本文根据2003～2004年台湾海峡渔业资源调查资料,结合以往闽南、台湾浅滩渔场鲐鲹鱼类监测资料,研究分析了台湾海峡鲐鱼捕捞群体结构及资源开发利用状况。结果表明:台湾海峡鲐鱼资源主要为灯光围网作业和拖网作业所利用;5、6月在灯光围网作业主要渔获物中鲐鱼占绝对优势,其余各月所占比重均较低,其渔获群体优势叉长组为230～260mm,占60.8%,平均叉长246.1mm,资源利用较合理;而拖网作业捕捞群体以0龄鱼和1龄鱼为主。定点调查表明5月鲐鱼数量分布的主要密集区出现在闽南、台湾浅滩渔场的近岸海域,以幼鱼为主,8月群体较为分散,密集度不高。为合理利用鲐鱼资源,应加强对灯光围网作业扶持力度。
Based on the survey data of Taiwan Strait Fishery Resources from 2003 to 2004 and the previous monitoring data of catfish in Minnan and Taiwan Formations, the fishing population structure and resources exploitation and utilization in the Taiwan Strait were studied. The results showed that the resources of the anchovy in the Taiwan Strait were mainly used by the operation of the light fencing and the trawling operations. In June and June, the catfish accounted for the absolute predominance of the main catch in the light fencing operation, while the rest accounted for a relatively low proportion in each of the catchments. The advantage of grouping was 230-260mm, accounting for 60.8%. The average length of fork was 246.1mm, and the utilization of resources was more reasonable. However, the trawling fishing groups were dominated by 0-year-old fish and 1-year-old fish. The site-specific survey showed that the major dense areas of the distribution of bonito in May occurred in the coastal waters of Minnan and Taiwan Shallow Bank fisheries, with the juveniles as the main areas. In August, the populations were relatively scattered and the concentrations were not high. In order to make rational use of anchovy resources, efforts should be made to support the operation of the light fence.
