I don't believe F1 LMB growth rate would be significantly different than that of Northern or Florida LMB. The difference will be maximum size potential determined by average life span. Assuming the right sizes of forage are available to a LMB throughout the life of the fish, it has the potential for maximum growth limited by lifespan. I'm sure genetics play a role in growth rate, but there is no specific "growth-rate" for any fish....all depends on forage, stocking rate (population size), and environmental conditions.
