  ABSTRACT: It is important to estimate the productive efficiencies of industries, especially the fishing industry, in order to determine policies that can improve business conditions. In this study, the productive efficiency of the sandfish coastal gillnet fishery on the east coast of Korea has been estimated using stochastic frontier analysis (SFA). A translog production function wherein the inefficiency was represented by a truncated-normal distribution was established; the output variable was the trip production quantity, the input variables were physical production factors directly related to the fishing activities of vessels, such as tonnage, horsepower, and the number of employed fishers. The average productive efficiency of the sample was 0.59 [0.40–0.79], which implied that productive inefficiency occurs in sandfish coastal gillnet vessels. Moreover, it was verified that there are no differences among the average productive efficiencies of fishing vessels of different tonnages.

  ABSTRACT: The Korean Government is in the process of establishing a plan for managing fishing effort by setting up the maximum fishing gear usage per fishery type for the recovery of fishery resources. This will aid settlement of disputes between fishery sectors over fishing gears, and the stability of fishing business conditions. Especially in the setting up of the maximum fishing gear usage, economic standards as well as biological standards are being considered as significant factors to promote the sustainable and economically viable development of fisheries. This study is, thus, to analyze the optimal economic fishing gear usage (EMEY) as the most economically efficient usage for the common octopus trap fishery, one of the most controversial sectors in establishing maximum fishing gear usage. Data from logbooks per trip were used for estimation of EMEY per trip because it was considered there were limitations of data available for analyses. As a finding drawn from the analyses, the EMEY of common octopus trap vessels per trip has to be decreased by approximately 13%. That is, reducing the trip trap usage up to the level of EMEY can lead to the reduction of trip fishing costs, thereby resulting in increased trip profits.
