Reliability of self-reported catch and effort data via smartphone applications in a multi-species recreational fishery

This study evaluates a smartphone app for self-reporting fishing data in a recreational fishery, comparing it to traditional creel surveys and finding mixed reliability across metrics and species.

On the imbalance between production and exploitation of marine fish assemblages: a case study from the Celtic Seas

The paper examines the exploitation ratios of demersal fish species in the Celtic Seas and finds no evidence that rarer species have lower exploitation ratios than common ones, suggesting current management methods are insufficient for conserving the assemblage as a whole.

Temperature variation and life history mediate the degree of nonlinearity in fluctuations of global marine fish populations

The paper examines how temperature variation and life history traits influence nonlinearity in marine fish population fluctuations, finding temperature amplifies nonlinearity while life history dampens it in slow-lived species.

The paper analyzes 40 years of North Sea Atlantic cod abundance data to assess population stability changes, finding reduced resilience and altered age group dynamics post-2000 decline.

Exploring mechanisms of change in a Southern Ocean fishery with a co-produced network model

The paper develops a co-produced network model to explore potential pathways of decline and increase in a Patagonian toothfish fishery under climate change and fishery trends.

Integrating eDNA and acoustic-trawl data to provide small pelagic biomass estimates for fisheries assessment

This paper combines eDNA and acoustic-trawl data using a Bayesian joint model to estimate fish biomass, showing eDNA suggests broader distribution and potentially higher abundance of European anchovy.

Validating Atlantic salmon (Salmo Salar) scale reading by genetic parent assignment and PIT-tagging

This paper validates Atlantic salmon scale reading using genetic parent assignment and PIT-tagging, finding high accuracy for sea-age but lower for freshwater-age and discrepancies in back-calculated smolt length.

Mapping climate risks across global pelagic fishing grounds

The paper identifies global hotspots of climate-driven fish biomass decline risks by integrating biomass projections, fishing effort, and socioeconomic vulnerability.

Diet predicts performance trade-offs during Atlantic salmon ontogeny

This study shows that diet affects performance trade-offs in Atlantic salmon during their marine stage, with age-dependent impacts on condition factor and maturation age.

Changing food conditions and size declines in a North Sea forage fish

This study identifies declining prey densities as the main driver of size declines in lesser sandeel in the North Sea, while temperature effects are smaller and context-dependent.

'surveyjoin': A Standardized Database of Fisheries Bottom Trawl Surveys in the Northeast Pacific Ocean

The paper introduces surveyjoin, a database and R package that standardizes and integrates bottom trawl survey data from the Northeast Pacific Ocean to improve fisheries management and ecosystem assessments.

Treading lightly: Quantitative estimates of seafloor contact for longline trap and hook fishing gear

This paper quantifies bottom contact areas of longline fishing gear in the Sablefish fishery, finding low habitat risk due to minimal contact in most areas.

Environmental and anthropogenic impacts on key fish and mollusc species of the Mediterranean Sea from the Late Pleistocene until the Industrial Revolution

This study examines changes in fish and mollusc species in the Mediterranean Sea from 130,000 years ago to the Industrial Revolution, showing environmental and human impacts on their abundance and size.

Managing risks and trade-offs in multispecies fisheries: the role of trophic control and price asymmetry

This study examines fishing strategies in multispecies fisheries, showing predators are more affected by fishing than prey, and high yields come with ecological trade-offs and risks.
