Foraging activity of harbour porpoises around a bottom-gillnet in a coastal fishing ground, under the risk of bycatch.

PLoS ONE, 2021
Bycatch of harbour porpoises (Phocoena phocoena) by gillnets is a recognised threat to populations. To develop effective mitigation measures, understanding the mechanics of bycatch is essential.

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

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.

Predicting bycatch hotspots in tropical tuna purse seine fisheries at the basin scale

Global Ecology and Conservation, 2020
Fisheries observer programs represent the most reliable way to collect data on fisheries bycatch. However, their limited coverage leads to important data gaps that preclude bycatch mitigation at the basin scale.

Acoustic deterrence to facilitate the conservation of pantropical spotted dolphins (Stenella attenuata) in the Western Pacific Ocean

Frontiers in Marine Science, 2022
Commercial fishing constitutes an important food source but induces undesirable bycatch on animals worldwide. This study extends bycatch research geographically to the Western Pacific Ocean, filling a knowledge gap regarding bycatch and mitigation ...

Best Practices for Assessing and Managing Bycatch of Marine Mammals

Frontiers in Marine Science, 2021
Bycatch in marine fisheries is the leading source of human-caused mortality for marine mammals, has contributed to substantial declines of many marine mammal populations and species, and the extinction of at least one.

Addressing fisheries bycatch in a changing world

Frontiers in Marine Science, 2015
Fisheries bycatch is a threat to species of marine megafauna across the world’s oceans. Work over the past several decades has greatly advanced our understanding of the species affected, the magnitude and the spatial extent of bycatch.

Cetacean bycatch management in regional fisheries management organizations: Current progress, gaps, and looking ahead

Frontiers in Marine Science, 2023
Bycatch is the leading global threat to cetaceans, with at least 300,000 cetaceans estimated to be killed each year in fisheries. Regional fisheries management organizations (RFMOs) are key actors in global fisheries management, including bycatch ...

Bycatch and discards: from improved knowledge to mitigation programmes [PDF]

ICES Journal of Marine Science, 2014
Abstract Discarding is considered by many as an important problem in world fisheries. In many regions, data collection onboard commercial vessels has intensified, and the understanding of both human and ecological drivers of discards is improving quickly.

Integrating fishers’ knowledge contributions in Marine Science to tackle bycatch in the Bay of Biscay

Frontiers in Marine Science, 2022
The issue of bycatch is raising considerable political, mediatic and scientific attention. Bycatch is one of the main causes of at-sea mortality for small cetacean species and for seabirds. Scientists are raising alerts regarding the potential effects on
