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.

Estimating common dolphin bycatch in the pole-and-line tuna fishery in the Azores [PDF]

PeerJ, 2018
Small-scale artisanal fisheries can have a significant negative impact in cetacean populations. Cetacean bycatch has been documented in the pole-and-line tuna fishery in the Azores with common dolphins being the species more frequently taken.

Assessing the Uncertainty of Total Seabird Bycatch Estimates Synthesized from Multiple Sources with a Scenario Analysis from the Western and Central Pacific

Birds, 2022
Each year, billions of seabirds undertake migrations, connecting remote regions of the world, potentially synchronizing population fluctuations among distant areas. This connectedness has implications for the uncertainty calculations of the total seabird

Looming-eyes buoys fail to reduce seabird bycatch in the Icelandic lumpfish fishery: depth-based fishing restrictions are an alternative

Royal Society Open Science, 2023
Bycatch in gillnets from lumpfish (Cyclopterus lumpus) fisheries is an important conservation issue in the north Atlantic, with up to 30 000 seabirds potentially killed each year. To date, no technical solutions exist to reduce the bycatch of seabirds in

Bycatch in Indian trawl fisheries and some suggestions for trawl bycatch mitigation

Current Science, 2022
Globally, trawl is the major fishing gear used in marine fisheries and in India, it contributes to more than onethird of the marine fish production. Trawl fishing has been critically evaluated from a sustainability perspective, especially analysing its bycatch composition.

How much do we know about seabird bycatch in pelagic longline fisheries? A simulation study on the potential bias caused by the usually unobserved portion of seabird bycatch.

PLoS ONE, 2019
Not much is known about the fleet level total seabird bycatch from pelagic longlines of United States vessels in the western North Atlantic or other fleets of the Atlantic or other oceans.

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

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.

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
