Check out the ferals invading the SwanPermalink Mar 22
The Swan River Trust will feature an eye-catching display of live feral fish in its marquee at this year’s Autumn River Festival on Sunday, April 1, to draw attention to the serious problems caused by people dumping unwanted aquarium pets into Perth waterways.
Introduced exotic fish – ranging from Asian koi carp and giant goldfish through to South American gambusia and even some perch native to other Australian states – are threatening the future of some native fish in the Swan Canning Riverpark by damaging habitats and preying on eggs and young, and it is critical people know that they should never dispose of their unwanted fish in waterways.
The Trust’s marquee will also feature an experiment to show what happens when fertilizer is added to a jar of river water – a green, gunky mess. There will be a kid’s colouring-in competition, information on all sorts of river animals, including dolphins, access to a microscope, and even a display of feral snails – so make sure you drop in.
The Autumn River Festival - from 10am to 4pm on April 1 – is in Riverside Gardens in Bayswater. It’s a great day of free fun for the family, with a range of community stalls, arts and crafts, live entertainment and children’s activities.
