'White spotted greyling', 1889 Acknowledgements Copyright Reproduced courtesy of the Museum of New Zealand Te Papa Tongarewa Creator F E Clarke, artist, 1889 Identifiers Museum of New Zealand Te Papa Tongarewa number 1992-35-2278/1 TLF resource R4414 Source Museum of New Zealand Te Papa Tongarewa, http://www.tepapa.govt.nz Description This is a watercolour of the New Zealand grayling ('Prototroctes oxyrhynchus') by the flora and fauna artist F E Clarke (1849-99), made in 1889. The fish, also known as upokororo, is long and slim with slivery-blue hues on the underside. Yellow-brown shades on the back, head and tail fin pattern into spots along the back. The words 'White Spotted Greyling. (Nat: Size) (Prototroctes Saleii) Hokitika R. 26th Octr 1889' are written beneath the image. It measures 12 cm x 27 cm. Educational value This asset illustrates the once-abundant New Zealand grayling, which is now extinct - apart from four specimens at the Museum of New Zealand Te Papa Tongarewa, there are fewer than a dozen museum examples in the world. It is the only reliable clue to the fish's colouring - it has been described variously as silvery with slightly brown hues on the back, as a rich red-brown speckled with grey, and as a golden yellow; this lack of exact information is presumably due to the fact that specimens preserved in formalin or alcohol lose their colour. It illustrates a fish about which little is known - it lived in streams and estuaries, where it grazed on algae, grew to 45 cm and weighed up to 1.5 kg; like other native species, the fish probably grew and spawned in fresh water and then, as newly hatched larvae, were washed out to sea to live for several months. It illustrates a species that was a valuable food source for Māori, who caught it in long woven traps called hīnaki. It illustrates a species that became extinct following European settlement - the grayling was widespread in the early years of settlement, and was even used as bulk fertiliser on market gardens, but by the late 1870s numbers were declining, and by 1930 it was considered extinct; the introduction of trout almost certainly contributed to its disappearance, combined with the clearing of vegetation along rivers, resulting in increased light penetration and raised water temperatures. It illustrates a species that is misnamed - it was not related to the European or US grayling, but belonged in a separate family, together with one other Australian species. © Curriculum Corporation and Museum of New Zealand Te Papa Tongarewa, 2006, except where indicated under Acknowledgements Conditions of Use for digital resources from the Te Papa TLF collection Introduction 1.
