Earlier this year the Inland Fisheries service (IFS) received a report regarding the possible presence of redfin perch (Perca fluviatilis) in Bronte Lagoon.

Bronte Lagoon is thought to be free of redfin perch, however they are present in the neighbouring Bradys chain of waters.

In January 2025 the IFS conducted an extensive, full day, boat electrofishing survey on Bronte Lagoon with no redfin perch found.

Earlier this month the IFS returned to Bronte Lagoon and conducted a net survey in all likely habitats around the Lagoon, involving the overnight set of 30 box traps and 12 fine mesh fyke nets. 

Brown trout, rainbow trout, tench, short finned eels and spotted galaxias were caught, however no redfin perch were encountered. 

There have been no additional reports of redfin perch in Bronte Lagoon since the initial report earlier in the year.

While redfin perch have not been confirmed in Bronte Lagoon, the IFS is urging anglers to remain vigilant and report any suspected sightings (or captures).

Take a photo of the fish if possible, or if a carcass is found and it is practical to do so, it can also be retained. Please take note of the location where any suspect fish were seen (or caught), as well as the date, and contact the IFS promptly on 1300 INFISH or infish@ifs.tas.gov.au

Redfin perch are an invasive species that were introduced to Tasmania in the 1860’s, and are now established in many areas of the state. Due to their aggressive nature and ability to reproduce rapidly and overpopulate water bodies, they pose a threat to our native fish and trout.
