Signatures of the collapse and incipient recovery of an overexploited marine ecosystem [PDF]

Royal Society Open Science, 2017
The Northwest Atlantic cod stocks collapsed in the early 1990s and have yet to recover, despite the subsequent establishment of a continuing fishing moratorium.

Paper Fish and Policy Conflict: Catch Shares and Ecosystem-Based Management in Maine's Groundfishery

Ecology and Society, 2011
The National Oceanic and Atmospheric Administration professes support for ecosystem-based fisheries management, as mandated by Congress in the Fishery Conservation and Management Act, and as endorsed by the Obama Administration's national ocean policy ...

Fisheries co-management in a digital age? An investigation of social media communications on the development of electronic monitoring for the Northeast U.S. groundfish fishery

Ecology and Society, 2022
Fisheries regulators have increasingly incorporated video monitoring systems, also known as electronic monitoring, into programs for fisheries data collection and documentation of bycatch.

Beta diversity of demersal fish assemblages in the North-Eastern Pacific: interactions of latitude and depth. [PDF]

PLoS ONE, 2013
Knowledge of broad-scale global patterns in beta diversity (i.e., variation or turnover in identities of species) for marine systems is in its infancy. We analysed the beta diversity of groundfish communities along the North American Pacific coast, from ...

Assessing the State of Demersal Fish to Address Formal Ecosystem Based Management Needs: Making Fisheries Independent Trawl Survey Data ‘Fit for Purpose’

Frontiers in Marine Science, 2019
In Europe, introduction of the Marine Strategy Framework Directive (MSFD) represents formal, legally-binding, adoption of ecosystem-based management (EBM) across most European waters.

Marine Ecosystem Variations Over the North Pacific and Their Linkage to Large-Scale Climate Variability and Change

Frontiers in Marine Science, 2020
In order to understand how North Pacific (NP) marine ecosystems have varied, 120 marine biological time series for both the western (29 time series) and eastern (91 time series) NP were analyzed with a Principal Component Analysis (PCA) for the period ...

Bottom–Up Impacts of Forecasted Climate Change on the Eastern Bering Sea Food Web

Frontiers in Marine Science, 2021
Recent observations of record low winter sea-ice coverage and warming water temperatures in the eastern Bering Sea have signaled the potential impacts of climate change on this ecosystem, which have implications for commercial fisheries production.

Inferring fish behaviour at the trawl mouth from escape location [PDF]

PeerJ, 2023
In this study, we used escape location underneath the trawl to understand groundfish herding behaviour at the trawl mouth. Three collecting bags (port, center, starboard) were mounted under the trawl and behind the footgear to collect escapees.

Spatio-Temporal Dynamics of Exploited Groundfish Species Assemblages Faced to Environmental and Fishing Forcings: Insights from the Mauritanian Exclusive Economic Zone. [PDF]

PLoS ONE, 2015
Environmental changes and human activities can have strong impacts on biodiversity and ecosystem functioning. This study investigates how, from a quantitative point of view, simultaneously both environmental and anthropogenic factors affect species ...
