You're not poaching unless you are doing it on purpose, everyone ends up snagging a fish once in a while inadvertently.
I belly hooked a steelhead a few week's ago on the Saugeen. In about 6ft of water out in the middle of a run, lol..
I thought I had the fish of the day the way it took off downstream and me chasing behind it. Thought it was a 15lb fish for sure...It was about 5
It happens!
