Rating*****
Shark, mako
Isurus oxyrinchus
REASON TO AVOID
The low reproductive capacity of the shortfin mako makes it very susceptible to depletion by fishing. In the Atlantic the shortfin mako shark stock has declined and is possibly depleted in the North Atlantic. Shortfin mako shark is assessed as Vulnerable globally but is classified as Critically Endangered in the Mediterranean Sea and Near Threatened in the North-east Pacific by the IUCN - the World Conservation Union. Avoid eating this and other shark species.
