摘　　要：根据2010年4-9月对韭山列岛海洋生态自然保护区海域的渔业资源状况调查及分析资料,对该保护区的渔业资源状况进行了分析。结果表明:春、夏季调查海域共采集水生生物93种,隶属于5门、8纲、24目、55科,其中鱼类种类最多共有34种;春季共采集水生生物71种,隶属于5门、8纲、23目、47科,其中鱼类种类最多共有29种;夏季共采集水生生物66种,隶属于5门、7纲、18目、39科,其中虾蟹类种类最多共有26种。拖网渔获水生动物的优势种:春季优势种为中华栉孔鰕虎鱼、日本鼓虾、葛氏长臂虾、口虾蛄、龙头鱼和日本蟳;夏季优势种为龙头鱼、棘头梅童鱼、口虾蛄、中华管鞭虾和小黄鱼。扫海面积法估算调查海域的渔获水生生物的资源量,春季资源量最为丰富的为小黄鱼,资源量达到89.62(t6 866.35×104ind);夏季资源量最为丰富的是棘头梅童鱼,资源量高达1 996.59(t19 510.32×104ind)。Based on the data from the fishery resource monitoring in the sea area of Jiushan Archipelago Oceanic Ecology Reserve from April to September in 2010, the condition of the fishery resources was analyzed. The result showed that 93 species of aquatic animals were caught in the sea area during spring and summer, which belonged to 55 families, 24 orders, 8 classes and 5 phyla, the species of fishes was the most abundant accounting for 34 species; 71 species of aquatic animals were caught in spring, which belonged to 47 families,23 orders, 8 classes and 5 phyla, the species of fishes was the most abundant accounting for 29 species; 66 species of aquatic animals were caught in summer, which belonged to 39 families, 18 orders, 7 classes and 5 phyla, the species of crustaceans was the most abundant accounting for 26 species. The dominant species were Ctenotrypauchen chinensis, Alpheus japonicus, Palaemon gravieri, Oratosquilla oratoria, Harpadon nehereus and Charybdis japonica in spring; and H. nehereus, Collichthys lucidus, 0. oratoria, Solenocera crassicornis and Larimichthys polyactis in summer. In the fishery resources estimated by sweeping area method, the resource of L. polyactis was the most abundant for 89.62 t（6 866.35x104 ind） in Spring, and C. lucidus was the most abundant for 1 996.59 t （19 510.32x104 ind） in Summer.
