I wouldn't stock the HBG with the RES and forage. HBG are very predatory with big mouths. They are cheap to source even at bigger sizes. Leave them out until your stock the other predators. Let your forage fish grow unmolested. RES will eat a few but it will be minimal at worst.

If it was me, I would work with Nate and see if I could get RBS instead of HBG. Nate is in the forefront of exotic and unusual fish species and stocking combinations. I think he could help you get a source of RBS in your area. I think you'd be happy with the RBS results compared to HBG for your planned fish stocking combination.
