We urgently need catch limits for Shortfin Mako and other No Limits? sharks – sign the petition
Common name: Shortfin Mako
Scientific name: Isurus oxyrinchus
IUCN Red List status: Vulnerable
Conservation status: Inadequate and inaccurate recording hampers monitoring of population trends.
General information: Relatively little is known about the biology of the Shortfin Mako. Litters of 4-25 pups have been reported every 2-3 years after a gestation thought to be 15-18 months; life-span is estimated at up to 32 years. Shortfin Mako are also known to undertake seasonal migrations following warmer waters (preferring 17-20°C) although they are largely solitary. Fisheries data is inadequate for this species: most catches are poorly recorded and underestimated with landings data not reflecting numbers finned and discarded at sea. Existing data indicates significant population declines in some regions.
