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.
Amazon River
The Amazonian fish fauna is the centre of diversity for neotropical fishes. 5,600 species are currently known, and approximately fifty new species are discovered each year. The arapaima, known in Brazil as the "pirarucu", is a South American tropical freshwater fish, one of the largest freshwater fish in the world, with a length of up to . Another Amazonian freshwater fish is the arowana (or "aruanã" in Portuguese), such as the silver arowana ("Osteoglossum bicirrhosum"), which is a predator and very similar to the arapaima, but only reaches a length of . Also present in large numbers is the notorious piranha, an omnivorous fish that congregates in large schools and may attack livestock and even humans. There are approximately 30 to 60 species of piranha. However, only a few of its species are known to attack humans, most notably "Pygocentrus nattereri", the red-bellied piranha. The candirú, native to the Amazon River, is a species of parasitic fresh water catfish in the family Trichomycteridae, just one of more than 1200 species of catfish in the Amazon basin. Other catfish 'walk' overland on their ventral fins, while the kumakuma ("Brachyplatystoma filamentosum"), aka "piraiba" or "goliath catfish", can reach in length and in weight. The electric eel ("Electrophorus electricus") and more than 100 species of electric fishes (Gymnotiformes) inhabit the Amazon basin. River stingrays (Potamotrygonidae) are also known. The bull shark ("Carcharhinus leucas") has been reported up the Amazon River at Iquitos in Peru.
