From TPW via Eddie -- "Then in the list of fish not allowed is "Tilapia, Family Cichlidae
All species of genus Tilapia (including Sarotherodon and Oreochromis)"


From FishBase -- Oreochromis mossambicus
Mozambique tilapia -- Cichlidae (Cichlids), subfamily: Pseudocrenilabrinae

Now you tell me how they will enforce this against fish marketer/growers and not the pond owner who has tilapia and predators but who might also sell a few to the fish market guy. I am not saying it is wrong to do so or can't be done, but would like to see how it is justified by TPW on biology grounds. If it is not based on biology then it is economic regulation and must be based on rational non-discriminatory grounds. For example can one person grow tilapia for sale as a food item from a aquaculture operation while the guy who raises them in his pond to sell them at his fish market can not ?
