新华社青岛７月２３日电（记者张旭东）中科院专家与国家海洋局北海监测中心科技人员密切合作，日前发现连续四年在河北秦皇岛沿海一带出现的“微微型藻赤潮”应更贴切地命名为“褐潮”，其原因种为抑食金球藻。

    The xinhua news agency Qingdao July 23 report（Reporter ZhangXuDong）The Chinese academy of sciences and the state oceanic administration expert north sea monitoring center of scientific and technical personnel close cooperation，For four years has discovered in hebei qinhuangdao appear along the coast“Slightly type of red tides algae”Should be more aptly named“Brown tide”，The reason for the suppression of any food gold。

    中科院海洋研究所研究员于仁成介绍，从２００９年开始在河北秦皇岛沿岸海域出现的“褐潮”，其影响范围已扩展至山东荣成一带海域。此前，人们一直以为这是一般的“赤潮”灾害。

    The Chinese academy of sciences researcher at the institute of Marine YuRen into paper，From 2009 to and the coastal area in hebei qinhuangdao appeared“Brown tide”，Its influence scope has been expanded to shandong glory become sea area。after，It was thought that this is normal“Red tides”disasters。

    ２００９年６月，河北秦皇岛沿岸海域出现一类新的有害藻华，致使海水呈黄褐色，前后持续约４０天。藻华区从山海关延伸至抚宁，扇贝、牡蛎和贻贝出现滞长现象，严重时有贝类死亡。类似的有害藻华在２０１０年至２０１２年连续来袭。

    June 2009，Hebei qinhuangdao in the coastal area of a new harmful algal blooms，The yellowish-brown sea water，For about 40 days before and after。HuaOu algae from shanhaiguan extends to FuNing，scallops、Oysters and mussels appear long lag phenomenon，Serious death has shellfish。Similar harmful algal blooms in 2010 to 2012 years continuous attacks。

    于仁成说，引发该藻华的原因种藻细胞只有２微米左右，属微微型藻类。这种藻的细胞脆弱，不易保存，可供分类学鉴定的形态特征不明显，加上国内相关研究人员对微微型级别藻类的研究经验不足，未能对该藻华原因种进行明确鉴定，只是将其归为“微微型藻藻华”或“微微型藻赤潮”。

    YuRen this，Cause the cause of the algal blooms of algal cell only 2 microns or so，Slightly type of algae。The algae cells vulnerable，Won't keep，The morphological characteristics for taxonomic evaluation is not clear，Plus domestic related researchers on the type of research level slightly algae to lack experience，For this reason not algal blooms a clearly identified，Just for the return“Slightly type algae algal blooms”or“Slightly type of red tides algae”。

    中科院海洋研究所科研人员在国家海洋局北海监测中心密切合作下，通过色素分析和分子生物学鉴定方法，最终将引发该有害藻华的原因种圈定为海金藻类中的抑食金球藻。

    Marine research institute of Chinese academy of sciences research staff in the state oceanic administration monitoring center under the north sea close cooperation，Through the pigment analysis and molecular biology identification method，Eventually will cause the harmful algal blooms cause of a sea of gold for delineating algae feed or any gold。

    于仁成介绍，抑食金球藻具有抑制贝类摄食的能力，中文名是根据它的拉丁名含义（抑制摄食的金色球形藻细胞）翻译而来。抑食金球藻细胞大小约２微米，是连续２０余年在美国东海岸暴发的褐潮的主要原因种。

    YuRen introduced into，Any food or gold can inhibit the ability of shellfish ingest，Everybody else is according to its Latin name meaning（Restrain the golden ball algae feed）Translation and to。Any food or gold cell size about 2 microns，For more than 20 years in the United States is on the east coast of the outbreak is the main reason for the kind of brown tide。

    “因此，将河北沿海连续四年暴发的这种有害藻华称为‘褐潮’更加确切，并有利于我国有害藻华的研究与管理以及与国外的交流。”中科院海洋研究所研究员周名江说。

    “so，Will hebei coastal for four consecutive years of this kind of harmful algal blooms outbreak is called‘Brown tide’More exact，Harmful algal blooms beneficial to China and the research and management and exchange in foreign countries。”The Chinese academy of sciences researcher at the institute of Marine MingJiang weeks said。

    据了解，从１９８５年起美国东海岸开始出现褐潮，之后受影响海域的海湾扇贝种群数急剧下降，纽约州的佩克尼克斯湾海湾扇贝资源几近崩溃。

    According to understand，Since 1985 the east coast of the us began to appear brown tide，After the gulf waters of the affected population size scallops fell sharply，The New York knicks bay scallops peck gulf resources to pieces。

    我国是继美国和南非之后第三个出现褐潮的国家，对我国来说这是一种新出现的海洋生态灾害，目前对其暴发机制、危害方式、生态效应等缺乏基本的科学认识，所以难以提出有效减轻灾害的措施。

    Our country is the United States and South Africa after the third appear brown of the tide in the country，For our country this is a kind of new Marine ecological disaster，At present the outbreak mechanism、Harm way、The ecological effects lack basic scientific knowledge，So hard to put forward effective measures to reduce the disasters。

    褐潮对养殖业的危害极大，研究难度也很高，专家建议应在国家层面设立“褐潮专项”，对抑食金球藻及其引发褐潮的机理、快速检测与识别方法等以及褐潮的新型监测与预警手段进行研究。

    Brown tide of aquaculture of great harm，The difficulty is also very high，Expert advice should set up at the national level“Brown tide special”，To eat or any gold and the resulting brown tide mechanism、Rapid detection and recognition method and the new brown tide monitoring and warning means for research。
