there arent many natives around that can grow as fast or breed so young and produce so many young that can feed on most things. so bag limits or no fish zones are needed for natives to keep populations ok but this is another kettle of fish. its all about the fish biology and sadly, our natives no longer have what it takes to handle built out areas so well. we are going to go from trying to stop them, to accepting they are here to stay and then our kids will probably embrace them and make money off them or eat them. us older generation will scream murder and the kids will think they are native just like they will think our society is native to oz too!
