Pedder galaxias
Pedder galaxias (Galaxias pedderensis) is a critically endangered Australian freshwater fish. It is considered to be extinct in the wild and was originally found only in Lake Pedder in Tasmania.
Range
Originally recorded only in Lake Pedder and inflowing streams, after the construction of the Huon-Serpentine dam in 1972 (the "new" Lake Pedder), its range expanded initially into Lake Gordon and Wedge River. However, by 1980 it had become very rare and no new specimens have been captured in the wild since 1996. Introduced trout are implicated as a major factor in the decline of this species. The species survives in two translocated populations outside its original range, one at Lake Oberon in the Western Arthurs mountain range and one at a modified water supply dam near Strathgordon.
Description
A small greenish-brown fish, off-white to silvery belly, a profuse irregular and highly variable pattern of alternating off-white and brownish contrasting bands extending into the base of the fins and breaking up into fine spots on the lowerr part of the sides. Length to 160 mm.
