山东缢蛏人工繁育试验及高盐对幼虫生长的影响崔玉龙1，姜珊1，吴彪2，曹伟2，3*，于贞贞4，陈聪聪4，赵磊4(1．荣成市海洋经济发展中心，山东荣成264300;2．中国水产科学研究院黄海水产研究所，山东青岛266071;3．浙江海洋大学国家海洋设施养殖工程技术研究中心，浙江舟山316022;4．东营市海洋发展研究院，山东东营257091)摘要研究了山东地区缢蛏人工繁育过程及盐度对幼虫生长的影响。结果发现，山东地区能够顺利培育缢蛏苗种，其受精卵在23℃条件下发育24h便可进入D形幼虫阶段，浮游期约为8d，每天生长约15μm，变态后生长速度稳步加快;将幼虫在14、21、28盐度梯度下培育发现，随着盐度的升高，其壳长生长速率显著下降(P＜0．05)。该研究结果可为山东地区开展缢蛏人工繁育提供参考。关键词缢蛏;人工繁育;盐度;幼虫;生长中图分类号S968．3文献标识码A文章编号0517－6611(2023)07－0085－03doi:10．3969/j．issn．0517－6611．2023．07．021开放科学(资源服务)标识码(OSID):ExperimentonArtificialPropagationandEffectofHighSalinityonLarvaeGrowthofSinonovaculaconstrictainShandongCUIYu-long1，JIANGShan1，WUBiao2etal(1．ＲongchengMarineEconomicDevelopmentCenter，Ｒongcheng，Shandong264300;2．YellowSeaFisheriesＲesearchInstitute，ChineseAcademyofFisherySciences，Qingdao，Shandong266071)KeywordsTheartificialbreedingprocessofrazorclamsinShandongandtheeffectsofsalinityonthegrowthoflarvaewerestudied．There-sultsshowedthatrazorclamcouldbesuccessfullypropagatedinShandong，andtheirfertilizedeggscouldentertheD－shapedlarvalstageafter24hofdevelopmentat23°C．Thelarvalstagewasabout8days，withagrowthrateofabout15μmperday，andthegrowthratesteadilyacceler-atedafterlarvalstage;thelarvaewerebredunderthreesalinityof14，21and28，anditwasfoundthattheshelllengthgrowthratedecreasedsignificantlywiththeincreaseofsalinity(P＜0．05)．TheresultsofthestudyprovideareferencefortheartificialpropagationofrazorclamsinShandong．KeywordsSinonovaculaconstricta;Artificialpropagation;Salinity;Larvae;Growth基金项目宁波市“科技创新2025”重大专项(2019B10005);宁波市重大科技攻关暨“揭榜挂帅”项目(2021Z114)。作者简介崔玉龙(1981—)，男，山东威海人，工程师，从事水产养殖研究。*通信作者，...
