Abstract
En 中文
This paper presents a systematic review of recent research advances and practical applications of electronic monitoring systems (EMS) in tuna longline fisheries; with the aim of addressing persistent challenges in fisheries monitoring; including limited human observer coverage and constraints related to data quality and data timeliness. The technological evolution of EMS is examined from three key perspectives: hardware infrastructure; algorithm development; and system architecture. In addition; regional differences in technological implementation and governance frameworks are comparatively analyzed across major fishing regions; including the European Union; North America; Pacific Island countries; and China.Building on this analysis; the review further evaluates the principal challenges affecting EMS deployment; particularly those associated with environmental robustness; data processing capacity; operational costs; and stakeholder acceptance. Finally; with reference to the regulatory requirements established by Regional Fisheries Management Organizations (RFMOs) and the developmental needs of China’s distant-water fisheries; the paper proposes targeted recommendations from the perspectives of technological innovation and institutional framework optimization. These recommendations aim to facilitate the transition of EMS from a data-recording tool to an intelligent decision-support platform; thereby providing a scientific reference for the sustainable management and governance of China’s tuna longline fisheries.
