 The jellyfish (Rhopilema esculenta Kishinouye), also known as jellyfish, belongs to the genus Coelenterata, Scyphozoa, Rhizostomeae, Rhizostomatidae and Rhopile-ma. Jellyfish-type generation alternately reproductive, jellyfish through sexual reproduction produce asexual generation Shuina type, Shuina type reproductive generation through the genital generation sexual jellyfish type. Hydra type camp solidified life, jellyfish camp planktonic life, commonly referred to as jellyfish jellyfish adult. Tianjin is the main producing area of ​​jellyfish, but its resources are unstable, sometimes appear in large quantities, and sometimes there is no trace of it. Natural harvesting has far failed to meet the needs of the market. Therefore, the artificial breeding of jellyfish is imperative. According to the ecology and living habits of jellyfish and the characteristics of seawater aquaculture in Tianjin, the “Research and demonstration of jellyfish large surface pen culture technology” issued by Tianjin Fisheries Bureau, which is undertaken by Tianjin Aquatic Technology Extension Station, Successful implementation for the Tianjin area to raise
