시장환경 변화에 따른 기선권현망어업의 경제적 영향분석

Abstract

The purpose of this study is to analyze an economic effect of the Korean anchovy boat seine fishery, dealing with changes in new market environment by focusing on a duty-free oil. This study utilizes the Clarke-Yoshimoto-Pooley (CYP) model which is an exponential surplus production model based on Gompertz growth function. The maximum sustainable yield (MSY) and fishing efforts (FMSY) in the level of the MSY are estimated by the CYP model. The bioeconomic model with market parameters, such as price and unit cost is based on CYP model and the bioeconomic model can estimate not only the maximum economic yield (MEY) and open access yield but also the fishing efforts in the level of the MEY and the open access yield. In addition, this study produces changes in producer surplus of the anchovy boat seine fisheries under open access and sole owner according to the duty-free oil support reduction. As results of the study, if the duty-free oil support is prohibited, the oil price which fishermen have to pay will increase and then the producer surplus of the anchovy boat seine fisheries will decrease. Increasing the oil price makes fishermen who are not able to manage their business resign themselves from their fishing ground. However, when fishing efforts of the anchovy boat seine fisheries are reduced less than FMSY, this study shows that the stock of the anchovy will increase.
