Trace Element Contamination in Top Predatory Elasmobranchs From the Southern Black Sea: Implications for Ecosystem Health and Risk Assessment

Environmental Toxicology, EarlyView.
ABSTRACT Environmental pollution resulting from the rapid increase in human population, urbanization, intensive use of chemicals in agriculture, and industrial development has reached a level that threatens natural life today. Trace elements are one of the most important factors causing significant levels of pollution in the environment and are added ...

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 ...

Market Systems Integration in Zambia's Aquaculture Sector: A Scoping Review of Value Chains, Supply Chains and Sustainability Challenges

Aquaculture, Fish and Fisheries, Volume 6, Issue 5, October 2026.
ABSTRACT Aquaculture is increasingly important to food security, nutrition, livelihoods and economic development in Zambia, yet sectoral growth depends on more than production capacity. This scoping review synthesised evidence on Zambia's aquaculture market systems, focusing on value chains, supply chains and persistent evidence gaps.
