Glad to see the tremendous interest in trying circles for flossin' reds this year as a means to reduce the incidence of foul-hooking fish.
As virtually all of the in-river effort targeting salmon shifts almost exclusively to targeting sockeye, another area where we as anglers can make a HUGE difference is in our choice of fishing spots. Flipping for sockeye is exclusively a bank-based affair involving shallow wading. As the masses take to the banks, their/our collective ability to trample the banks and nearshore vegetation with thousands upon thousands of boots cannot be understated. Think buffalo stampede and you've got a pretty good idea.
Remember that most of the juvenile rearing habitat for coho and chinook resides within 6-8 ft of vegetated banks, areas that provide shade and cover for young salmon. PLEASE respect the posted "NO BANK FISHING" zones that were specifically chosen to protect nearshore vegetation from trample impact. This includes those of you wading from an anchored boat... an option which is totally legal if one actually remains 10 ft or more from the bank. The problem is most folks exercising this option DON'T stay at least 10 ft from the shore once they have a fish on. The instinctive tendency is to back up with a hooked red to facilitate landing that fish in the shallows.... right up onto the vegetation that needs protection!
Choose your fishing areas accordingly... armored banks and bottoms lined with cobble and gravel that can withstand heavy foot traffic.
If you are going to opt to fish closed banks by exercising the 10 ft loop hole, make the pledge to land that fish in deeper water (challenging as that may be) and avoid backing up onto sensitive nearshore vegetation. That means fishing with a capable partner with a landing net. Beaching fish is neither a legal nor ethical option.
