Body Condition as a Shared Response to Environment in a Commercially Important Demersal Fish Assemblage

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Measures of an organism's weight at a given length are often considered reliable indicators of energy reserves or ‘condition’, which can be related to fecundity and risk of mortality. Understanding the impact of environmental change on fish condition may therefore inform sustainable management of human activities in marine ecosystems.

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

open access: yesFish 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.

Diets of shags Phalacrocorax aristotelis and cormorants P. carbo in Norway and possible implications for gadoid stock recruitment [PDF]

open access: yes, 1990
The diets of shags and cormorants were studied in Norway through analyses of regurgitated pellets. Although this method has many limitations, indications were that both species rely heavily on small gadoids (Gadidae) and sand eels (Ammodytidae) for food ...

Assessment of a Baited Remote Underwater Video Method to Evaluate American Lobster (Homarus americanus) Response to Baits in Nature

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT The American Lobster (Homarus americanus) is the target of an extensive fishery in the Northwest Atlantic, yet there is no systematic method for evaluating relative performance of baits for the fishery. We used Baited Remote Underwater Video (BRUV) to assess lobster attraction to commercial baits versus natural prey.
