Fish need to travel along waterways to breed, feed and thrive. Some fish even need to move between freshwater and saltwater to breed.

Barriers in waterways (such as weirs, roads and floodgates) act as roadblocks to fish moving along waterways.

The Reconnecting fish habitat project is working to find solutions to help fish move around these barriers.

This includes working with barrier owners (such as local councils) to either remove the barriers or construct fishways (also known as fish ladders).

Actions from the project include removing an obsolete weir on Richmond River near Casino, monitoring fish movement at Kyogle Weir Fishway and improving fish passage on the Brunswick River.

“Adding a fishway to a weir is a win for the ecology of the river and for fishers upstream, as native fish can return to areas where they have been previously blocked from since the weir’s construction.”   Scott Nichols (DPI – Fisheries)
