Dang it! I know sometimes I sound ticked on the forums. I was agreeing with you about killing them, saying I was a big fan of derby's..... which one time removed 1400 of them in a single day. If you see it, kill it. Just kill it clean. None of this ninja stuff. I can't say for them to be all eaten, either. You would have to analyze the impact on the local fisherman's livelihood.
