I agree that an increase in minimum length anywhere from 10-12 on the big G and a smaller creel limit of 15 or 20 would help the fishery. I don't think it would be a problem to selectively change the regs for individual bodies of water. Big G could certainly handle it. As for how MS does it, my daughter is considering going to MSU next year and we did a campus visit earlier. They have a sizeable body of water on Campus that the state uses to test their white crappie programs and experiments on. MS is much better funded and active on their crappie management!
