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

Evidence for a fisher-designed solution to manta and devil ray bycatch in tuna fisheries. [PDF]

Conserv Biol
Abstract Bycatch in global tropical tuna purse seine fisheries represents a significant source of mortality for manta and devil rays (mobulids), which are globally threatened. Use of best handling and rapid release practices on purse seine vessels can substantially reduce mortality and improve vulnerability status for mobulids.

Why study bycatch? An introduction to the Theme Section on fisheries bycatch [PDF]

Endangered Species Research, 2008
Several high-profile examples of fisheries bycatch involving marine megafauna (e.g. dolphins in tuna purse-seines, albatrosses in pelagic longlines, sea turtles in shrimp trawls) have drawn attention to the unintentional capture of non-target species during fishing operations, and have resulted in a dramatic increase in bycatch research over the past 2

Seabird bycatch in a Baltic coastal gillnet fishery is orders of magnitude larger than official reports

Avian Conservation and Ecology, 2022
Bycatch, or the incidental capture of non-target species in fisheries, has been identified as one of the major threats affecting seabird populations worldwide.

Assessment of Australian Sea Lion Bycatch Mortality in a Gillnet Fishery, and Implementation and Evaluation of an Effective Mitigation Strategy

Frontiers in Marine Science, 2022
Globally, the bycatch of marine mammals in fisheries represents the greatest source of human-caused mortality that threatens the sustainability of many populations and species.

Bycatch Quotas, Risk Pools, and Cooperation in the Pacific Whiting Fishery

Frontiers in Marine Science, 2019
The United States Pacific whiting fishery uses mid-water trawl gear to target Pacific whiting off the United States West Coast. The fishery is subject to sector-specific bycatch caps for Chinook salmon (Oncorhynchus tshawytscha) and several rockfish ...

Bycatch in the Maldivian pole-and-line tuna fishery. [PDF]

PLoS ONE, 2017
Tropical tuna fisheries are among the largest worldwide, with some having significant bycatch issues. However, pole-and-line tuna fisheries are widely believed to have low bycatch rates, although these have rarely been quantified.

Estimating Bycatch Mortality for Marine Mammals: Concepts and Best Practices

Frontiers in Marine Science, 2021
Fisheries bycatch is the greatest current source of human-caused deaths of marine mammals worldwide, with severe impacts on the health and viability of many populations.

Bycatch species distribution from mid-water trawlers in the north-eastern Arabian sea: a step towards the implementation of marine spatial planning

Journal of Maps, 2023
Spatial conservation planning to reduce the impact of fishing on ecosystems necessitates understanding of the spatial distribution of bycatch in fishing grounds.

Spatial segregation and bycatch risk as potential drivers of population trends of wandering albatrosses at South Georgia. [PDF]

Conserv Biol
Abstract Spatial segregation in at‐sea distribution is frequently observed in seabirds and can have important implications for conservation and management. Globally, many albatross and petrel populations are declining due to bycatch in fisheries. In South Georgia, the decrease in wandering albatrosses (Diomedea exulans) differs among breeding sites ...
