Todd, Tony, George, I agree with all your points. It's all about the customers goals for that particular pond.
For instance, take a pond where they want to manage for trophy BG, have a FA problem, and the pond is stocked with LMB as a predator. The goal is to have the LMB concentrate on eating the YOY BG. Would Hybrid Tilapia (i.e. typically 90+% male) be a better choice to stock or still stock 50%/50% ratio of non-hybrid Tilapia?
