Coryphaena hippurus is harvested throughout its circumglobal range. It can be locally abundant, is fast-growing, early maturing and short-lived. There are some localized declines in catch that may be related to overfishing. However, there is no indication that this species is undergoing significant population declines. It is therefore listed as Least Concern.

Population [top]

Population:From 1961 to 2006, the reported worldwide landings for this species from FAO have gradually increased from 17,000 metric t, to a peak of 59,000 metric t (in 2005). In 2005, Japan reported 10,000 tonnes and Taiwan Province of China approximately 15,000 t.

In the Eastern Pacific, this species can be locally abundant. Data from the Inter-American Tropical Tuna Commission (IATTC 2008) from 1976–2005 widely varies from 200 to 22,000 metric t, with a maximum of 22,000 metric t in 2001. Although there are no data on fishing effort, demand has not decreased. However, there have been many regional fishermen reporting that catches are decreasing, especially in Costa Rica and Ecuador where there are possibly localized declines in catch rates. In Peru, catch of this species is highly fluctuating; there was a catch in 2005–2006 of 2,000 and 4,000 mt by the artisanal fleet, but in 1998 21,000 t were caught after an El Niño event.

There is some evidence of multiple populations based on biological and morphological characteristics (Oxenford and Hunt 1986, Lessa et al. 2008, Duarte-Neto et al. 2008), however there is genetic connectivity between migratory groups in the Atlantic, Caribbean and Gulf of Mexico. The Caribbean Regional Fisheries Mechanism (CRFM 2006) stock assessment recognized the uncertainty about stock structure and conducted separate analyses (one that recognizes separate north and southern stocks and one combining both). The conclusion from all of the assessments was that there was no decline in catch per unit effort (CPUE) indices and therefore the fishery appears sustainable at current levels. They did note the uncertainty and the need for more data from other countries within the stock area.

The Caribbean Regional Fisheries Mechanism (CRFM) 2010 stock assessment analysed data from the Caribbean, Venezuela, Brazil and the U.S. that corroborates that this species migrates from northern Brazil to the eastern Caribbean and may also enter the southeastern Caribbean Sea. The standardized CPUE indices for the eastern Caribbean corroborates that the stock is not declining. In Brazil there is evidence of at least two stocks, one in northern Brazil (shared with the Caribbean) and one in the northeastern Brazilian coast (Lessa et al. 2008). Although there is uncertainty in the data, the stock assessment in the northeast indicated that the stock is fully exploited (Lessa et al. 2009).

This species is widespread and is very common in the Mediterranean, and catches are increasing. The average catch from 2000 to 2009 was about 8,000–10,000 t per year (FAO 2009). Off the coast of Turkey it is seasonally common. FAO landing figures are available from Tunisia, Malta and Spain. Most of the current catch figures are from Tunisia and Spain and are currently increasing. Catches from Malta have remained relatively stable since 1950. The distribution of this species is expanding to the northern part of the western Mediterranean. Catches are much higher in late summer and early autumn.
Current Population Trend:Stable

Habitat and Ecology [top]

Habitat and Ecology:Schools of Coryphaena hippurus can be found in open waters and near coastal areas. This species is found to a depth of 85 m. Its diet consists of smaller fishes, zooplankton, crustaceans, and squid.

This species is fast-growing, and matures relatively early. Maximum size is 200 cm, but more commonly is found to 100 cm.The all-tackle game fish record is of a 39.46 kg fish caught in Papagallo Gulf, Costa Rica in 1976 (IGFA 2011). Longevity can reach four years but is usually less than two years (Oxenford and Hunt 1983, Oxenford 1999, Lessa et al. 2008). Age at first maturity is three to four months in the Gulf of Mexico, four months in the Caribbean (Oxenford 1999), six to seven months in the northeastern North Atlantic, and four months in northeast Brazil (Lessa et al. 2008). Off North Carolina, males reach 50% maturity at 476 mm, 100% at 645 mm; females reach 50% maturity at 458 mm, 100% at 560 mm (Gibbs and Collette 1959, Oxenford 1999, Ditty 2005, Schwenke and Buckel 2008). In the eastern Caribbean, males reach 50% maturity at 91 cm fork length (FL) (four to five months old) and females at 83.5 cm FL (four to five months old) (Oxenford 1999). In Puerto Rico, 50% maturity is reached at 45 cm FL (greater than 7 months old) (Perez and Sadovy 1991).

Spawning is probably year-round at water temperatures greater than 21°C, and spawning occurs in the open water when water temperature rises. In temperate areas such as North Carolina, peak spawning occurs from April through July. In East African waters, spawning season may last from March to early June and spawning occurs inshore. In tropical regions spawning likely occurs year round. Batch spawning occurs at least two or three times per spawning period. Batch fecundity estimates in the west central Atlantic range from 58,000 to 1.5 million eggs and are strongly influenced by size (Gibbs and Collette 1959, Ditty 2005, Schwenke and Buckel 2008, Oxenford 1999). In southern Brazil, spawning occurs from November to February, at least between 20–28°S (Amorim, pers. comm. 2010).
Movement patterns:Full Migrant
Congregatory:Congregatory (and dispersive)

Use and Trade [top]

Use and Trade: A very highly appreciated sportsfish and foodfish, frequently marketed under the Hawaiian name 'Mahi-mahi'. It is marketed frozen and fresh and is of high value.

Threats [top]

Major Threat(s): There are no major threats known to this species. However, it is of high commercial value, with a global catch of 58,076 t in 2005, and is extensively harvested throughout its range (FAO-FIGIS 2005). There have been observed declines in catch in the Eastern Pacific, but this is thought to be a consequence of higher catches during El Niño events.

This species is caught in various types of fishing gear, including longlines, purse seine vessels, and recreational fishing vessels (Palko et al. 1982). It is one of the most important species in artisanal fisheries around the world.

In the Mediterranean, this species is caught in association with fish attracting devices (FADS), trolling line and sport fisheries. These attracting devices such as floating bundles of bamboo reeds or cork planks are used to concentrate Dolphinfish before nets are set. The use of FADS are increasing the bycatch of this species (Nelson pers. comm. 2010). Small quantities are taken as bycatch in longline and driftnet fisheries.

The Caribbean Regional Fisheries Mechanism (CRFM) recognizes that the lack of any institutional framework or regional body for collaborative or shared management of this resource is a concern given the increasing catches of this species in the region (CRFM 2006).

Conservation Actions [top]

Conservation Actions: It is considered a highly migratory species under Annex I of the 1982 Convention on the Law of the Sea.

In Ecuador, there is a minimum catch size of 70 or 80 cm. In Mexico, there are area-closures for commercial fishing for this species, and a two fish sport limit. In the past, there have been conservation measures implemented by the Inter-American Tropical Tuna Commission (IATTC) for no purse-seine fishing. In Ecuador, 50% of the fishing fleet, including those for tunas, use an experimental sorting grid to release juveniles, small tunas and other bycatch species. In 2005, a recreational fishing limit of five fish per fishermen per fishing day was established for this species in Puerto Rico (Rodrigues-Ferrer et al. 2006).

In the U.S., there are bag limits and size limits in the recreational fishery and size and trip limits in the commercial fishery (SAFMC 2003).

This species' distribution overlaps with a number of marine protected areas.
