Down in Burrendong dam.NSW we have red fin [english perch] mixed in with the native fish.it is an offence to release them, deamed feral ,Just wondering how quick they grow.??The fish are around the 700 gram mark at the moment.The locals say in winter 5-7 pounders are a common catch.Aparantly they are cannibs and give the native fingerlings a cannng.
