Maldive fish
The abundant sea harvest of the Indian Ocean around the Atolls of the Maldives and, Lakshadweep in India yields many pelagic fishes, like skipjack, yellowfin tuna, little tunny (known locally as laṭṭi) and frigate mackerel. All these fishes have been traditionally processed on the Maldive Islands as a main source of food as well as income for Maldivians.
Leiognathus longispinis
Leiognathus longispinis, commonly known as the longspine- or Smithurst's ponyfish, is a fish of brackish and marine waters found in the Indian and western Pacific Oceans, from India through Malaysia and Indonesia south to northern Australia and east to the Philippines and Fiji It was described in 1835 by French Zoologist Achille Valenciennes from a specimen caught off Waigeo island in Irian Jaya in New Guinea. In 1886 Ramsay and Ogilby described what turned out to the same species from Hood Lagoon in Papua New Guinea, naming it "Leiognathus smithursti". In 2008, ichthyologists Prosanta Chakrabarty and John S. Sparks resurrected the genus "Aurigequula" and placed "L. longispinis" and "L. fasciatus" in it, on the basis of a horizontal row of yellow markings on their flanks and elongated second spine of the dorsal fin. However, a molecular study showed that the genus "Leiognathus" was nested within "Aurigequula", and hence the genera were merged once more. It is unclear whether the longspine ponyfish as currently defined represents a single or more than one species.
