New community resource for the Upper Murrumbidgee

FeralFishScan is a new community website for collecting evidence of feral fish in the Upper Murrumbidgee catchment. Feral fish (also called 'pest fish') cause enormous damage to our rivers and native fish populations. If you have seen or caught feral fish in your local area, record the details here to help identify feral fish hotspots across our catchment.

Research tracks tagged Carp in the Murrumbidgee

Carp movement is being studied as part of the Upper Murrumbidgee Demonstration Reach Carp Research project which also includes a trial carp trapping program. This project is a partnership between Bush Heritage Australia, NSW DPI (Fisheries), the Capital Region Fishing Alliance and the NSW Recreational Fishing Trust. For information about the UMDR Carp Research project go to
A total of 31 tagged carp have been released into the upper Murrumbidgee River, upstream of the ACT. The tagged carp are marked with a long yellow tag near their dorsal fin. These carp are implanted with electronic tags so their movements can be tracked as they move along the river system. If caught, please RELEASE tagged fish and report details to the number on the tag. A reward will be given for making a report. Please take photos if possible.
