I was in Alaska 2yrs ago, we could throw anything we wanted at them and not get that reaction bite. we may have got 3 or 4 all week that were on hard baits, Put skeens back on you got bit 50% of the time. Guys say they don't feed, but in my experience they sure will eat up some eggs, I am told they do it for dominance, how true that is I do not know.
