Mitigating seabird bycatch during hauling by pelagic longline vessels. [PDF]

PLoS ONE, 2014
Bycatch in longline fisheries threatens the viability of some seabird populations. The Hawaii longline swordfish fishery reduced seabird captures by an order of magnitude primarily through mitigating bycatch during setting.

Risk Factors for Seabird Bycatch in a Pelagic Longline Tuna Fishery. [PDF]

PLoS ONE, 2016
Capture in global pelagic longline fisheries threatens the viability of some seabird populations. The Hawaii longline tuna fishery annually catches hundreds of seabirds, primarily Laysan (Phoebastria immutabilis) and black-footed (P.

Biodiversity offsets: a cost-effective interim solution to seabird bycatch in fisheries? [PDF]

PLoS ONE, 2011
The concept of biodiversity offsets is well established as an approach to environmental management. The concept has been suggested for environmental management in fisheries, particularly in relation to the substantial numbers of non-target species ...

Seabird bycatch in pelagic longline fisheries is grossly underestimated when using only haul data. [PDF]

PLoS ONE, 2010
Hundreds of thousands of seabirds are killed each year as bycatch in longline fisheries. Seabirds are predominantly caught during line setting but bycatch is generally recorded during line hauling, many hours after birds are caught. Bird loss during this

Altering gillnet soak duration and timing minimizes bycatch and maintains target catch. [PDF]

PLoS ONE
Seabirds are one of the most at-risk avian groups worldwide, and incidental catch in fishing practices is one of the top threats for seabirds globally.

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

Evolutionary 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.

The Development of DNA Markers to Resolve Uncertainties of Seabird Bycatch Identification From Longline Fisheries in Australian Waters [PDF]

Ecology and Evolution
Incidental mortality in fisheries is a major driver of population declines for albatrosses and petrels globally. However, accurate identification of species can be difficult due to the poor condition of bycaught birds and/or visual similarities between ...

Use of rapid assessments of fishery bycatch of Humboldt penguins Spheniscus humboldti in Peru and Chile to help identify conservation priorities [PDF]

Royal Society Open Science
The Humboldt penguin (Spheniscus humboldti) is a threatened species endemic to the Humboldt current system along the coasts of Peru and Chile. The species faces numerous and significant threats contributing to its declining population among which one of ...

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 ...

A multiscale seasonal examination of the risk of harm to seabirds from vessels based on co-occurrence in Alaskan waters. [PDF]

Conserv Biol
Abstract Alaska's seascape supports globally significant seabird populations, including vulnerable and threatened species, and hosts economically important commercial fisheries and marine transportation corridors. Seasonal patterns of seabird movements and vessel traffic create a complex landscape of risk, defined as high levels of co‐occurrence ...
