Booming goldfish

Busselton may be famous for its fishing, but did you know that it is also home to some of the biggest, meanest feral goldfish in the world? Feral goldfish of over 40cm and weighing up to 2kg have been recorded in the Lower Vasse River and since the last removal program in 2013 the population is booming.

Invasive species such as goldfish degrade natural ecosystems and do not belong in our waterways. Feral goldfish prey on native fish species and compete with them for resources, they also contribute to poor water quality by stirring up excess nutrients in sediments.  

The high population of feral goldfish in the Lower Vasse has a serious impact on the immediate ecosystem but also on the Ramsar-listed Vasse Wonnerup wetlands further downstream, there is a serious risk of invasive fish spreading to other local tributaries which feed into the wetland. 

Action on invasives

OzFish Geographe is using an innovative method to remove goldfish from the river with pod traps. These baited, pyramidal traps are used to minimize bycatch and disturbance to native species.
