Associations of Commercial Fisheries and Cold‐Water Corals and Sponges
Three metrics for determining whether the marine life that are landed by commercial fisheries are associated with cold‐water corals and sponges: (a) Adjacent; (b) General Proximity; and (c) Habitat. The relationship between these structure forming invertebrates (SFI) and fisheries is robust across analytical approaches.

Seabird bycatch—particularly involving albatrosses and petrels—remains a significant conservation concern in pelagic longline fisheries. This study evaluated the effectiveness of three mitigation measures—bird-scaring lines (BSLs), weighted branch lines,

ABSTRACT Despite their potential to inform sustainable regional harvest and climate‐resilient fisheries management, spatial stock assessment models remain underused for management advice. To identify barriers that inhibit broader use of these methods, we conducted a blinded international simulation experiment mimicking real‐world stock assessment ...

Length-frequency estimation for yellowfin tuna (Thunnus albacares) caught by commercial fishing gear in the Eastern Pacific Ocean [PDF]
ENGLISH: Methods of collecting samples for the purpose of estimating the numbers and weights of fish caught, by length interval, are described. Several models for two-stage sampling are described, and the equations for the estimators and their variances ...

Chasing Fish: 130 Years of Innovation, Displacement and Depletion in Scottish Fisheries
ABSTRACT Rebuilding the depleted fisheries of the 21st century requires an understanding of past drivers of their decline. Despite Scotland's central role in the commercial exploitation of North Sea fisheries for over a century, associations between technological innovations, regulatory introductions and fishery landings have not previously been ...

Estimating mortality of sea turtles incidentally captured in fishing gear is essential to understanding fishery impacts on sea turtle populations. Loggerhead turtles (Caretta caretta) are a component of bycatch in pelagic longline fisheries, including ...

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.

Decarbonizing Fisheries Through Ensuring Healthy Stock Status
ABSTRACT Industrial capture fisheries depend on fossil fuels, which tend to dominate both greenhouse gas emissions and operational costs of this form of seafood production. Improving energy efficiency is, in addition to shifting to alternative fuels, a crucial path towards decarbonizing fisheries.
