Mismatches between genetic and assessment units in commercial fish species: A systematic review in the North‐East Atlantic

Journal of Fish Biology, EarlyView.
Abstract While sustainable fisheries depend upon spatial and temporal identification at below the species level (i.e., stock units), the choice and identification of appropriate units remain challenging. Advances in DNA sequencing and improved computational power have generated extensive genetic and genomic data on the spatio‐temporal dynamics and ...

Revealing potential Atlantic salmon bycatch hotspots from pelagic fisheries landings across the Northeast Atlantic

Journal of Fish Biology, EarlyView.
Abstract Atlantic salmon (Salmo salar) marine survival has declined markedly over the past five decades, leading to concerns about future population viability. While many studies have explored the impacts of stressors such as climate change and predation, less is known about bycatch from pelagic fisheries targeting finfish species.

An Optimal Control Framework for Multi‐Species Harvesting in the Southern Black Sea

Natural Resource Modeling, Volume 39, Issue 4, November 2026.
ABSTRACT The management of marine fisheries requires balancing ecological sustainability with economic profitability, particularly in ecosystems vulnerable to overexploitation. This study develops a multi‐species optimal control modeling framework for the southern Black Sea, focusing on three key species: horse mackerel (Trachurus mediterraneus) as ...

Recreational Fisheries in Türkiye: Socio‐Economic Profiles, Technological Trends and Governance Challenges

Fisheries Management and Ecology, Volume 33, Issue 5, Page 1057-1070, October 2026.
ABSTRACT Recreational fisheries in Türkiye constitute an understudied socio‐economic sector spanning marine and freshwater ecosystems across the Mediterranean and Black Sea basins, yet robust national participation estimates remain constrained by the absence of a comprehensive registry or probability‐based sampling frame.
