Well, Pat I was hoping/expecting you would say all Floridas.

I understand what EWEST is saying about avoiding any negatives in a discussion, but I have to be frank and say I'm disappointed to hear that your F1's also may have the same problems as Floridas. That is disappointing indeed.

I tried introducing natives into my pond with uncatchable Floridas and found it did not help at all. The natives quickly "learned" the habits of the Floridas, it seemed because they suddenly became uncatchable and came from another pond in which they were imminently catchable.

I've had hopes that F1's by themselves would prove to be a better solution. Time will tell.

Thank you Pat for sharing your data and adding considerably to our own knowledge.
