Same way as they got into the Missisipi and Great lakes system in the USA.

They are a great tasting fish and breed very easily so they were being tested for use as a food fish in aqua culture at the aquaculture and fish research centre on the Elands river.

There as a floods, holding dams broke and they are now found from below loskop dam wall all the way to the coast where the Rio do Olifantes mouths into the Indian Ocean in Mozambique.

They grow to in excess of 25kg and are a danger to boat traffic as they get irritated by the sound of the props in the water and jump excessively when irritated. Some bad injuries cause by 15kg fish landing in a boat doing 60km/h on the water
