Without doubt, the biggest disappointment I've had in my new 3.5 acre lake, is the Florida bass and the degree to which they "learn" about lures. I fly fish almost exclusively but even very good conventional fisherman have a very difficult time catching my bass. The only way they can be caught is to use the small bluegill they feed on as live bait.
Very disappointing. Over time I'm introducing natives in the hope that this "learning" can be overcome. Knowing what I know today, I would never stock a Florida, or F1 or anything with any Florida genes...they just aren't worth it for me.
