I agree that stocking from multiple sources may be a good idea. However, Dave Davidson's comment about the impurity of pure strain fish is a major concern. Despite what some people claim, the only accurate way to tell a Florida bass from a northern bass is genetically, so it is real easy to accidentally contaminate a pure strain population. We plan to test fish from a few hatcheries this spring - I will report on what we find.
No one has really looked at the time needed between gene pool refreshments. I would guess that every 5-10 years would be good, and is certainly better than never.
