Spatial density and habitat associations of Atlantic Cod on the Northeastern US Continental Shelf

This study uses VAST models to analyze spatial density and habitat associations of Atlantic cod on the Northeastern US Continental Shelf from 1982 to 2021, finding strong associations with depth, temperature, and gravel sediments.

Influence of predation mortality on past and future dynamics of Pacific Herring: implications for stock status and future biomass

This study evaluates how increasing marine mammal predation affects Pacific Herring population dynamics and forecasts future biomass using integrated ecological models.

Accounting for salmon body size declines in fishery management can reduce conservation risks

This study shows that accounting for declining salmon body size in fishery management can reduce conservation risks and increase run sizes by up to 25%.

Understanding organism-habitat relationships and critically evaluating reference areas is key to marine protected area assessment

The paper evaluates how protection status and environmental conditions affect fish abundance and biomass in marine protected areas, finding depth and habitat are strong predictors, but protection effects vary by species.

Rapid ecosystem change after the cod collapse in Newfoundland & Labrador

The paper models ecosystem changes in Newfoundland & Labrador after the cod collapse, showing shifts in biomass and species dominance, with capelin remaining low and Arctic cod becoming more prevalent.

Assessing the effects of female protections on size structure and spawning potential in two clawed lobster fisheries subject to varying exploitation levels

This study compares two lobster fisheries with different female protection strategies, finding that low fishing effort and protection of egg-bearing females enhance egg production but skew sex ratios and size structures.

Acoustic target strengths and swimbladder morphology of Chub mackerel Scomber japonicus in the Northwest Pacific Ocean

The paper measures acoustic target strengths and swimbladder morphology of chub mackerel to improve acoustic stock assessment in the Northwest Pacific Ocean.

Integrating fish biology, population genomics and fishery policies for informed management of interjurisdictional multi-species fisheries

The paper introduces IRIIS, a framework that integrates population genomics, fish biology, and fisheries policies to assess overexploitation risk in interjurisdictional fisheries.

Group composition and its ontogenetic changes in marine pelagic fishes

This study examines group composition and its ontogenetic changes in two marine fish species, finding that group structure shifts from age/growth-similar individuals in juveniles to more random composition in sub-adults.

Marine heatwaves disrupt ecosystem structure and function via altered food webs and energy flux

Pre- versus post-heatwave Ecotran food-web models of the Northern California Current show that newly abundant pyrosomes caused the largest energy-flux disruption, diverting lower-trophic energy mostly into detritus.

Bycatch mitigation of endangered marine life

This paper reviews 389 articles to assess the effectiveness of bycatch mitigation measures in fishing, finding pingers, TEDs, and BSLs most effective for marine mammals, sea turtles, and seabirds, respectively, while elasmobranchs remain challenging.

An updated end-to-end ecosystem model of the Northern California Current reflecting ecosystem changes due to recent marine heat waves

The paper updates an ecosystem model of the Northern California Current to reflect recent marine heat wave impacts and includes new data and species.

Mixed origin of juvenile Atlantic cod (Gadus morhua) along the Swedish west coast

This study genetically identifies juvenile Atlantic cod ecotypes along the Swedish west coast, revealing coastal dominance in inshore areas and offshore dominance in deeper waters.

How do tuna schools associate to dFADs? A study usingecho-sounder buoys to identify global patterns

The paper uses machine learning to analyze tuna school association with dFADs using echo-sounder buoy data, finding symmetric aggregation and disaggregation times across oceans.

Compositional forecasting of Chinook Salmon Evolutionarily Significant Units in bycatch for Pacific Hake fisheries

The paper develops predictive models to estimate proportions of Chinook Salmon ESUs in bycatch for Pacific Hake fisheries using genetic mixture analysis and regression methods.

Tuna-AI: tuna biomass estimation with Machine Learning models trained on oceanography and echosounder FAD data

This paper develops a Machine Learning model to estimate tuna biomass using oceanographic and echosounder FAD data.
