A whopping 678.49kg of Tilapia, European Carp and goldfish were removed from the Robina waterways on the Gold Coast. Since its inception in 2016, the Gold Coast Pest Fish Classic which is run jointly between council and My Catch Australia, has caught and removed over 4,682 kilograms of pest fish. "We know in South East Queensland, tilapia and carp are significant problems for the environment," Invasive Species Council acting CEO Jack Gough told Yahoo News Australia. "In freshwater environments, the next candidate in our ecosystem for extinctions we'll be seeing."
