Mahimahi, which means “very strong” in Hawai’ian, is a highly migratory pelagic species found in the world’s all tropical and subtropical waters including the Atlantic, Indian and Pacific Oceans. It is also known as Dolphinfish, but has no relation to dolphins, a marine mammal. Mahimahi are brightly colored– the back is an electric greenish blue, the lower body is gold or sparkling silver, and the sides have a mixture of dark and light spots. Their bright pattern fades almost immediately after they’re harvested. Adult males have a square head shape but females have a more rounded head. Mahimahi can be distinguished from the pompano dolphin by its 55 to 66 dorsal fin rays and a very wide, square tooth patch on the tongue. Dorado is a very productive fish. They’re able to reproduce early in life, at 4 to 5 months old, and scientists believe mahimahi spawn every 2 to 3 days throughout their entire spawning season, perhaps even year-round. Females release between 33,000 and 66,000 eggs each time they spawn. In the Atlantic, they spawn under patches of Sargassum. Mahimahi are top predators and only have a few predators themselves. They feed in surface water during the day and eat a wide variety of species, including small pelagic fish, juvenile tuna, billfish, jacks, pompano, and pelagic larvae of nearshore, bottom-living species. They also eat invertebrates such as cephalopods (octopus, squid, etc.), mysids (small, shrimp-like creatures), and jellyfish. Large tuna, rough-toothed dolphin, marlin, sailfish, and swordfish feed on mahimahi, particularly juveniles. Dorsal spines (total): 0; Dorsal soft rays (total): 58-66; Anal spines: 0; Anal soft rays: 25 - 31; Vertebrae: 31. Greatest body depth in adults less than 25% of standard length; tooth patch on tongue small and oval; single dorsal fin extending from above eye almost to caudal fin with 58-66 rays; a concave anal fin extending from anus almost to caudal fin; pectoral fin more than half of head length. Caudal vertebrae usually 18 (Ref. 10998). Mature males posses a prominent bony crest in front of the head. The color is striking with golden hues on the sides, metallic blues and greens on the back and sides, with white and yellow on the underparts. Small specimens have pronounced vertical bars on the sides of the body.
