"a ball to catch and good eatin' too"

The above quote refers to oscars (Astronotus ocellatus) and tilapia (Tilapia spp.), just two of the many exotic fish that have invaded South Florida. The Herald-Tribune reports that more than 53 different non-native species can now be found in the state, from the aforementioned fish to hoplo catfish (Hoplosternum thoracatum) and jewelfish (Hemichromis bimaculatus). Local biologists are worried that people that consider the introduced fish a benefit rather than a potential problem may be spreading them to new ponds and other fresh water bodies.
