My understanding is tiger bass are the first generation cross between a Florida female and a northern male both specially selected for their size and aggressiveness. The name is owned by ASF as they developed the cross/method/name. Overton's has a similar fish called tigre. There is some marketing involved for sure but also some substance. They were developed over a 10 year period and tested. They are F-1s but are also different just like all chocolate bars are not Hershey bars.
