List is really ridiculous
.
I mean there is Carp all over South Africa, that competes directly and indirectly with some of our indigenous species, they also eat eggs and muddy clear water with their feeding habits. The same goes for Bass & Trout that eat smaller and juvenile species.The Clanwilliam Redfin is a threatend vulnerable fish that is being eaten by Smallmouth Bass & the same goes for the Fiery redfin. Bass also competes with Largemouth Yellowfish for food in the Vaal.
There are numerous other species like : European Perch; Tench; Grass Carp; Mosquito Fish; Israeli Tilapia; Bluegill... the list goes on. Yet nobody is doing anything about that matter. I've even heard there's a law that now gives Carp the right to live in South Africa. Compare this to places like Australia & New Zealand where carp may not be returned to the water.
The species on the list is predominantly tropical and requires warm water year round, which for almost all of South Africa is not possible due to cold winters.
It's really ridiculous. They should rather focus there efforts on the current invasives and only ban the fish that pose a real legitimate threat to some of the ecosystems.
