first let me say hello Brick and welcome to the group:
You make a very strong point there, the hybrid in barren would cream the fingerlings if they made it to the lake itself untill they were at least 8 inches I have caught hybrids at the Narrows that could and did take 6 to 8 inch shad in one at even 5 pounds these brutes would hit a mercury 10hp if it looked like food I have only caught 3 wal eye so it would be a nice adventure to have another predator to look for.
