Marron
- Cherax cainii Austin, C.M. in Austin, C.M & Ryan, S.G. 2002. Allozyme evidence for a new species of freshwater crayfish of the genus Cherax Erichson (Decapoda: Parastacidae) fron the south-west of Western Australia. Invertebrate Systematics 16: 357-367 [360-363].
Type data:
Holotype WAM C28348 ♂, Scott River, Brennan bridge, Scott River Road, 12 km north-east of Augusta, south-western Western Australia.
Introduction
This species was originally confused with Cherax tenuimanus, however this taxon was split into two by Austin & Ryan (2002). Cherax tenuimanus is restricted to the Margaret River. The common 'Marron', which has formed the basis of both a wildcaught fishery and an aquaculture industry, is based on Cherax cainii and not C. tenuimanus as long understood. An application to the ICZN to erect neotypes for both species so as to maintain the name Cherax tenuimanus for the common widespread species was rejected (ICZN 2008).
Distribution
States
South Australia, Victoria, Western Australia
Extra Distribution Information
Originally endemic to south-west of Western Australia, but Cherax cainii has been transplanted to natural and artificial water bodies and as a result has become widespread throughout the south-west of Western Australia. It has also been introduced into Victoria and South Australian freshwater habitats where feral populations have become established (Austin, 2002: 360). Also widely cultured in QLD until the late 1980s but since then most farmers have switched to Redclaw.
