Nah, but being that you called me out on it, I'll just chime in to say what he said is true, Grass Carp can eat its own weight in vegetation per day, so they can cause a lot of destruction, which could pose potential risks for your hatchery raised Steelhead.
Not all Carp are the same, Common Carp are the least of ones worries when it comes to Carp, Asian Carp are what give Carp a bad name (Grassers, Bigheads, Silvers). If Common Carp were so destructive, then ODFW and all the other states would take measures to eradicate them, you don't hear about Common Carp being eradicated from a body of water since they can fit in an ecosystem, Asian Carp will wipe out an ecosystem.
