To achieve sustainable fisheries management, it is of great importance to understand how a fish stock responds to the synergies of these factors. In this study, I propose to explore the stock status of cutlassfish Trichiurus lepturus, based on fisheries surveys in Taiwan (including bottom trawl, set net, and recreational fisheries). The over-reaching goals of this project are to understand long-term stock dynamics of hairtail and provide scientific information for management purposes. Specifically, I plan to conduct the following data collection and analyses: 1) historical catch and distributional data; 2) contemporary catch and effort and life history data. 3 -白帶魚生活史漁獲產量努力量cutlassfishCPUElife history
