摘要:: 2006—2007年夏季（2006年8月）、冬季（2007年1月）、春季（2007年4月）和秋季（2007年10月）在厦门海域利用底拖网渔船开展渔业资源调查.根据调查资料，对厦门海域（约2 713 km2）的渔业资源现状进行了评析.研究结果表明，4个季节渔业资源平均密度为981.97 kg/km2，其中秋季居首位，约为1 261.39 kg/km2；冬季和夏季次之，分别为951.31 kg/km2和936.93 kg/km2；而春季资源密度最低，约为778.24 kg/km2.各个季节的资源密度，鱼类均居首位，甲壳类次之，头足类最低.各季节鱼类优势种分别为：春季鱼类优势种有6种，以二长棘鲷（Parargyrops edita）幼鱼和短吻鲾（Leiognathus brevirostris）分别为第一和第二优势种；夏季有7种，以中华海鲶（Arius sinensis）和叫姑鱼（Johnius belengerii）分别为第一和第二优势种；秋季也有7种，以龙头鱼（Harpadon nehereus）、叫姑鱼和中华海鲶为主要优势种；冬季有4种，以叫姑鱼为最主要优势种.4个季节的平均渔业资源现存量约为1 694.71 t；渔业潜在可捕量约10 523 t.渔业资源分布与水温、水深及盐度关系较密切.该海域渔业资源已经明显衰退，急需加强渔业资源的管理和保护.

Abstract:: Based on the survey data collected by bottom trawl research in August 2006，January 2007，April 2007 and October 2007 in Xiamen coastal waters about 2 713 km2,the sweep area method was used to assess the average fisheries resources density and the fisheries resources.The results showed that the highest density was in autumn,around 1 261.39 kg/km2,winter and summer were next,around 951.31 kg/km2 and 936.93 kg/km2 respectively,and spring was the least，of 778.24 kg/km2.In this four seasons,the density of current fish resources was the highest,crustacean the next,while cephalopod the least.The dominant fishes in spring had six species,such as Parargyrops edita and Leiognathus brevirostris,etc.;seven species in summer,such as Arius sinensis and Johnius belengerii,etc.;also seven species in autumn,such as Harpadon nehereus,Johnius belengerii and Arius sinensis,etc.;and four species in winter,such as Johnius belengerii,etc.The current fisheries resources in Xiamen coastal was about 1 694.71 t,while the sustainable yield was up to 10 523 t by nutrient dynamic model.The distribution of fisheries resources had an obvious relationship with salinity,water temperature and depth.Furthermore,the fisheries resources were dramatically declining and urgent protection measures should be taken immediately.
