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.
Indian oil sardine
The Indian oil sardine ("Sardinella longiceps") is a species of ray-finned fish in the genus "Sardinella". It is one of the two most important commercial fishes in India (with the mackerel). The Indian oil sardine is one of the more regionally limited species of "Sardinella" and can be found in the northern regions of the Indian Ocean. These fish feed on phytoplankton (diatoms) and zooplankton (copepods).
