It is also widely called dorado (not to be confused with ''Salminus brasiliensis'', a freshwater fish) and dolphin (not to be confused with the aquatic mammal dolphin). It is one of two members of the family Coryphaenidae, the other being the pompano dolphinfish. These fish are most commonly found in the waters around the Gulf of Mexico, Costa Rica, Hawaii, and the Indian Ocean. In Italy it is called corifena, lampuga or pesce capone, and has even given its name to the caponata though eggplant has now taken the place of the fish.

== Nomenclature ==

The name ''mahi-mahi'' comes from the Hawaiian language<ref>{{Hawaiian Dictionaries|dolphin|q=dolphin}}</ref> and means 'very strong', through the process of reduplication.<ref>{{Cite web |title=mahimahi |url=https://maoridictionary.co.nz/word/3352 |access-date=2 September 2022 |publisher=Te Aka Māori Dictionary |language=en}}</ref> Though the species is also referred to as the common dolphinfish, they are not related to dolphins; the origin of the name "dolphinfish" is recent and was given to avoid confusion with dolphins, as the traditional name of the fish was also "dolphin". See ''Coryphaena'' for the possible etymologies of ''dolphinfish''. In parts of the Pacific and along the English-speaking coast of South Africa, the mahi-mahi is commonly referred to by its name in Spanish, {{Lang|es|dorado}}.<ref>{{Cite news|url=http://wwfsassi.co.za/fish-detail/38/|title=Fish detail|work=WWF SASSI|access-date=31 May 2018|language=en-US|archive-date=10 June 2018|archive-url=https://web.archive.org/web/20180610154939/http://wwfsassi.co.za/fish-detail/38/}}</ref>

Linnaeus named the genus, derived from the Greek word, {{Lang|grc|{{Script|Greek|κορυφή}}}}, {{Lang|grc-latn|koryphe}}, meaning 'top' or 'apex', in 1758. Synonyms for the species include ''Coryphaena argyrurus'', ''Coryphaena chrysurus'', and ''Coryphaena dolfyn''.<ref name=Fishbase/>

Mature males have distinctive "foreheads"; it grows as the fish matures and often protrudes well above the body proper, which is streamlined by the musculature of the back. This "hump" is a sexually dimorphic feature; females have a rounded head. Their caudal fins and anal fins are sharply concave. They are distinguished by dazzling colors – golden on the sides, and bright blues and greens on the sides and back. The pectoral fins of the mahi-mahi are iridescent blue. The flank is broad and golden.<ref>{{cite web|author=Dianne J. Bray|year= 2011|title= Mahi Mahi, ''Coryphaena hippurus''|website=Fishes of Australia|access-date=7 October 2014|url=https://fishesofaustralia.net.au/home/species/1730}}</ref> Out of the water, the fish often change color (giving rise to their Spanish name, ''{{Lang|es|dorado}}'', 'golden'), going through several hues before finally fading to a muted yellow-grey upon death.

== Biology == Mahi-mahi can live for up to five years, although they seldom exceed four. Females are usually smaller than males. Catches typically are {{cvt|7|to|13|kg|lb}} and a meter (3 ft) in length. They rarely exceed {{cvt|15|kg|lb}}, and mahi-mahi over {{cvt|18|kg|lb}} are exceptional. Mahi-mahi are among the fastest-growing of fish. They spawn in warm ocean currents throughout much of the year, and their young are commonly found in rafts of ''Sargassum'' weeds. Young mahi-mahi migrate past Malta where they are called {{Lang|mt|lampuki}} and Sicily where they are known as {{Lang|scn|lampuga}} or {{Lang|scn|capone}}; there they are fished using nets and floating mats of palm leaves under which they collect.{{Citation needed|date=November 2025}}

== Reproduction == Males and females are sexually mature in their first year, usually by the age of 4–5 months. Spawning can occur at body lengths of {{cvt|20|cm|in}}. Females may spawn two to three times per year, and produce between 80,000 and 1,000,000 eggs per event. In waters at {{cvt|28|°C|°F}}, mahi-mahi larvae are found year-round, with greater numbers detected in spring and fall.<ref name="ADW">{{cite web |url= http://animaldiversity.ummz.umich.edu/site/accounts/information/Coryphaena_hippurus.html |title=''Coryphaena hippurus'' |first=Joshua |last=Bostwick |year=2000 |work=Animal Diversity Web |access-date=17 August 2011}}</ref> Mahi-mahi fish are mostly found in the surface water. Their flesh is grey-white when raw, cooking to an attractive white with a clean, non-fishy flavour.{{Citation needed|date=November 2025}}

== Diet == Mahi-mahi are carnivorous, feeding on flying fish, crabs, squid, mackerel, and other forage fish. They have also been known to eat zooplankton. To pursue such varied pelagic prey, mahi-mahi are fast swimmers, swimming as fast as {{convert|50|kn|km/h mph|1}}.{{citation needed|date=November 2023}}

{{Clear}} == Relation to humans == [[File:Fresco of a fisherman, Akrotiri, Greece.jpg|thumb|upright|Young fisherman with dolphinfish from Santorini, Greece, c. 1600 BCE (Minoan civilization)]] === Fishing === {{Main|Mahi-mahi fishing}} ==== Recreational fishing ==== Mahi-mahi are highly sought for sport fishing and commercial purposes. Sport fishermen seek them due to their beauty, size, food quality, and healthy population. Mahi-mahi can be found in the Caribbean Sea, on the west coast of North and South America, the Pacific coast of Costa Rica, the Gulf of Mexico, the Atlantic coast of Florida and West Africa, Indian Ocean, Bay of Bengal, South China Sea and Southeast Asia, Hawaii, Tahiti, and many other places worldwide.<ref>{{Cite WoRMS|author=Bailly, Nicolas|year=2008|title= ''Coryphaena hippurus'' Linnaeus, 1758 |id=126846 |access-date=29 January 2025 |language=en}}</ref><ref>{{Cite web |title=What Is Mahi Mahi? |url=https://www.foodnetwork.com/how-to/packages/food-network-essentials/what-is-mahi-mahi |access-date=29 January 2025 |website=Food Network |language=en}}</ref><ref name=ADW/>

Fishing charters most often look for floating debris and frigatebirds near the edge of the reef in about {{convert|120|ft|m}} of water. Mahi-mahi (and many other fish) often swim near debris such as floating wood, five-gallon bucket lids, palm trees and fronds, or sargasso weed lines and around fish buoys. Frigatebirds search for food accompanying the debris or sargasso. Experienced fishing guides can tell what species are likely around the debris by the birds' behavior.

{{convert|30|to|50|lb|adj=on}} gear is more than adequate when trolling for mahi-mahi. Fly-casters may especially seek frigatebirds to find big mahi-mahis, and then use a bait-and-switch technique. Ballyhoo or a net full of live sardines tossed into the water can excite the mahi-mahis into a feeding frenzy. Hookless teaser lures can have the same effect. After tossing the teasers or live chum, fishermen throw the fly to the feeding mahi-mahi. Once on a line, mahi-mahi are fast, flashy, and acrobatic, with beautiful blue, yellow, green, and even red dots of color.<ref>{{Cite web |title=Everything You Need to Know About Mahi-Mahi |url=https://www.thespruceeats.com/all-about-mahi-mahi-fish-1300648 |access-date=29 January 2025 |website=The Spruce Eats |language=en}}</ref><gallery heights="140" mode="packed"> File:IMAG0302.jpg|Mahi-mahi in a fish market File:IMAG0303.jpg|Closeup File:Common Dolphinfish, Bali Sea, Bali, ID imported from iNaturalist photo 540579538 (cropped).jpg|Young mahi-mahi, in Indonesia </gallery>

==== Commercial fishing ==== [[File:Common dolphinfish, capture production, thousand tonnes, 1950-2022.svg|thumb|Global capture production of Common dolphinfish (''Coryphaena hippurus'') in thousand tonnes from 1950 to 2022, as reported by the FAO<ref>{{Cite web |title=Fisheries and Aquaculture - Global Production |url=https://www.fao.org/fishery/en/collection/global_production?lang=en |access-date=6 May 2024 |website=Food and Agriculture Organization of the United Nations (FAO)}}</ref>]] The United States and the Caribbean countries are the primary consumers of this fish, but many European countries are increasing their consumption every year.{{citation needed|date=May 2010}} It is a popular food fish in Australia, usually caught and sold as a byproduct by tuna and swordfish commercial fishing operators. Japan and Hawaii are significant consumers. The Arabian Sea, particularly the coast of Oman, also has mahi-mahi. At first, mahi-mahi were mostly bycatch in the tuna and swordfish longline fishery. Now, they are sought by commercial fishermen on their own merits.

In French Polynesia, fishermen use harpoons, using a specifically designed boat, the {{Lang|ty|poti marara}}, to pursue it, because mahi-mahi do not dive. The ''{{Lang|ty|poti marara}}'' is a powerful motorized V-shaped boat, optimized for high agility and speed, and driven with a stick so the pilot can hold his harpoon with his right hand. The method is also practiced by fishermen in the Philippines, especially in the northern province of Batanes, where the harpooning is called {{Lang|fil|pagmamamataw}}.

===In astronomy=== thumb|Dorado's position in the sky The constellation Dorado, created in 1598, is named for the mahi-mahi. It is located near the Large Magellanic Cloud.<ref>{{cite web|url=http://www.ianridpath.com/startales/dorado.html|title=Dorado|last=Ridpath|first=Ian|website=Star Tales|access-date=December 27, 2022}}</ref>

=== Environmental and food safety concerns === Depending on how it is caught, mahi-mahi is classed differently by various sustainability rating systems:

* The Monterey Bay Aquarium classifies mahi-mahi, when caught in the US Atlantic, as a best choice, the top of its three environmental-impact categories. The aquarium advises to avoid imported mahi-mahi harvested by long line, but rates troll and pole-and-line caught as a good alternative. * The Natural Resources Defense Council classifies mahi-mahi as a "moderate mercury" fish (its second-lowest of four categories), and suggests eating six servings or fewer per month.<ref>{{cite web | url = http://www.nrdc.org/health/effects/mercury/guide.asp | title = Consumer Guide to Mercury in Fish | date = 10 March 2016 }}</ref>

The mahi-mahi is also a common vector for ciguatera poisoning.<ref>{{cite web | url = http://research.myfwc.com/features/view_article.asp?id=1187 | title = Ciguatera Fish Poisoning (CFP) | publisher = Fish and Wildlife Research Institute | access-date = 4 January 2010 | archive-url = https://web.archive.org/web/20061125233242/http://research.myfwc.com/features/view_article.asp?id=1187 | archive-date = 25 November 2006 }}</ref> Although a very popular food dish in many parts of the world, there have been reports of ciguatera poisoning from human consumption of this fish. Ciguatera poisoning is caused by the accumulation of toxins (ciguatoxins and maitotoxin) in the flesh of the fish over time. These are produced by ''Gambierdiscus toxicus'' which grows together with marine algae, which causes fish like the mahi-mahi to consume them by accident.<ref name=Florida>{{cite web |url=https://www.floridamuseum.ufl.edu/discover-fish/species-profiles/coryphaena-hippurus/|title=''Dolphinfish''|year=2019 |publisher=Florida Museum of Natural History |access-date=2 June 2019}}</ref>

Mahi-mahi naturally have high levels of histidine, which is converted to histamine when bacterial growth occurs during improper storage or processing.<ref name=Yellow2018>{{cite web |title=Food Poisoning from Marine Toxins - Chapter 2 - 2018 Yellow Book |url=https://wwwnc.cdc.gov/travel/yellowbook/2018/the-pre-travel-consultation/food-poisoning-from-marine-toxins |website=CDC |access-date=1 June 2018 |language=en-us |date=2017}}{{PD-notice}}</ref> Subsequent cooking, smoking, or freezing does not eliminate the histamine. This leads to a foodborne illness known as scombroid food poisoning, which also affect other fish such as tuna, mackerel, sardine, anchovy, herring, bluefish, amberjack and marlin.<ref name=Yellow2018/> Symptoms are those of histamine intolerance and may include flushed skin, headache, itchiness, blurred vision, abdominal cramps, and diarrhea,<ref name=Yellow2018/> and the onset of symptoms is typically 10 to 60 minutes after eating and can last for up to two days.<ref name=Yellow2018/> Rarely, breathing problems (like that of allergic asthma) or an irregular heartbeat may occur.<ref name=Yellow2018/> Diagnosis is typically based on the symptoms and may be supported by a normal blood tryptase.<ref name=Rid2016>{{cite journal |last1=Ridolo |first1=E |last2=Martignago |first2=I |last3=Senna |first3=G |last4=Ricci |first4=G |title=Scombroid syndrome: it seems to be fish allergy but... it isn't. |journal=Current Opinion in Allergy and Clinical Immunology |date=October 2016 |volume=16 |issue=5 |pages=516–21 |doi=10.1097/ACI.0000000000000297 |pmid=27466827|s2cid=21610715 }}</ref>
