Shortfin Mako, Isurus oxyrinchus
Red List status: Vulnerable
Conservation status: The Shortfin Mako is highly vulnerable as its life history is more conservative than other shark species – producing few young and maturing late.
Commercial importance: An important bycatch for pelagic longliners fishing for tuna and swordfish – highly prized for meat.
Management: Require management on an international scale through Regional Fisheries Management Organisations (RFMOs).
Habitat and ecology: Pelagic (open water species) known to undertake seasonal migrations following warmer waters (preferring 17-20°C), although they are largely solitary.
General information: Litters of 4-25 pups have been reported after a gestation of between 15-18 months, they reproduce every 2-3 years and have a life-span of approximately 32 years. Fisheries data is inadequate for this species: most catches are poorly recorded and underestimated.
We urgently need catch limits for:
