북태평양 어장에서 명태 어획을 위한 소형 중층트롤 설계 및 성능 분석

Abstract

Abstract In the North Pacific, trawl fishing is mainly carried out for pollack. Fishing gear of a size suitable for these trawler specifications is important in the operation of fishing gear. In addition, large-scale Russian shipping companies with capital power in the North Pacific are currently introducing large trawlers. The fishing gear used here is mainly from Europe and is very expensive. Therefore, it is necessary to design trawlers and fishing gear suitable for small shipping companies. The purpose of this study is to calculate the predictive towing forces by using the main specifications of small trawler and to present a midwater trawl design. For the price competitiveness of the completed fishing gear, it was designed using polypropylene ropes and polyethylene nets. In addition, we propose a trawl design method suitable for the specifications of a fishing boat and present the utility of a kite.
