摘 要:为了解舟山市小干岛附近海域渔业资源状况,并为其可持续开发利用提供科学依据,文章于2016年5月(春季)在该海域设置15个站位,进行渔业资源定点拖网调查;采用相对重要性指数以及Shannon-Weaver指数、均匀度指数和丰富度指数,分析该海域的生物种类和生物多样性。研究结果表明:研究区生物种类有47种,为12目31科40属,优势种包括六丝钝尾虾虎鱼等3种,常见种包括日本鼓虾等9种;鱼类在质量和尾数方面都占绝对优势,虾类和蟹类也较多,渔业资源个体较小、经济价值较低;各调查站位的生物量和尾数分布有所不同;与其他海域渔业资源相比,研究区的生物多样性处于中等水平,应加强保护和恢复。In order to realize the present situation of fishery resources in the sea area near Xiaogan sland, Zhoushan, and provide scientific basis for sustainable fishery resources utilization, an inves tigation was carried out on the bottom trawl fishery resources of 15 stations in May 2016.The rel ative importance index, Shannon Weaver index, evenness index and richness index were used to analyze the composition and diversit species were identified, belonging to y 1 of fishery resources. The study showed that a total of 47 2 orders, 31 families and 40 genera. The dominant species were Arrlblychaeturichthys heg'anerrla, Decapterus Decapterus and Leptochela gracilis, there were 9 common species, such as Alpheus japonicus etc. The weight and number were dominated by fishes, shrimps and crabs were the second. The fishery resources were low value and cheapCompared with other sea areas, the diversity index was medium level, which means that the fishery resources should be protected and restored.
