韩国政府正在制定一项管理渔捞努力量的计划，为恢复渔业资源规定每种渔业的最高渔具使用量。这将有助于解决渔业部门之间关于渔具的争端，稳定渔业经营条件。特别是在确定最大渔具使用量时，经济标准和生物标准被视为促进渔业可持续和经济上可行发展的重要因素。因此，这项研究是分析最佳经济渔具使用（EMEY）作为最经济有效的使用常见的章鱼陷阱渔业，最有争议的部门之一，在建立最大渔具使用。每次航行日志中的数据用于估计每次航行的EMEY，因为认为可用于分析的数据有限。分析结果显示，普通八达通捕集器船只每次行程的应急最低运作费用须减少约13%。也就是说，将钓钩使用量减少到EMEY的水平可以降低钓钩捕捞成本，从而增加钓钩利润。
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.
