The whole reason we shoot the carp, and other invasive, or rough-fish, is to remove them from a water-way. If you eat them, that's great. If you don't, and most people don't, that's fine too, but DO NOT release them back into the water. We bowfish to lower the numbers of thesefish in our lakes, creeks and rivers. Bowfishing is not catch-and-release. Make sure you dispose of them properly (meaning not in a parking lot or on the side of the road somewhere). Alot of us use, or have used them for fertilizer in our gardens, beneath newly planted trees and bushes, and some of us have farmers that mulch the fish up for their crop-lands.
