Abstract

Although Tasmania posesses a large amount of freshwater
and a considerable variety of freshwater habitats it does
not have a correspondingly large native freshwater fish
fauna. The fauna is low in species number and also lacks
diversity.
Twenty five species are recognised in this work as
native "freshwater" fishes. The term freshwater cannot be
used too rigidly as many other species of fish may spend part
of their life in freshwater ( water with salinity below
3p.p.t. is henceforth used to define freshwater). All of
the fish included in the review with the possible exception
of the whitebait, Lovettia sealii (Johnston) would appear to
require or perhaps prefer freshwater for part or all of
their life. Lovettia sealii has traditionally been included
in works on freshwater fish in Tasmania and it is therefore
included with that group in this work.
Of the 25 species, 18 are of the order Salmoniformes,
suborder Galaxioidei (McDowal3. 1969) and no less than 10
are of the genus Galaxias. The remaining 7 species are
spread through 3 orders as follows: Petromyzoniformes
(2 species), Anguilliformes (2 species) and Perciformes
(3 species).
The fauna shows an amazing radiation in the galaxiid
group but suprisingly little activity elsewhere. In fact
all of the 13 species endemic to the State are galaxioid fishes. However there has been little study of any detail
done in Tasmania on any of the native freshwater fishes.

The only exception to this is the work by Blackburn (1950)
on L. sealii. With the exception of some brief, scattered
details on some species all knowledge of the Tasmanian
native fishes is a result of work done elsewhere in Australia
and New Zealand.
It is beyond the intended scope of this thesis to
include a review of all the taxonomic work on the native
freshwater fish of Tasmania as this would be as voluminous
as the biological data.
The treatment of the taxonomic data will be in the form
of a species list as seen at the present time with a
separate synonomy giving names and first user only for each
species, then a brief coverage of the major taxonomic changes
that have occurred since the original description of each
species.
The literature search relied heavily on the extensive
reference lists in many papers by McDowall ( in particular:
1964a, 1968b, 1970c, 1971a, 1972a, b, 1976c) and in the
papers directly relating to the Tasmanian fauna by Frankenberg
(1974) and Andrews (1976).
