Got out for some hook washing Sat am in NW Calgary. Came across a group rigging up at a storm sewer outlet in Beaumont natural area. I checked out their gear and explained very nicely to them that using bait and barbed hooks was illegal. We even commiserated about the silliness of barbed hooks being available. They never even stopped rigging up. I mentioned the size of the potential fines and also let them know about the single fish 35 cm restriction. Then I wandered on to see if they would leave. I checked back about 20 minutes later and they were obviously dredging bottom with bait rigs so I called it in. They were caught with several fish, using bait, and barbed hooks.
They spoke fluent English so there was no question about understanding. They'll either think twice or be more deceptive next time.
Most times people are thankful for the information about the regs and penalties. Although they were polite, it was pretty obvious this group wasn't interested.
Also, I caught a nice 16" buck rainbow. For some extra challenge I hooked him closer to the outlet end rather than the inlet. Made him fight like a +20".
