Habitat Mapping for Eastern Freshwater Cod – NSW

May 2 @ 8:00 am - 5:00 pm AEST

NSW DPI and OzFish Unlimited have joined forces to support the resurgence of naturally recruiting Eastern Freshwater Cod in the Wilsons River.

The Eastern Freshwater Cod (Maccullochella ikei) is an endangered species listed under the threatened species Act in NSW and Commonwealth law (NSW DPI). The species was once prolific through the Clarence catchment and the Richmond River in Northern NSW. However, as a result of habitat degradation, invasive pest species and poor water quality they have become locally extinct in the local region with some stocked populations persisting in local tributaries.

NSW DPI Fisheries are looking to release Eastern Freshwater fingerlings on an annual basis, and with OzFish and their dedicated volunteers, we want to ensure their best chance of survival to re-populate the local region. To do this, we’re seeking passionate volunteers willing to get involved with Fisher Science activities, in this case habitat mapping to scope out the most suitable section of the river to stock fingerlings.

All of the data that will be collected from these activities will assist NSW DPI with suitable fingerling stocking locations. We will be carrying out two habitat mapping methods for this event:

  • Identifying location of refugial pools and depth.
  • Identify instream habitat, complexity, channel shading and surrounding habitat types (e.g boulders, aquatic plants, etc).

For this event, we’re encouraging those who are willing and relatively fit to bring their kayak along and help out with the in-water activities.

The kayaking route is approximately 10km and we expect it to take approximately 8hrs to complete depending on the flow of the river at the time.

Fruit and snacks, and lunch will be provided for the trip. Please bring your own water bottle with enough water to last the whole 8 hours.

Please note that this activity may be physically demanding, where you will need to carry your kayak through certain sections of the river. We also emphasise that you will need to be a confident swimmer to be able to engage with water activities. When registering, please fill out the correct information that is relevant for you.

It is a requirement that you register your attendance so we can coordinate vehicle pick up dorp off arrangements.
