Cooper Van Vranken, Berthe M.J. Vastenhoud, James P. Manning, Kristian S. Plet-Hansen, Julie Jakoboski, Patrick Gorringe, Michela Martinelli While the observation of the open ocean is well achieved by automated ocean measurement instruments, coastal and shelf seas suffer the lack of sub-surface collection platforms. Commercial fishing gear such as bottom trawls, pots, traps and long lines can …

Electronic Monitoring: Best Practices for Automation
To provide further support to groups progressing machine learning and automatic analysis, GMRI partnered with CVision AI to publish Electronic Monitoring: Best Practices for Automation, a first-of-its-kind Electronic Monitoring guidance document that describes best practices for designing EM systems and programs suited for automated or semi-automated video analysis. This document presents a broad …

EM trials and fully implemented programs on world map. Figure courtesy of van Helmond et al. 2019. Abstract Since the beginning of the 21st century, electronic monitoring (EM) has emerged as a cost‐efficient supplement to existing catch monitoring programmes in fisheries. An EM system consists of various activity sensors and cameras positioned on vessels to remotely record fishing activity …

Abstract: As human populations have more than doubled since 1960, pressure on wild fish stocks has increased dramatically. This Article argues that the establishment of an electronic reporting and monitoring regime in U.S. fisheries is both necessary to ensure compliance with statutory imperatives to manage them according to best available science, and essential for continued long-term viability …

Highlights Electronic Monitoring (EM) with video can measure discards with high precision. Technical developments have increased EM reliability Video audit time has been reduced via improved procedures and technical solutions. EM is a cost-effective tool to ensure compliance with discard regulations. Abstract: Electronic Monitoring (EM) with video is a tool often mentioned to …
