Abstract
This study is aimed to analyze the economic effectiveness of the Black Scraper (Thamnaconus modestus) fry releasing program in Busan, Republic of Korea. Since the 1990s, the catch of Black Scraper has decreased rapidly and has maintained a low level of catch to date. Currently, the fry releasing program is being implemented as one of the efforts to enhance the stock biomass. However, researches that analyze the economic effectiveness of program have been limited. Therefore, in this study, based on the results of fishing investigation and genetic analysis, we analyzed the economic effectiveness of Black Scraper fry releasing program using a benefit/cost ratio method. The period range of the analysis for the program was from 2020 to 2022. As a result of the analysis, we found that there was no economic feasibility of the program both in 2020 and 2021. But in 2022, the benefit/cost ratio was estimated to be 2.4, indicating that the program was evaluated to be economically feasible.
