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.
