| 内容記述 | The research and development of selective fishing gear for coastal trawls has been carried out in many research institutes. However, there is very little literature describing the design concept of the fishing gear. The Choshi design of coastal selective trawl net, developed with fisherman, is used as a selectivity reference tool and technical data describing its performance are discussed. Development of a selective trawl net for the Choshi coastal fishery started in 1994. The Choshi coastal selective trawl net has a vertically separated cod end system with desired selection characteristics being achieved after investigating a range of separation constructions and associated net structures. In 1998 all coastal trawlers in Choshi region adopted the use of the CD-STN. The development process in the CD-STN was divided into three stages; primary, secondary and tertiary. In the primary stage, the separation panel was installed in the trawl cod-end. However, the selective function of panel was inhibited by many kinds of marine fauna and debris. In the secondary stage of development, fish and shellfish were successfully guided into the upper cod-end without the use of a separation panel, and marine fauna and debris into the lower cod-end successfully using a function of net structure. The tertiary development stage was a modification of the secondary stage with a large mesh window panel in top cod-end for releasing the juvenile fish. The Choshi-type coastal selective trawl net CD-STN is characterized by not having a separation panel in the trawl cod-end and it's selectivity function is related to the net structure design and the fish swimming performance. | |||||
