yes I was there and they had a good presentation. What I learned was that Hyco's Tillipia population is what's holding the bass size down and the crappie numbers down . They said it's the competiton for breeding grounds ad food that's messing up e system They don't expect the drum to wipe out the tilapia so much but they hope to use them to support the red drum and make Hyco a unique fishery. The drum eggs can't hatch in fresh water so it will be easy to manage.
