Seahorses (genus Hippocampus) are flagship species for marine conservation and evolutionary studies.Wild seahorse populations have declined sharply because of overfishing or other disrupting activitie
分于2014年10月、2015年6月在南海北部陆架陆坡区研究了冬季和夏季浮游纤毛虫丰度和生物量的垂直分布.冬季纤毛虫丰度变化范围为0-1353ind/L,生物量变化范围分为0-2.36 μg C/L；夏季纤毛虫丰度变化范围为0-809 ind/L,生物量变化范围分为0-1.37 μg C/L.共鉴定出砂壳纤毛虫33属82种,其中冬季砂壳纤毛虫为39属64种,优势种为福雷号角虫、开孔真铃虫、酒杯类管
Three new and two known species of free-living marine nematodes of the family Ironidae from the East China Sea are described and illustrated.Conilia sinensis sp.nov.is identified by the relatively lar
鱼类群体的有效识别是了解鱼类种群结构和渔业可持续管理的重要途径,而耳石微量元素所包含的特征信息使其成为鱼类群体判别的重要方法之一.本文运用电感耦合等离子质谱仪测定了中国南海北部近岸海域(湛江、阳江、汕头)野生与网箱养殖群体的黄鳍鲷耳石微化学组成,分别运用5折交叉验证(5-fold cross validation)比较分析了线性判别分析(Linear Discrimination Analysis
The spotted sea bass Lateolabrax maculatus (Perciformes, Moronidae), is one of the most important commercial fisheries in west Pacific region, and has become a popularly cultured marine fish in China.
为了解热带中西太平洋延绳钓大眼金枪鱼(Thunnus obesus)适宜的温跃层参数分布区间,采用Argo浮标温度信息和中西太平洋渔业委员会(The Western and Central Pacific Fisheries Commission WCPFC)的大眼金枪鱼延绳钓渔获数据,绘制了热带中西太平洋月平均温跃层特征参数和月平均CPUE的空间叠加图,用于分析热带中西太平洋大眼金枪鱼中心渔场时
In the present papers, a total of 633 specimens of Engraulis japonicus were sampled from seasonal surveys in the East China Sea and Yellow Sea from May 2008 to February 2009.The diet composition and t
