Distribution and ecology of the canterbury mudfish, neochanna burrowsius (phillipps) (salmoniformes: Galaxiidae)

Abstract

The present distribution of the rare Canterbury mudfish is described. It is found mainly in man-made or man-modified habitats and is capable of aestivation. It feeds mainly on aquatic insect larvae and crustaceans and is also cannibalistic, eating its own eggs. Spawning occurs in late winter and early spring and appears to be stimuhted by rainfall. The juvenile stage is figured and described, and its pattern of activity compared with that of the adult. The setting up of reserves or the prevention of land modification in muclfish habitats is suggested to ensure the (Con tinuecl survival of the species. © 1975 Taylor & Francis Group, LLC.
