I think you are better off than you believe. If only a few 5 or 6 Fla LMB survived to spawn then those genes are set in your pond. If only a few of the F-1s survived to spawn, more of the same. There are several published studies and some unpublished as well that show that , in southern waters , Fla genetics tend to increase over time where stocked into Northern LMB lakes.
I would want more info based on your facts before I pulled the GShad lever.
I wanted some Texas gizzard shad experts to chime in, but you did get a Mississippi expert to chime in.
That is like catching a "bonus" fish when you are fishing for something else!
