Predicting Historical Populations and Evaluating Shifting Baselines of Traditionally Exploited Fisheries

Fish and Fisheries, EarlyView.
ABSTRACT Development of data‐intensive stock assessment and ecosystem‐based models has improved our understanding of shifting species abundance in response to fishing, ocean ecology, and species interactions. Along with this analytical progress is evidence that many stocks lack data required for complex models, resulting in data‐limited options for ...

Length‐Based Assessment of the Seven Most Commonly Caught Coral Reef Fish Species to Support Improve Management of Small‐Scale Fisheries in Southwest Madagascar

Aquaculture, Fish and Fisheries
The status of most fish stocks in Madagascar remains poorly documented. Given their importance for food security and livelihoods, it is necessary to define management measures with reliable data.

Unnatural Oceans

Scientia Marina, 2001
Ecological understanding of the oceans is based on an unnatural mix of mostly small species whose trophic relations are distorted to an unknown degree by the overfishing of megafauna including sharks, sea turtles, sea cows, seals, and whales.

Science-Based Management of America's Ocean Fish: A Growing Success Story [PDF]

, 2011
The United States is on the verge of completing a new science-based management system for ocean fish that will ensure sustainable fisheries. Congress should support managers as they achieve this goal, which will deliver an enduring legacy of healthy fish

Assessing the Progress of Stock Rebuilding in the Northeast Atlantic Against Levels That Can Produce Maximum Sustainable Yield

Fish and Fisheries, EarlyView.
ABSTRACT Rebuilding fish stocks to levels above which they produce Maximum Sustainable Yield (MSY) is a management aim for all European commercially exploited stocks. Progress is typically monitored against the fishing mortality that produces MSY in the long term (FMSY), however, the corresponding biomass target (BMSY) is rarely evaluated nor reported.

The Contested Commons: The Failure of EU Fisheries Policy and Governance in the Mediterranean and the Crisis Enveloping the Small-Scale Fisheries of Malta

Frontiers in Marine Science, 2018
This paper highlights how multi-scalar interstitial policy failings of the EU fisheries policy can directly trigger policy gaps in fisheries management at the expense of artisanal communities, leading to further expansion opportunities for industrial ...

Overfishing destroying livelihoods

Africa Renewal, 2017
It was midnight on 14 December 2016, when five fishermen in Tombo village near Freetown in Sierra Leone revved up a small outboard engine and powered their boat far out to sea. They threw in their net and soon bagged a good quantity of fish. But as they hauled in their catch, a terrible storm blew in.

Global Analysis of Shallow Underwater Fish Observation Research: 70 Years of Progress, Persistent Geographic Biases and a Path Forward

Fish and Fisheries, EarlyView.
ABSTRACT Marine ecosystems are increasingly threatened by overfishing, pollution, coastal development and climate change, underscoring the need for long‐term, representative information on key fish populations and habitats to inform management and policy.

The Abrupt and Persistent Decline in Recruitment Success in Northeast Arctic Cod: A Review of Probable Causes

Fish and Fisheries, EarlyView.
ABSTRACT Most of the previously large cod stocks in the North Atlantic are depleted to very low levels. A notable exception has been the Northeast Arctic cod inhabiting the Barents Sea. This cod stock reached a record high level around 2013, but since then has declined sharply, with older fish being fished out and few new recruits entering the stock ...
