Dolphin Fish

Coryphaena hippurus

AKA:

Mahi-Mahi, Dorado

Managed by:

SAFMC, GMFMC


Physical description:

The dolphin fish has bright turquiose, green and yellow patterns, which fade almost immediately upon death. This species may be distinguished from the pompano dolphin by its 55-66 dorsal fin rays, and a very wide and square tooth patch on the tongue. The body tapers sharply from head to tail; irregular blue or golden blotches scattered over sides; anterior profile of head on adult males is nearly vertical; head of females more sloping; the single dark dorsal fin extends from just behind the head to the tail; anal fin margin concave and extending to tail.


Biological description:

Dolphin are fast growing, prolific and have a short life span - an average of 5 years. Average fork lengths for males and females ranges from 34 to 55 inches. Males grow faster and usually live longer than females. The spawning season varies with latitiude. Dolphin collected in the Florida Current spawned from November through July, and those collected from the Gulf Stream near North Carolina were reproductively active during June and July. Small females may spawn 240 thousand pelagic eggs, and fish larger than 43 inches may spawn several million. Dolphin are attracted to Sargassum, a floating brown algae, which serves as a hiding place and source of food. Other sources of food associated with the Sargassum include small fish, crabs, and shrimp. Dolphin reach swimming speeds estimated at 50 knots and may also pursue fast -swimming fish, such as flying fish or mackerels. Often man made garbage is entangled in the floating Sargassum, and is consumed by dolphin. Plastic wrappers, small light bulbs, rope and string have all been removed from the stomachs of dolphin.

Additional Updates:

Regulation Update - Effective January 27, 2016: New federal regulations will allow recreational fishermen to bring fillets of dolphin and wahoo from The Bahamas into the U.S. federal waters and update regulations that currently allow recreational fishermen to bring snapper-grouper fillets from The Bahamas into the U.S. federal waters. 

  • Two fillets are equivalent to one fish for dolphin, wahoo, and snapper-grouper species brought into the U.S. federal waters
    from The Bahamas.
  • Require fishers to retain skin on the entire fillet of dolphin, wahoo, and snapper grouper species.
  • Require fishing gear to be stowed while transiting the U.S. federal waters from The Bahamas. A vessel carrying fillets of dolphin, wahoo, or snapper-grouper species lawfully harvested in Bahamian waters would not be allowed to stop in the U.S. federal waters during the transit.
  • Require stamped and dated passports, as well as valid current Bahamian cruising and fishing permits to prove that the recreational fishers were in The Bahamas.
  • Not allow recreationally caught dolphin, wahoo, or snapper-grouper from The Bahamas to be sold or purchased in the U.S.
  • Not exempt recreational fishermen from any other Federal fishing regulations such as fishing seasons, recreational bag limits, size limits, and prohibited species.
