    摘要:

    根据2010年7月至2011年6月对浙南沿岸张网渔获物采样调查资料,研究分析张网渔获物优势种类组成及季节分布。结果表明,在全年取样调查中,共鉴定游泳生物97种。优势种类为中国毛虾、日本毛虾、龙头鱼、细螯虾、带鱼,双斑〖HT5”,7〗虫〖KG-*3〗寻〖HT5”SS〗、刀鲚以及小公鱼属、虎鱼科、口虾蛄属、管鞭虾属、仿对虾属、鼓虾属等12个类群。毛虾全年均有出现,在一年中出现旺季有两个,一个是3月至5月,再一个是7月至8月,各月样品中毛虾重量占比分别为41.5%、33.1%、36.4%、43.1%与77.2%。龙头鱼出现旺季主要在9月至10月,各月样品中重量占比分别为25.5%与39.7%,平均体重分别为1.2 g与1.1 g。带鱼出现旺季在6月至9月,各月样品中重量占比分别为3.2%、3.6%、1.4%与2.6%,平均体重分别为1.1 g、2.2 g、1.8 g与3.9 g。口虾蛄出现旺季主要在9月至10月,各月样品中重量占比分别为10.5%与9.2%,平均体重分别为3.5 g与4.8 g。

    Abstract:

    According to the survey data of net catch in sampling along the southern coast of Zhejiang from July 2010 to June 2011, research and analysis on dominant species catch composition and seasonal distribution of swing net were conducted. The results show that, 97 kinds of swimming organisms were identified in the annual sample survey. Dominant species were Acetes Chinensis, Acetes Japanese, Bombay duck, Leptochela gracilis Stimpson, Coiliaspp, Charybdis bimaculata, Coilia nasua, and genera of Anchoviella commersonii, Gobiidae, genera of edible mantis shrimp, genera of Solenocera Melantho, Parapenaeopsis, Alpheus were in the 12 groups. Acetes were encountered throughout the year, there are two busy seasons, one is from March to May, the other is in July and August, the monthly gross Acetes weight proportion of the sample were 41.5%, 33.1%, 36.4%, 43.1% and 77.2%. Bombay duck appeared mainly in September to October, accounting of the weight of the sample in each month were 25.5% and 39.7%, average weight were 1.2 g and 1.1 g. Coiliaspp occurred mainly in June to September, accounting for 3.2%, 3.6%, 1.4% and 2.6% of the weight of the sample each month, average weight were 1.1 g, 2.2 g, 1.8 g and 3.9 g. Edible mantis shrimp appeared mainly in the busy season from September to October, accounting for 10.5% and 9.2% of the weight of the sample in each month, average weight were 3.5 g and 4.8 g.
