초록

본 연구에서는 붉은대게 어업관리 정책의 효과를 비교 분석하기 위해 국제적으로 널리 활용되는 생물경제 모델을 활용하였다. 구체적인 효과 분석으로는 TAC 정책과 어획노력량 절감 정책에 대한 분석을 위해 생물학적 효과와 경제적 효과를 구분하여 분석하였다. TAC 정책의 생물학적 효과 분석 결과 TAC가 현재 26,000톤 수준으로 설정되어 유지되면 10년 후 붉은대게 자원량이 106,000톤에서 73,076톤으로 감소할 것으로 추정됐다. 하지만 TAC 수준을 22,000톤으로 설정하면 향후 자원량은 125,316톤으로 증가하는 것으로 추정됐다. 어업노력량 감소의 경우 현재보다 30% 감소하면 자원량이 크게 증가하고, NPV도 가장 높은 수준으로 추정됐다.

In this study, internationally widely utilized bioeconomic models were used to make a comparison and analyze the effectiveness of red snow crab fisheries management measures. As a specific effect analysis, biological and economic effects of both total allowable catch (TAC) and effort reduction management measures were analyzed simultaneously. Model results showed that the red snow crab biomass would be decreased from 106,000 tons to 73,076 tons after ten years when the TAC is set to and maintained at the current level of 26,000 tons. The amount of biomass would be increased to 125,316 tons when the level of TAC is set to 22,000 tons. In cases of reduced fishing efforts, a 30% decrease from the current level would result in greater biomass and NPV would be also estimated at the highest level. In addition, a sensitivity analysis by market price was conducted to analyze the minimum TAC level of the red snow crab offshore pot fishery. Results showed that the minimum TAC level would be 8,210 tons when the market price increased by 30% and it would be also 15,247 tons when the market price decreased by 30%. Furthermore, results of the sensitivity analysis by fishing cost showed that the minimum TAC level was analyzed to be 13,857 tons when the fishing cost increased by 30% from the current level.
