The pirarucu (giant red fish), Arapaima gigas (Cuvier), (Arapaimidae) is among the diverse fish resources of Amazonia which are threatened by over‐exploitation. Little is known about the biology of this species despite its commercial importance. The present paper provides indirect information about the length‐frequency structure of the stock which was estimated by sampling its tongue bone in craft shops and weighing fresh mantas (processed fish product) in fish markets since these were the only remaining recognizable features of the fish. The length‐frequency reconstruction was carried out using a regression analysis calculated by utilizing individuals caught in experimental fishing.
