Accept that if you want sox outside of the chuck, then you are 'harvesting', by the only available method, not sport fishing.
Don't want to participate? Then don't.
Get your fly rod and throw chironomids at rising sockeyes all day. You will have satisfied your need to keep all your fishing related activities narrowly defined as a 'sport'. You will also be buying your sockeyes at Safeway.
Does anyone really think that the average fisherman on here really relishes the thought of spending their afternoon flossing? If there was an alternative, if they would bite in fresh water, we'd use it. Just like we do for every other species of fish and salmon. And it would be far more enjoyable.
But don't take any wooden nickels from a guy who claims to be doing anything other than harvesting when it comes to sockeye. Flossing is, in effect, a micro-scale commercial fishery, 2 fish per day. No more sport involved than if you were hauling them in with a net.
Or one final way of looking at it: would you prefer that all sport fishermen were banned from flossing sockeyes? Thereby leaving 100% of the run for the FN and commercial guys? Would that make you feel better?
