Some have been done by different hatcheries although I have not seen a written paper. They have gone beyond that to select the most aggressive northerns and largest florida's to cross and call them tiger bass in one case and in another bulldog bass. There have been several posts on this fourm about the topic. I heard Ken Cook the bass pro and fisheries biologist about 8 years ago talk about several ponds he was stocking with only the most aggressive fish he caught to experiment with the idea. So the idea is not new . I would also like to know if there are any written studies on this topic. There are a number of studies on intergrades { another name for florida/northern crosses of which F-1's are a type} , florida's and northerns in ponds but they don't focus on the aggresive trait but on others. We have that situation in several of our ponds and are keeping an eye on the results. ewest
