A Bioeconomic Analysis of the Sandfish (Arctoscopus japonicus) Management Policies of the Eastern Sea Danish Fishery in Korea

Before implementing resource management measures, it is essential to establish the goals of fisheries by assessing current biomass status and level fishing effort. This study aims compare surplus production models, i.e., process-error state-space based on how they fit observed data. The effects Sandfish Stock Rebuilding Plan are analyzed using a bioeconomic model. analytical results show that least error between estimated catch per unit effort Therefore, analysis obtained model considered as most reliable. total allowable for Korean sandfish set at 2196 tons year. However, if we increase regulation standard available annual 50%, could be depleted. Furthermore, NPV decreased 172,599 thousand won after ten years, in 2029. recommendation this when policies stock prioritize recovery, would facilitate rebuilding.
