I have a pond that was newly stocked with fingerling 3-4" smallmouth bass in October of 2005 and was wondering how old are smallmouth when they reach sexual maturity? My smallmouth are 2 years old and I've seen several that are 10-12 inches long the past few days. Is it a certain age or is it the size that determines spawing capabilities.

Is there a difference with spawning age/size for largemouth vs. smallmouth or they the same?

Any info would be greatly appreciated. Thanks!
