Bycatch in bivalve fisheries of Algarve

, 2016
The present study assessed bycatch in Algarve grid dredge fisheries and estimated fishing gear inflicted damage and mortality, with the purpose of formulating mitigation measures, specifically fishing gear modifications. Bycatch using this dredge has been shown to surpass target species catch and, although it would not be a major problem if the ...

Study on the catch, bycatch and discard of Chinese pelagic longline fisheries in the Atlantic Ocean

Aquaculture and Fisheries
Catch, bycatch and discard information is important for the assessment and management of fisheries. Using Chinese pelagic tuna longline observer data from 2010 to 2018, we studied the catch composition in the Chinese pelagic tuna longline fisheries in ...

Seabird Prey in Space and Time: Combining Multiple Datasets to Model the Distribution of Sandeel (Ammodytes marinus) and Sprat (Sprattus sprattus) in the North Sea

Ecology and Evolution, Volume 16, Issue 11, November 2026.
Forage fish are key prey and commercial species in the North Sea ecosystem, but estimates of their biomass over detailed spatial and temporal scales is currently limited. To fill this vital research gap we employ Hierarchical Bayesian spatiotemporal models of sandeel (Ammodytes marinus) and sprat (Sprattus sprattus) in the North Sea, providing fine ...

Shark Bycatch in Commercial Fisheries: A Global Perspective [PDF]

, 2017
Many shark species have global distributions and are caught incidentally in different types of fisheries. Over the last two decades, shark populations have declined tremendously, with one of the leading causes of this decline bycatch in primarily ...

Test of light emitting diodes (LED) as a possible bycatch mitigation measure in a gillnet fishery

Global Ecology and Conservation
Substantial seabird bycatch occurs in North Atlantic lumpfish fisheries, potentially impacting seabird populations and raising concerns about the fisheries’ sustainability. Despite increased efforts to address this issue, existing approaches have yielded

Assessing the Health Impacts of Contaminants on Green Turtles (Chelonia mydas) Along the Southern Coast of Brazil

Environmental Toxicology, Volume 41, Issue 11, Page 1277-1288, November 2026.
ABSTRACT Chemical pollutants pose a significant threat to marine ecosystems. Among these contaminants are trace elements and polycyclic aromatic hydrocarbons (PAH). Green turtles can be employed to evaluate the oceans' health due to their coastal habitats and exposure to multiple threats.

Global Patterns in the Nutrient Composition Delivered by Seabirds to Coastal and Island Ecosystems

Global Ecology and Biogeography, Volume 35, Issue 11, November 2026.
ABSTRACT Aim Consumer‐mediated nutrient dynamics are crucial for sustaining ecosystems. While most research has focused on the magnitude of seabird‐derived nutrient fluxes, the role of species and diet composition in shaping nutrient quality remains largely unexplored.

Bycatch Avoidance Programs in Two New England (USA) Fisheries [PDF]

We conducted similar bycatch avoidance programs in two New England fisheries: yellowtail flounder bycatch in the sea scallop closed area fisheries and river herring bycatch in the Atlantic herring and mackerel fishery.
