Lessons for stock assessment from the northern cod collapse
@article{Walters2004LessonsFS, title={Lessons for stock assessment from the northern cod collapse}, author={Carl J. Walters and Jean-Jacques Maguire}, journal={Reviews in Fish Biology and Fisheries}, year={2004}, volume={6}, pages={125-137} }
Fisheries assessment scientists can learn at least three lessons from the collapse of the northern cod off Newfoundland: (1) assessment errors can contribute to overfishing through optimistic long-term forecasts leading to the build-up of overcapacity or through optimistic assessments which lead to TACs being set higher than they should; (2) stock size overestimation is a major risk when commercial catch per effort is used as an abundance trend index, so there is continued need to invest in…

Recovery of assessed global fish stocks remains uncertain
- Environmental ScienceProceedings of the National Academy of Sciences
- 2021
It is shown that different methods produce markedly divergent trajectories of global fisheries status, with 4 of 10 methods suggesting that recovery has not yet been achieved, with up to 48% of individual stocks remaining below biomass targets and 40% exploited above sustainable rates.
Eastern Baltic cod in distress: biological changes and challenges for stock assessment
- Environmental Science
- 2015
The eastern Baltic (EB) cod (Gadus morhua) stock was depleted and overexploited for decades until the mid-2000s, when fishing mortality rapidly declined and biomass started to increase, as shown by…
The assessment of fishery status depends on fish habitats

At the crux of the debate over the global sustainability of fisheries is what society must do to prevent over‐exploitation and aid recovery of fisheries that have historically been over‐exploited.…
Risk of collapse in the eastern Baltic cod fishery
- Environmental Science
- 2002
Results show that the current fishing mortality implies a tremendous risk of driving the Baltic cod stock below Bext (1000 t) within 10 yr, which is robust to alternative assumptions about model structure and the magnitude of environmental stochasticity.
Annual trends in catchability and fish stock assessments
- Environmental Science
- 2003
A key assumption of many fish stock assessment models is that catchability is constant over time. We assume here that trends in catchability may occur through fishing power creeping. The tuning…

Uncertainty in stock assessment estimates for New England groundfish and its impact on achieving target harvest rates.

Overfishing continues for many stocks in the New England groundfish complex despite efforts to constrain harvest rates and rebuild populations. We evaluated the magnitude and sources of scientific…
The assessment of fishery status depends on the condition of fish habitats

This work conceptualise how the classification of stock status can be biased by habitat change, and suggests the role of habitat should be considered when assessing the global status of fisheries.

Fisheries for small pelagic species: an empirical approach to management targets
- Environmental ScienceReviews in Fish Biology and Fisheries
- 2004
A simple model was fitted to medium-term periods in exploited small pelagic fisheries, relating change in stock biomass to exploitation rate and appeared to be in equilibrium for an exploitation rate F/Z=0.4, which may be used as a guideline for the appropriate exploitation of pelagic stocks.
What can be learned from the collapse of a renewable resource? Atlantic cod, Gadus morhua, of Newfoundland and Labrador
- Environmental Science
- 1994
Temporal changes in demography, population sustainability, and harvest rates support the hypothesis that overexploitation precipitated the commercial extinction of northern cod, Gadus morhua, off Newfoundland and Labrador in 1992 and reject hypotheses that attribute the collapse of northernCod to environmental change.

Fish distribution and catchability : what is the appropriate measure of distribution ?
- Environmental Science
- 1994
It is shown that spatially uniform changes in abundance can affect catchability given certain models for the distribution of fishing effort, but that this effect is slight compared with the effect of changes in the spatial spread of fish distribution.

Evidence from existing marine reserves indicates that increased abundance, individual size, reproductive output, and species diversity occurred in a variety of marine species in refuges of various sizes, shapes, and histories in communities ranging from coral reefs to temperate kelp forests.
Trends in Catch, Age, and Size of Cod from the Commercial Longline Fishery at Bonavista, Newfoundland, 1952–62

A commercial longline fishery for cod was begun from Bonavista in 1952 but thereafter decreased rapidly because of the intense fishery, especially by European otter-trawlers and longliners after 1956, and irregular recruitment to the fishery.
