Advanced telemetry techniques show pelagic longlining is ‘causing decline of blue sharks in UK waters’

Dramatic population declines among species of pelagic shark as a result of overfishing have been reported, with some species now at a fraction of their historical biomass. Advanced telemetry techniques enable tracking of spatial dynamics and behaviour, providing fundamental information on habitat preferences of threatened species to aid conservation.

The paper ‘Spatial Dynamics and Expanded Vertical Niche of Blue Sharks in Oceanographic Fronts Reveal Habitat Targets for Conservation‘ is published in PLoS ONE.

Lead author David Sims of the MBA said “The sharks are having to cross a wall of death across the continental shelf edge off the south west of the UK”
