Participatory Risk Assessment of Humpback Whale (Megaptera novaeangliae) and Leatherback Turtle (Dermochelys coriacea) Bycatch in Northern Peru

Frontiers in Marine Science, 2021
Uncertainties about the magnitude of bycatch in poorly assessed fisheries impede effective conservation management. In northern Peru, small-scale fisheries (SSF) bycatch negatively impacts marine megafauna populations and the livelihoods of fishers which

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.

Relative abundance and distribution of fisheries influence risk of seabird bycatch [PDF]

, 2016
Fisheries provide an abundant and predictable food source for many pelagic seabirds through discards, but also pose a major threat to them through bycatch, threatening their populations worldwide. The reform of the European Common Fisheries Policy (CFP),

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 ...

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
