Comparing Dynamic and Static Time-Area Closures for Bycatch Mitigation: A Management Strategy Evaluation of a Swordfish Fishery

Frontiers in Marine Science, 2021
Time-area closures are a valuable tool for mitigating fisheries bycatch. There is increasing recognition that dynamic closures, which have boundaries that vary across space and time, can be more effective than static closures at protecting mobile species

An overview on elasmobranch release as a bycatch mitigation strategy

ICES Journal of Marine Science, 2022
AbstractSharks and rays are among the most threatened vertebrates, mostly due to commercial fisheries. Data on incidental capture is sparse, but it is estimated that about 50% of reported global catches of elasmobranchs are from bycatch. Elasmobranchs are captured in a variety of fishing gear throughout the world.

Reducing Bycatch in Offshore Commercial Fisheries: Stakeholder Perspectives on Mitigation Measures

Society & Natural Resources
Reducing fisheries bycatch is a global challenge, with social factors playing a significant role in the adoption of mitigation measures (MMs). This study investigates these factors within Argentina’s offshore commercial bottom trawl fleet, where research remains limited. Through a qualitative approach, 29 interviews with key stakeholders were conducted

Getting to the bottom of bycatch: a GIS-based toolbox to assess the risk of marine mammal bycatch

Endangered Species Research, 2020
Marine mammal bycatch poses a particular challenge in developing countries, where data to document bycatch and its effects are often lacking. Using the Bycatch Risk Assessment (ByRA) toolkit, based on InVEST open-source models, we chose 4 field sites in ...

Review of bycatch mitigation measures in tuna longline fishery

NIPPON SUISAN GAKKAISHI, 2010
This review classiˆes and explains the bycatch mitigation measures in tuna longline ˆshery based on theirfunctional mechanism across bycatch species. In longline ˆshery bycatch mortality occurs through a commonprocess that typically follows these stages: 1) ˆshing operations overlap with the distribution of non-targetanimals; 2) non-target animals ...

Trends in marine species distribution models: a review of methodological advances and future challenges

Ecography, EarlyView.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Beyond Post-release Mortality: Inferences on Recovery Periods and Natural Mortality From Electronic Tagging Data for Discarded Lamnid Sharks

Frontiers in Marine Science, 2021
Accurately characterizing the biology of a pelagic shark species is critical when assessing its status and resilience to fishing pressure. Natural mortality (M) is well known to be a key parameter determining productivity and resilience, but also one for

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

Environmental Toxicology, EarlyView.
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.

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...
