Shark discards in selective and mixed-species pelagic longline fisheries
PLOS ONE, 2020 The conservation status of several pelagic shark species is considered vulnerable with declining populations, yet data on shark fishing mortality remain limited for large ocean regions. Pelagic sharks are increasingly retained by mixed-species fisheries, or are discarded and not reported by selective fisheries for tunas (Thunnus spp.) or swordfish ...

Conservation Biology, EarlyView.Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.

Selection And Mortality In Pelagic Longline Fisheries For Haddock
, 1997 No abstracts are to be cited without prior reference to the author.The bycatch of haddock (Melanogrammus aeglefinus) below legal size in the pelagic longline fisheries for haddock off the coast of Finnmark, northern Norway, is often high. This project was aimed at reducing the bycatch of undersized haddock through alterations in gear technology and ...

Survey- and fishery-derived estimates of Pacific cod (Gadus macrocephalus) biomass: implications for strategies to reduce interactions between groundfish fisheries and Steller sea lions (Eumetopias jubatus) [PDF]
, 2005 Survey- and fishery-derived biomass estimates have indicated that the harvest indices for Pacific cod (Gadus macrocephalus) within a portion of Steller sea lion (Eumetopias jubatus) critical habitat in February and March 2001 were five to 16 times ...

Interannual Differences for Sea Turtles Bycatch in Spanish Longliners from Western Mediterranean Sea
The Scientific World Journal, 2014 Recent studies showed that regional abundance of loggerhead and leatherback turtles could oscillate interannually according to oceanographic and climatic conditions. The Western Mediterranean is an important fishing area for the Spanish drifting longline

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework
Conservation Biology, EarlyView.Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.
