Regarding catchability, if you plan to fish pretty hard you might be better off stocking different LMB different years. LMB, especially Fla LMB, rapidly adapt to fishing pressure by becoming very difficult to catch. So do their progeny via epigenetic effects.
Stocking some naive LMB every year helps combat this process, as does emphasizing northern genetics.
