Distribution in East Gippsland
Common in rivers and streams In East Gippsland but excluding the

Habitat
Associated with instream cover, rock or wood debris areas providing
shelter from high water velocities. Only infrequently encountered in
open water or above homogeneous substrates without cover.

log or similar location at various depths in water column. Male guards
eggs and attached larvae.
Diet
Other fish, aquatic insects. An ambush predator.
Angling
Often overlooked as an angling option, blackfish provide fine sport
on light tackle. In some areas, blackfish can reach truly prodigious
size, so heavier gear is required at times.
Blackfish are generally caught using bait, scrubworms being the best
option. Some anglers report success fishing with small, dark coloured
lures fished close into creek banks at dusk. Wet flies have also been
used with success.
Remember that blackfish are an ambush predator and are secretive
rather than shy. The trick is to get your bait or lure to within striking
distance of the fish which is generally in heavy cover or lurking under
an undercut bank.
On the table
A superb eating fish with soft white flesh, blackfish need gentle
treatment when cooking for best results. Fillets from larger fish may
be poached of gently fried in a little butter. Do not over cook. Smaller
fish are probably best cooked whole.
