생물경제모형을 이용한 참조기의 자원평가에 관한 연구

Abstract

This study analyzes a stock assesment of yellow croaker caught mainly by the Korean stow net and gill net fisheries focused on single species and multiple fisheries. This study standardizes fishing efforts for the two fisheries using the general linear model and uses a surplus production model based on the exponential growth model. The Clarke·Yoshimoto·Pooley model estimates a maximum sustainable yield(MSY), an allowable biological catch(ABC), fishing efforts for MSY and for ABC. The bioeconomic model is used to estimate a maximum economic yield(MEY) and fishing efforts for MEY. Also, the study uses economic analysis to estimate economic interaction between stow net and gill net fisheries. The economic analysis shows the net profit of the two fisheries from estimated ABC. Finally, the study compares TACs based on single species and single fishery to TAC based on single species and multiple fisheries. The study suggests the necessity of TAC assessment for the single species and multiple fisheries for preservation of resources.
