Burdekin residents are being invited to cast a line for knowledge this May at a free community event in Ayr celebrating the vital role of local waterways in supporting native fish populations.
Hosted by NQ Dry Tropics to mark World Fish Migration Day on Saturday, 23rd of May, the family-friendly event at Hutchings Lagoon aims to highlight how connecting rivers and wetlands ensures a healthy future for local angling favourites.
Many iconic North Queensland species, including barramundi and mangrove jack, rely on moving between freshwater and the ocean to complete their life cycles. However, barriers such as weirs, dams, and thick aquatic weed chokes can prevent juvenile fish from reaching upstream nursery habitats.
NQ Dry Tropics Senior Project Officer Georgia Robinson said protecting these migration pathways is a key priority for the region’s natural resource management.
“Since 2008, NQ Dry Tropics has partnered with Lower Burdekin Water, Burdekin Shire Council, and local landowners to remove aquatic weeds, rehabilitate wetlands, and install fishways,” Ms Robinson said.
“The fishways include areas for fish to rest as they swim against the flow, helping more juveniles make their way upstream to feed and grow.”
The event offers a hands-on look at the science behind the scales. Attendees can witness a barra fingerling release at 10:30am and watch live demonstrations of the Burdekin Shire Council’s specialised weed removal boats in action.
“We’ll be explaining how fish migrate and the important role that weed-free wetlands and healthy vegetation play in keeping populations healthy,” Ms Robinson said.
In addition to the demonstrations, visitors can browse stalls from local organisations focused on water quality and responsible fishing. There are also lucky door prizes up for grabs from local businesses.
The event runs from 9am to 1pm at the Lower Burdekin Ski Club, Hutchings Lagoon, Maidavale. For more information, visit www.nqdrytropics.com.au.
