Blue shark have low resilience to fishing and no reference points are defined for this stock. The species is data limited but current assessments indicate no concern for fishing pressure. Recent declines in catch rates alongside a lack of historic baselines for the species mean there are concerns for biomass. Blue sharks are poorly managed across the north Atlantic due to a lack of reliable data. Management requires considerable improvement to ensure stock assessments are accurate and up to date. Blue sharks in the Atlantic are mainly landed as bycatch in longline fisheries for tuna and swordfish. While longlining is unlikely to have habitat impacts, it can have a bycatch of highly vulnerable species such as other sharks, turtles, and seabirds. Although discards of caught blue shark are high many are also landed as both the fins and meat are valued and found in UK and global markets.Rating last updated December 2021.For more information about this fishery in Cornwall, see:https://www.cornwallgoodseafoodguide.org.uk/fish-guide/blue-shark.php
