Abstract

Both brown (Salmo trutta L.) and rainbow (S. gairdnerii trout Richardson) have been introduced into inland waters of the south-west of Western Australia to provide an amateur sport fishery on a gamefish. The large indigenous marron (Cherax tenuimanus Smith) is present in most of these waters. The only large native fish present is the cobbler (Tand- anus bostocki Whitley) which, while highly edible like the marron, has no game-fish qualities.

Hatchery production of trout for stocking waters has been centred at Pemberton in the lower south-west since 1931 when Mr. Cyril Glew, acting in a private capacity, succeeded in hatching imported ova and releasing fry in the Warren District (See Annual Reports of the Pemberton "Warren Trout Acclimatization Society, 1943-1961, for accounts of activities of historical interest).

Despite the prolonged stocking activities lasting more than 36 years, when the present appraisal was commenced, in 1967, there was no clear information on whether trout acclimatization could be judged a success or failure. In fact informed opinion varied from the conclusion that the waters provided insufficient food for a successful trout fishery (Jenkins 1951-53) to the view that fishing comparable with the best in the eastern states was available (Francois, 1966).
