I find this interesting in that our KS guys refer to both LMBxSMB and SPBxSMB as "Meanmouth". It has been said to me that the spot/smallie is very common compared to LMB/SMB. 3 years ago I extracted an unknown individual that we could not confirm, Bio had me haul it home and "see how it turned out".. We know after many pics and a fin clip, it's a SPBxSMB.
I see good and bad with these, SPBxSMB will never be anything more than either parent but LMBxSMB could be an issue if out-breeding depression occurs to any degree, I don't know for sure. It would be interesting to see some confirmed crosses and then keep records of the ratios of fish and what happens over a 5-6 yr period.
