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.
Western Ghats
There is a higher fish richness in the southern part of the Western Ghats than in the northern, and the highest is in the Chalakudy River, which alone holds 98 species. Other rivers with high species numbers include the Periyar, Bharatapuzha, Pamba and Chaliyar, as well as upstream tributaries of the Kaveri, Pambar, Bhavani and Krishna rivers. The most species rich families are the Cyprinids (72 species), hillstream loaches (34 species; including stone loaches, now regarded a separate family), Bagrid catfishes (19 species) and Sisorid catfishes (12 species). The region is home to several brilliantly colored ornamental fishes like Denison's (or red line torpedo) barb, several species of "Dawkinsia" barbs, zebra loach, "Horabagrus" catfish, dwarf pufferfish and dwarf Malabar pufferfish. The rivers are also home to "Osteobrama bakeri", and larger species such as the Malabar snakehead and Malabar mahseer. A few are adapted to an underground life, including some "Monopterus" swampeels, and the catfish "Horaglanis" and "Kryptoglanis".
