Mahi-mahi fishing
Mahi-mahi are swift and acrobatic game fish with striking colours. Their sides are golden with iridescent greens and blues, and their belly is white and yellow. These colours can change rapidly, excited fish "light up", and dying mahi-mahi often turn silvery over-all with blue spots on the flanks. These colours darken when the fish dies (see illustrations)〔 The current IGFA all tackle record is 39.91 kilograms (88lb), caught in 1998 in Exuma, Bahamas by Chris Johnson of Lake Mary, Florida.〔(''2009 World Record Game Fishes'' ) International Game Fish Association (IGFA).〕 Catches average , and any mahi-mahi over is exceptional. Males are often larger than females.
Mahi mahi are also known as dorado or dolphin fish. However, they are not at all related to dolphins. Dolphins are air-breathing mammals, where as mahi mahi are water-breathing fish, distantly related to perch. They are good eating fish, similar to flounder and other whitefish.
==Description==
Mahi-mahi are a blue-water, open ocean, highly migratory schooling fish found around the world in tropical and subtropical waters at depths up to , but more typically near . They feed on forage fish, such as mackerel and squid, and also zooplankton and crustaceans.〔〔FAO Fisheries Department (1994) (''World review of highly migratory species and straddling stocks'' ) FAO Fisheries. Technical Paper No. 337. Rome.〕 They are particularly adapted to hunting flying fish.〔FAO: Lesser Antilles Pelagic Ecosystem (LAPE) project: (''Ecosim - Scenario simulations'' ) FAO Fisheries and Aquaculture, Rome. Updated 28 November 2008.〕
They spawn in warm ocean currents throughout much of the year, and their young are often found among seaweed. They are a relatively short lived species, with a life span of only four or five years. Mahi-mahi are among the fastest growing fish, with a minimum population doubling time under 15 months. This makes them resilient to fishing pressure. However, their current vulnerability is moderate to high.〔Cheung, W.W.L., T.J. Pitcher and D. Pauly (2005) (''A fuzzy logic expert system to estimate intrinsic extinction vulnerabilities of marine fishes to fishing'' ) Biol. Conserv. 124:97-111.〕
