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

Rapid Assessments of Leatherback Small-Scale Fishery Bycatch in Internesting Areas in the Eastern Pacific Ocean

Frontiers in Marine Science, 2020
The East Pacific (EP) leatherback population is listed by the IUCN Red List of Threatened Species as Critically Endangered. Despite conservation efforts, mainly focused on nesting beaches, its population has declined by over 90% since the 1980s.

A socio‐psychological approach for understanding and managing bycatch in small‐scale fisheries

People and Nature, 2023
Fisheries bycatch is the greatest threat to migratory, long‐lived marine animals. Addressing bycatch ultimately requires changing fisher behaviour, yet social and behavioural sciences are rarely applied to bycatch mitigation, with an absence of theory ...

Supplementary material: Knowing the fishery to know the bycatch from Knowing the fishery to know the bycatch: bias-corrected estimates of harbour porpoise bycatch in gillnet fisheries

, 2023
Incidental captures (bycatch) remain a key global conservation threat for cetaceans. Bycatch of harbour porpoise Phocoena phocoena in set gillnets is routinely monitored in European Union fisheries, but generally relies on data collected at low spatio-temporal resolution or over short periods.

To ping or not to ping : the use of active acoustic devices in mitigating interactions between small cetaceans and gillnet fisheries [PDF]

, 2013
Active sound emitters (‘pingers’) are used in several gillnet fisheries to reduce bycatch of small cetaceans, and/or to reduce depredation by dolphins. Here, we review studies conducted to determine how effective these devices may be as management tools.

An investigation of factors related to the bycatch of small cetaceans in fishing gear [PDF]

, 2011
The bycatch of cetaceans in fishing gear is considered to be one of the biggest conservation threats to these species. Gear modifications have the potential to reduce these bycatches in global fisheries but there is little available information on how ...

Disentangling the causes of protected‐species bycatch in gillnet fisheries [PDF]

Conservation Biology, 2017
Abstract Gillnet fisheries are widely thought to pose a conservation threat to many populations of marine mammals, seabirds, and turtles. Gillnet fisheries also support a significant proportion of small‐scale fishing communities worldwide. Despite a large number of studies on protected‐species bycatch in recent decades, relatively few

Evaluating the potential effectiveness of compensatory mitigation strategies for marine bycatch. [PDF]

PLoS ONE, 2008
Conservationists are continually seeking new strategies to reverse population declines and safeguard against species extinctions. Here we evaluate the potential efficacy of a recently proposed approach to offset a major anthropogenic threat to many ...

The bycatch composition of shrimp trawl fishery in the Oman coastal waters, the Arabian Sea [PDF]

Acta Ichthyologica et Piscatoria, 2015
Background. Shrimps are one of the most valuable marine resources of Oman and shrimp fisheries is greatly contributing to the national economy, and sustainability of traditional fisheries villages. However, the shrimp trawl fishery has one of the highest

Estimating Bycatch From Non-representative Samples (II): A Case Study of Pair Trawlers and Common Dolphins in the Bay of Biscay

Frontiers in Marine Science, 2022
Marine megafauna plays an important functional role in marine ecosystems as top predators but are threatened by a wide range of anthropogenic activities. Bycatch, the incidental capture of non-targeted species in commercial and recreational fisheries, is
