摘  要：
依据单拖网渔船2010年在舟山渔场进行捕捞作业时渔捞日志所记录的统计数据,开展了总渔获量以及渔获优势种时空分布的研究。结果显示,总渔获量在1～2月产量下降,3～5月产量在持续上升。禁渔期过后,9月产量显著上升,随后10～12月产量先上升后下降。总渔获量空间分布为,春季在30°18′～31°00′N,124°18′～25°18′E范围内渔获量相对较高;秋季渔获量最高分布在30°18′～31°00′N,123°00′～123°18′E之间;冬季在29°00′～30°00′N,125°00′～125°18′E范围内渔获量相对较高。秋季渔获量较春季和冬季明显增加。渔获量随时间变化的趋势大于随空间变动的趋势。渔获物中优势种类包括日本红娘鱼Lepidotrigla japonice、带鱼Trichiurus haumela、小黄鱼Pseudosciaena polyactis,渔获比例分别达到16.88%、7.58%、4.58%。研究结果表明,季节是影响优势种产量的主要因素。带鱼的高产季节为春季,小黄鱼高产则主要出现在春季和秋季,红娘鱼主要集中在春季和冬季。从各优势种产量的空间分布看,舟山渔场单拖网作业带鱼高产区主要分布在29°05′～31°18′N、123°00′～125°13′E范围内;小黄鱼产量主要分布在29°00′～30°34′N、122°34′～125°34′E范围内;红娘鱼产量主要集中在29°00′～31°10′N、123°00′～125°09′E区域内。

摘  要：
Based on the statistical data recorded in the logbooks of five single trawler vessels that fishing in Zhoushan fishing ground in 2010,the spatial and temporal distribution of total catch and catches of dominant species were analyzed.The results showed that the total catch decreased in January and February,but increased from March to May.After the closed fishing season,the total catch significant increased in September.From October to December,the total catch increased firstly and then decreased.The spatial distribution characteristics were as follow: the high catch appeared within 30°18′-31°00′ N,124°18′-25°18′ E in spring.In autumn,the high catch appeared within 30°18′-31°00′ N,123°00′-123°18′ E.In winter,the high catch appeared within 29°00′-30°00′N,125°00′-125°18′E.Catch in winter was higher than those in spring and au-tumn.The temporal factors had more impact on catch than spatial factors.The dominant species including Lep-idotrigla japonica,Trichiurus haumela and Pseudosciaena polyactis,whose catch percentages were 16.88%、7.58%,4.58%.The research results indicated that season is the main factor affecting the catches of dominantspecies,the high catch season of T.haumela was spring,the high catch seasons of P.polyactis were spring andautumn,and the high catches of L.japonica were spring and winter.In view of the spatial distributions of dom-inant species,the high catch of T.haumela mainly appeared in 29°05′-31°18′N,123°00′-125°13′E,whilethose of P.polyactis,and L.japonica were mainly came from 29°00′-30°34′N,122°34′-125°34′E and 29°00′-31°10′N,123°00′-125°09′E.
