Atlantic Shortfin Mako Shark

Mako shark

About The Species

U.S. wild-caught Atlantic shortfin mako shark is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations.

Population Level

Above target population level.

Fishing Status

At recommended level.

Habitat Impact

Gear used to harvest Atlantic shortfin mako does not contact the ocean floor and has no impact on habitat.


Regulations are in place to minimize bycatch.


  • Shortfin mako sharks have very pointed snouts and long gill slits. 
  • They have dark blue/gray backs, light metallic blue sides, and white undersides.
  • Shortfin mako sharks are easily confused with longfin makos. Longfin makos have much longer pectoral fins and larger eyes, and the area on their snout is darker. 
Behavior and Diet
  • Shortfin mako sharks grow slowly and can reach up to 12 feet long and can live to be 11 ½ years old.
  • They are not able to reproduce until about 4 to 6 years old. They have a 2-year reproductive cycle and a gestation period of approximately 12 months.
  • Mating occurs from late winter to mid-spring. Eggs are fertilized internally and develop inside the mother. 
  • Females bear live pups, which are fairly large when born. This large size at birth helps reduce the number of potential predators and enhances the pups’ chance of survival. 
  • Litters have between 12 and 20 pups, though scientists have only examined a handful of litters.
  • Shortfin mako sharks are aggressive predators that feed near the top of the food web on marine fishes such as bluefish, swordfish, tuna, and other sharks.   
  • They have few predators, mainly larger sharks that may prey on smaller shortfin mako sharks.
Location Description

Off the East Coast, Atlantic shortfin mako sharks are found from New England to Florida and in the Gulf of Mexico.
They are highly migratory and can travel over entire oceans.

  • NOAA Fisheries and the Atlantic Highly Migratory Species Division manage the Atlantic shortfin mako fishery in the United States.  
  • Managed under the Consolidated Atlantic Highly Migratory Species Fishery Management Plan:
    • Permits are required, and only a limited number of permits are available.
    • Commercial quotas and limits on how many sharks can be landed per fishing trip.
    • Gear restrictions and requirements.
    • Fishing season is generally year-round, but individual commercial shark fisheries close when the quota is reached.
    • Shark dealers are required to attend Atlantic shark identification workshops to help them better identify shark species.
    • Prohibited species—there are more than 20 species of sharks that cannot be landed (e.g., white, dusky, basking, longfin mako, night). Some of these species look similar to the species that can be landed.
    • The Shark Conservation Act requires that all sharks, with one exception, be brought to shore with their fins naturally attached.
    • Compliance guides are available for all commercial and recreational regulations across Atlantic highly migratory species fisheries.
  • Highly migratory species, such as mako sharks, have complicated management that requires international cooperation.
