시뮬레이션 방법을 통한 선망 어구의 침강속도 해석

Abstract

Korea is surrounded by sea on three sides of the sea. Therefore, marine products occupy a very important position in terms of food resources. In recent years, By the change in people"s eating habits values change and food preference increased the appetite preference of marine products. According to the Ministry of Oceans and Fisheries in Korea, The total production of Korean fishery is around 3.3 million M/T. Especially, purse seine fishery produced around 5.4 hundred thousand M/T. Thus, purse seine fishery shared around 14 percent of the total fishery"s production. So, a performance improvement of purse seine will increase the fishing efficiency. The purpose of this study evaluates the sinking performance of the present purse seine gear using a numerical method. Furthermore, this study will present an alternative for improving the sinking performance of the purse seine in terms of different type of materials, mesh sizes, buoyancy and sinking forces. This study will be helpful to improve the fishing efficiency in purse seine fishery.
