摘要：

根据2006年夏季(8月)和冬季(1月)、2007年春季(4月)和秋季(10月)在闽江口及其附近海域利用底拖网作业的渔业资源调查资料, 应用传统扫海面积法以及Δ-分布模型法分析了福建闽江口及其附近海域(25°42′— 26°27′N, 119°42′—120°15′E)的渔业资源现存量。研究结果表明, 闽江口及其附近海域的鱼类、甲壳类的资源密度较高, 而头足类资源密度较低。渔业资源密度秋季居首位, 约为2569.11kg•km?2, 夏季次之, 约为1120.23kg•km?2, 而冬、春季资源密度较低, 分别为867.16和553.60.29kg•km?2。年平均渔业资源现存量约为4599t, 渔业潜在资源量达32451t。渔业资源分布与水温、水深关系较密切。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 the Minjiang River Estuary and its neighboring waters(25°42′-26°27′N, 119°42′-120°15′E), the sweep-area method and design-based method were used for assessing the mean fisheries resource density, fisheries resources and the 95% Confi-dence Interval (CI). The results showed that the current resources of fish and crustacean were relatively high, while cephalo-pod was low. The highest quantity density was in autumn, around 2569.11kg•km?2, followed by that in summer, around 1120.23kg•km?2; the density in winter and spring was less, of 867.16 and 553.60.29kg•km?2, respectively. The current fisheries resources in the Minjiang River Estuary and its neighboring waters are about 4599 t, while the potential fisheries resources is up to 32451 t. The distribution of fisheries resources has obviously relationship with water temperature and depth. Furthermore, the fisheries resources were in a low level, and urgent protection measures should be taken immediately.
