The New Zealand grayling (Prototroctes oxyrhynchus) is an extinct species of fish that was endemic to New Zealand. It was known to the Māori by many names, including pokororo, paneroro, kanae-kura, and most commonly, upokororo. The variety of names for the fish came from either multiple iwi, or to describe the fish at different periods of its life cycle. Even though this fish is named grayling, it is not related to European or American graylings and lacks the large dorsal fin ‘typical’ graylings are characterised by. It is, however, closely related to the Australian grayling (P. maraena).[3][4] The New Zealand grayling was an amphidromous species, migrating between freshwater and saltwater during different seasons as well as stages in their life cycle.[5] The last sighting of the New Zealand grayling was in 1923, and it was declared extinct in 2018.
