"Alectis" is a
genusof fishin the family Carangidaecontaining three extant species, all of which are large marine fishes. They are commonly known as threadfish, diamond trevallies and occasionally pompanos, although they have no close affiliation with the true pompanogenus.
"Alectis" is one of 33 genera in the jack and horse mackerel family
Carangidae. The Carangidae are perciformfishes in the suborder Percoidei. [ITIS | ID = 168600 | taxon = Alectis | year = 2007 | date = 21 October]
The first fish in the genus to be described was "
Alectis ciliaris" under the genus name of "Zeus", part of the doryfamily. Lacépède recognized the species was not a dory and assigned it to a new genus, "Gallus", however this was preoccupied by a bird. cite book | last = Hosese | first = D.F. | coauthors = Bray, D.J., Paxton, J.R. and Alen, G.R. | title = Zoological Catalogue of Australia Vol. 35 (2) Fishes | publisher = CSIRO | date = 2007 | location = Sydney | pages = 1150 | isbn =978-0-643-09334-8 ] In 1815, Rafinesque proposed the name "Alectis", into which three species were eventually placed. Georges Cuvierproposed a second name, "Scyris" for the genus in 1829, but "Alectis" had priority and has therefore been cemented for the time being.cite book | last = Carpenter | first = Kent E. | coauthors = Volker H.

A single species has been identified the
fossil record; "Alectis simus", from the Eoceneperiod of England. It was found alongside a number of extinct and extant carangid genera including "Caranx" and "Usacaranx" (extinct).

The fish of the genus are large, powerful fishes that look very similar to a number of other large
jacks, with the main difference being the profile of the head and the characteristic long filamentous anal and dorsal finsdisplayed by juveniles of these species. They are generally a silver colour, with pale green to hyalinefins. "A. indica" is the largest of the genus, growing to a reported 165 m and 25 kg in weight.cite journal | last = Gunn | first = John S. | title = A revision of selected genera of the family Carangidae (Pisces) from Australian waters | journal = Records of the Australian Museum | volume = Supplement 12 | pages =1–78 | date = 1990 | accessdate = ]
The genus has a circum-tropical distribution, with adults generally restricted to
reefs in coastalareas down to 100 m, while juveniles are often pelagic.cite book | last = Carpenter | first = Kent E. | coauthors = Volker H.

A little is known of their reproductive habits and larval phases, with spawning occurring during daylightbetween pairs. [cite journal | last = Westernhagen | first = H.

Relationship to humans
The genus is of minor importance to both commercial and
subsistencefisheries, with the species generally not numerous enough to warrant a specific fishery. All species are considered fine game fish, attaining large sizes and capable of blistering runs. The flesh of the genus is generally considered very good for culinarypurposes, although at least one species has been implicated in a case of Ciguaterapoisoning. [cite journal | last = Bourdeau | first = P. | coauthors = Bagnis, R. | title = Risk factors of ciguatera in the French West Indies in Saint-Barthelemy, Saint-Martin and Anguilla (Article in French) | journal = Revue d'élevage et de médecine vétérinaire des pays tropicaux | volume = 42 | issue = 3 | pages = 393–410 | publisher = | location = | date = 1989 | id = ISSN 1951-6711 | accessdate = ] In Singapore, "A. indica" has successfully been bred in aquaculturefor food production in relatively low numbers. Juveniles are occasionally used in saltwater aquariums, noted for their filamentous anal and dorsal fins.
