The florida or southern strain of largemouth grow faster and larger than the other largemouths. Most of the impoundments int eh southwest stock the florida strain. They grow fast too, naturally I think most places get like 6 or 8 months growing wehreas is the SW they get all year growing. In south Ga the growth rate for bream (bluegill) is like 4 inches a year, so extend that for bass. I havent read anything about the growth rate of the southern strain in the SW though.
Fishing in the midwest there was several kinds of bas sbut I never heard that they were hybrids. Largemouths, smallies, rock, and redeye, and a couple others. I never heard of the hybrid thing before though.
