Snagghing of salmon is against the law in Oregon.If a salmon is accidently snagged and released, no foul. When pulling spinners thru a school of fish you can snag one.
Case in Point, I was fishing on a Creek in the Siletz drainage area for Jack salmon that follow the big Chinnok upriver to the hatchery. I was using small spinners and hooked a dorsal fin of a thirty pound Chinook. After a terrible tussel, got the fish to shore and removed the barbless hook form the fin and revived the fish to contnue its trip. When I stood up there was Officer Dougens standing next to me in full camo gear. Scared the gee's right out of me. He checked my license and tag and told me that was one of the funniset fish catchs he had seen and really apprecited my release method of the fish. Checked my two jacks and wished me good fishin. He walked back into the woods and dissapeared.
In your situation, never confront a fellow fisherman on this subject if you see a violation, leave contact OSP and return to watch. Avoid the conflict. Be safe not hurt!
