 Tasmanian Inland Fishery Species
Brown trout
Brown trout have established self sustaining populations in most of the State's rivers, lakes and estuaries.  It is the wild brown trout fishery upon which Tasmania's angling reputation has been built.  Brown trout are fished for with equal success by bait fishing, lure casting, trolling and fly-fishing and are renowned as a fish that test the skills of all anglers.

Rainbow trout (Oncorhynchus mykiss)
Rainbow trout, while not as common as brown trout, can also be found in many lakes and some rivers, and provide the basis for farm dams and other stocked fisheries. Rainbow trout are often voracious in their attack of baits, lures and flies and are well known for their spectacular fighting abilities.

Brook trout (Salvelinus fontinalis)
Brook trout are found in a several select lakes and provide extra variety in the Tasmanian fishing experience and represent a challenging but sought after quarry.

Atlantic salmon (Salmo salar)
Atlantic salmon were the first salmonid species to be introduced to Tasmania, but they have failed to establish self-sustaining populations. Trophy Atlantic salmon are stocked into several of Tasmania's lakes

Pest Fish Species

Carp (Cyprinus carpio)
Carp were first discovered in North West Tasmania in 1975 and again in 1980.These populations were subsequently eradicated by poisoning. Carp were again discovered in Tasmanian waters in 1995 this time in lakes Crescent and Sorell. They have not been found in any other Tasmanian waters since this latest discovery. Carp are currently managed by the IFS to contain them to these two waters, and ultimately eradicate their population in Tasmania

Mainland Yabby

Yabbies (Cherax destructor)
All species of mainland yabbies (Cherax.spp) are listed as controlled fish. The only species found in Tasmania is Cherax destructor, which was first released in Tasmania’s midlands, and has since been transported to farm dams and waterways around the State. Yabbies have the potential to out-compete native crayfish and, due to their burrowing habits, have been blamed for dam failures.

Eastern gambusia (Gambusia holbrooki)
First discovered to be in Tasmania in 1990, there are currently several self sustaining populations in the upper reaches of the Tamar estuary. The largest population of Gambusia can be found in the Tamar Island Wetland Reserve Conservation Area where there is unrestricted access to the main estuary. Gambusia are an annual species with enormous reproductive capacity. An average female is able to give birth to up to 450 live young over the summer breeding season. Gambusia is a threat to Tasmania’s native fish and frogs because of its superior competitive abilities and its extremely high tolerance to a wide range of environmental conditions.

Goldfish (Carassius auratus)
Goldfish show considerable colour variation in captivity, but in the wild tend to revert to their natural colour of olive green to golden bronze. Most Tasmanian populations are a result of releases from aquariums and are locally abundant in farm dams and some streams. They are believed to compete with native fish and have the potential to spread fish diseases and parasites.

Redfin perch (Perca fluviatilis)
Redfin perch were introduced soon after trout in the 1860’s. Over the past 30 years, redfin have spread to some of Tasmania's trout waters and into areas of high conservation significance. Redfin have been directly linked to declining trout fisheries and native fish distributions, and are capable of forming large unmanageable populations.

Tench (Tinca tinca)
Tench were introduced into Tasmania from Europe and were well established by the 1880’s. They are usually dark olive green in colour with orange red eyes. They are now widespread in Tasmania. Tench are believed to directly compete with trout and native fish for food.
