Abstract
The aims of this study are to estimate and assign the weight of each evaluation factor using the AHP technique which considers not only the technical·socio-economic factors, but also the resource status of the fish stock in order to derive the optimal vessel reduction scales. In order to set the optimal level in Korea, a questionnaire survey was conducted by public officials, professors, researchers, and industry workers. According to the results of the questionnaire, the weight of evaluation factor to be set in the vessel reduction was given. In addition, we compared and analyzed the effect of weight difference of important factors by group. As a result, public officials, professors, and researchers took a high weight of biological factors, otherwise industry workers took a high weight of socio-economic factors. Also, the optimal vessel reduction scales reflecting only the fishing effort level based on the resource assessment were 3,874 vessels in coastal fishery, and 222 vessels in offshore fishery. On the other hand, the optimal vessel reduction scales considering the technical factors and socio-economic factors were 3,513 vessels in coastal fishery, and 203 vessels in offshore fishery. In the analysis by group, the optimal vessel reduction scales of industry workers were relatively lower than those of public officials, researchers and professors.
