近年來我國政府針對蟹類已採取相關保育措施,例如蟹類漁獲物體長管制已及漁季 限制等,但保育措施仍必須根據科學基礎進行滾動式調整。本研究目的在於評估蟹 類資源保育措施並從中尋求資源保育與漁民收益的平衡點。基於研究目的,本研究 蒐集樣本船資料及生物樣本資料加以分析。根據本研究結果發現,根據情境模擬分 析,較具經濟可行的保育管理措施包括,體長管制調整(自原有限制增加1公分)、產 卵月份漁獲努力量減少、產卵月份休漁已及產卵月份禁捕抱卵開花母蟹,長期目標 則是透過漁民組織進行自主性共同管理。因此,本研究結果將可提供漁政管理單位 及資源保育措施決策時之參考依據。

研究報告摘要(英)


This study tried to find out commercial crab resources management measures in the northern waters off Taiwan, in addition, to find a balance between resource conservation and fishermen’s revenues. In recent years, the Taiwan government agencies have taken several crab resource management measures, such as body size limitation and seasonal controls, but adoptive management should be taken for modifying the current management based on scientific evidence. To meet the research objectives, sample vessel data and crab biological samples were collected to be analyzed, and we conducted scenarios simulation to estimate the impacts of resources management scenarios on fishermen’s economic performances. Based on our findings, several crab resources management measure might be feasible, including body size control adaptation, input (fishing effort) control in the spawning season, and forbidden to catch obvious female crab n the spawning season. Eventually, the findings of this study could provide beneficial information and foundation for decision-makers and resource managers.
