What is the most abundant fish species in the Indian ocean?
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.
Kurtus indicus
Kurtus indicus, the Indian humphead, is a species of nurseryfish native to fresh, brackish, and marine waters of the coastal regions of southern Asia from India to southeast China and Indonesia. It resembles the closely related "K. gulliveri", but is far smaller, only reaching a length of . Although it has been suggested that the male carries the egg cluster on a hook protruding from the forehead (as known from "K. gulliveri"), available evidence strongly suggests this is not the case in "K. indicus": Out of several thousand examined, none carried eggs in this manner and the male's hook is likely also too small. The female lacks the hook entirely. It is of minor importance to local commercial fisheries.
