摘  要:
收集了1995年-1997年三年帆张网周年渔获物样品110批、分析样品重量595.141kg,生物学测定带鱼、小黄鱼、鲳鱼等主要经济鱼类共7387尾,统计了71航次、1654次有效网次总渔获全为575263.2kg的渔捞记录。对三年间监测船在29°30'-34'N、122°30'E以东海域所得渔获物组成和主要经济种类资源状况进行了综合分析,监测结果表明:三年间,帆张网渔业资源结构以1995年较好,1997年次之、1996年较差。主要经济种类一带鱼资源状况1995年较好,1996年处在低水平状态,1997年资源稍好转,幼带鱼生长较快,渔获群体组成明显大于1996年与1995年相近。

摘  要:

Statistics covered 1 654 times of valid net operation in 71 times of voyage; the re-lated weight was 575 263. 2 kg. Resource of main economic fishes and sail stow net situation in the areaeast to 29°30'N ~ 34°N' 120°30'E in recent consecutive years were studied.The statistics chowed thatthe resource situation in 1995 was better than in 1997, with in 1996 being worst. As to main economicfishes-hiartail, the situation in 1995 was better, and plunged into its lowest level in 1996. ln 1997,it took a tum for the better and smal hairtail grew faster, fish size was significantly greater than in 1996and almost reaches the level of 1995.
