If you really feel like what you are doing isnt a problem, go speak with a game wardern about it and see how they react.
Native or non-native, wild or aquacultured, items should not be released or re-released into the ocean. Even in your circumstance where the likelihood of something bad coming of it is miniscule, it isnt worth it.
It isnt a responsible action, and stuff like this is what makes it progressively more difficult to get certain breeds of fish, or to harvest organisms from certain locations regardless of what good intentions you may have had.
