That guy was certainly taking a risk calling out the bad behaviour, but if we all just turn a blind eye to the poachers or people who may just not know any better it will be our fishery that suffers. I certainly agree with the DFO officer's recommendation to call it in on the report line, but sometimes a respectful discussion to call out the bad behaviour might create better awareness.
We spotted a guy on Facebook Market Place advertising sale of illegal crab. Would have been easy to reply and show up to challenge him for the illegal sale, but instead called the DFO report line. Got through to a real person who took the report and details of where the FB add was etc. If everyone reported what they see on the water it would be interesting to see if DFO could keep up...maybe they would actually get more officers!
