Spatial and temporal variations in seabird bycatch: Incidental bycatch in the Norwegian coastal gillnet-fishery.

open access: yesPLoS ONE, 2019
The general decline of seabird populations worldwide raises large concerns. Although multiple factors are interacting to cause the observed trends, increased mortality from incidental bycatch in fisheries has proven to be important for many species ...

Genetic assignment of fisheries bycatch reveals disproportionate mortality among Alaska Northern Fulmar breeding colonies

open access: yesEvolutionary Applications, 2022
Global fisheries kill millions of seabirds annually through bycatch, but little is known about population‐level impacts, particularly in species that form metapopulations. U.S.

Advances in Scale Assessment of Seabird Bycatch: A New Methodological Framework

open access: yesDiversity, 2023
This paper presents a methodology for indirectly estimating the scale of seabird bycatch using existing data. The study focuses on five key species of ducks that winter in the Polish waters of the Baltic Sea and are highly susceptible to bycatch: Long ...

Marine mammal bycatch in gillnet and other entangling net fisheries, 1990 to 2011

open access: yesEndangered Species Research, 2013
Since the 1970s the role of fishery bycatch as a factor reducing, or limiting the recovery of, marine mammal populations has been increasingly recognized.

Comparing Dynamic and Static Time-Area Closures for Bycatch Mitigation: A Management Strategy Evaluation of a Swordfish Fishery

open access: yesFrontiers 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

Catch, bycatch and discards of the Galapagos Marine Reserve small-scale handline fishery [PDF]

open access: yesPeerJ, 2015
Fisheries bycatch is a significant marine conservation issue as valuable fish are wasted and protected species harmed with potential negative ecological and socio-economic consequences.

Addressing fisheries bycatch in a changing world

open access: yesFrontiers 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.

Influence of nearby environment on recreational bycatch of sea turtles at fishing piers in the eastern Gulf of Mexico

open access: yesEndangered Species Research, 2023
Incidental bycatch of sea turtles from recreational fisheries is generally undocumented globally. At Gulf of Mexico fishing piers in the USA, bycatch is a source of injury and potential mortality of sea turtles.

Bycatch and Bycatch Reduction in Recreational Shrimping

open access: yesNortheast Gulf Science, 1994
We estimated the bycatch from recreational shrimping by quantifying the catch from fishery independent trawling and through a survey of licensed recreational shrimpers in Alabama during 1990. We used paired trawls to test two net modifications (fish shooter and Florida flsheye) for bycatch reduction.

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

open access: yesBirds, 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
