Management Implications of Mesopelagic Forage Fisheries for Bigeye Tuna Stocks

Fisheries Management and Ecology, EarlyView.
ABSTRACT Many large marine predators forage on mesopelagic fish stocks, including commercially valuable tunas. The mesopelagic is under increasing interest for commercial exploitation, given its large biomass with potential to supply fishmeal for aquaculture feed or fish oil.

Seabird bycatch loss rate variability in pelagic longline fisheries

Biological Conservation, 2020
Abstract The incidental mortality of seabirds from fisheries ranks as the greatest threat impacting seabirds globally. However, its impact on seabird populations may have been substantially underestimated due to lost, undetected bycatch. To estimate the full extent of the bycatch problem, knowledge about the magnitude and variability of lost bycatch ...

Species’ traits and exposure as a future lens for quantifying seabird bycatch vulnerability in global fisheries

Avian Conservation and Ecology, 2022
Fisheries bycatch, the incidental mortality of non-target species, is a global threat to seabirds and a major driver of their declines worldwide. Identifying the most vulnerable species is core to developing sustainable fisheries management strategies ...

A half century of monitoring reveals contrasting survival responses of Icelandic seabirds to climate and fisheries pressures

Ibis, EarlyView.
Seabirds serve as key indicators of marine environmental changes, with adult survival being a critical parameter for assessing population health. Iceland hosts some of the largest seabird populations in the North Atlantic, making it a valuable location for studying long‐term trends in seabird demographics.

The influence of a cooling water system on waterbird habitat use in a coastal environment

Ibis, EarlyView.
This study investigated the impact of a cooling water system at a nuclear power plant in northern Europe on coastal waterbird habitat use. In winter, the cooling water system provided preferential areas for waterbirds with warm productive waters, and, more importantly, with ice‐free areas.

Estimates of Marine Mammal, Sea Turtle, and Seabird Mortality in the California Drift Gillnet Fishery for Swordfish and Thresher Shark, 1996–2002 [PDF]

, 2004
Estimates of incidental marine mammal, sea turtle, and seabird mortality in the California drift gillnet fishery for broadbill swordfish, Xiphias gladius, and common thresher shark, Alopias vulpinus, are summarized for the 7-year period, 1996 to 2002 ...

Maiden voyage into death: are fisheries affecting seabird juvenile survival during the first days at sea? [PDF]

Royal Society Open Science, 2019
The study of juvenile migration behaviour of seabird species has been limited so far by the inability to track their movements during long time periods. Foraging and flying skills of young individuals are assumed to be inferior to those of adults, making

Shifting Seas, Changing Diets: Evidence of Temporal Dietary Shifts in Marine Megafauna in Southern Brazil (2017–2023)

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.
ABSTRACT Understanding the dietary dynamics of marine megafauna is essential for interpreting ecological interactions and assessing environmental changes in marine ecosystems. We analysed temporal trends in the diets of eight megafaunal species, comprising marine mammals, seabirds, and sea turtles.

Best practices for mitigating seabird bycatch on Taiwanese albacore longline fishing vessels operating in the southeastern Atlantic Ocean

Global Ecology and Conservation
Seabird bycatch—particularly involving albatrosses and petrels—remains a significant conservation concern in pelagic longline fisheries. This study evaluated the effectiveness of three mitigation measures—bird-scaring lines (BSLs), weighted branch lines,

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
