摘　　要：以国家973项目研究调查所获得的资料数据为基础,分析了黄海南部水域渔业海洋学特征、银鲳洄游行为及与渔场形成、渔期更迭关系。着重分析了2006年与2007年春季水温变化对渔场、渔期分布的影响。结果显示,水温的空间分布是春季南黄海银鲳鱼群分布与渔场形成的重要因子,相对于2006年春,2007年黄海南部水域升温较快,鱼群进入渔场的时间较2006年更早;2007年渔汛盛期从5月上旬开始一直持续到5月中旬结束,比2006年鱼群更为密集,规模更大,12℃是春季渔汛盛期开始的重要环境因子;同时,文中分析了南黄海大沙和吕泗渔场的性质特征,以为银鲳渔情预报提供基础资料。Based on the data from the National Basic Research Program of China(973 Program),'The response of biodiversity and fishing ground dynamics to the marine physical environmental evolution in typical waters',we investigated fisheries characteristics of the Yellow Sea waters,the migratory behavior of P.argenteus and the distribution of fishing grounds.The influence of SST on the distribution of fishing ground and season of P.argenteus were analyzed in spring 2006～2007,and the results showed that,the SST had a great impact on the distribution of P.argenteus and commencement of fishing season in the South Yellow Sea in early spring.The water temperature rose more rapidly in 2007 than 2006,leading to an earlier ingress of dense fish groups.The high fishing season occurred from May 5 to about May 20,with a larger concentration and a greater scope in 2007 than 2006 in spring.The SST was 12 ℃ at the beginning of the high fishing season.Meanwhile,the characteristics of two important fishing grounds: Dasha and Lüsi fishing grounds in the Southern Yellow Sea,were discussed in order to provide basic data for fishing forecasting.
