Just an FYI, using RAPP to report angling violations is only good if it concerns trout or steelhead. DFO are the guys that deal with salmon calls. Im not saying conservation officers dont ever answer to salmon calls because they do, but if you have noticed when you call RAPP they tell you to call the DFO radio room [i have done it and sadly I often get the answering machine]
nevertheless, things like snagging fish are hard to prove in a court of law unless you as the witness are willing to testify. Officers are looking to build a solid case that would do well in court and therefore respond to calls where they know they can take good evidence. for example, retaining wild coho or steelhead right now would be a great opportunity for DFO to come out, given that others witnessed and can identify the guy who did the poaching. It is not a question of where the fish is hooked just the fact that it was seen caught by mr. blue and the same species as reported is dead on the beach is evidence enough to charge mr. blue. If someone said mr. red snagged a pink, it is harder to prove unless there are videos or someone who is willing to testify, and because pinks are open they would have to give mr. red the benefit of the doubt, even if there were other wounds in the fish [the fish could have been injured, etc.]
this is what the officer told me first hand.
