I've never until now heard of people who are salmon bigots.   In Alaska , anything that has naturally migrated on the wind or currents or introduced though bird droppings and such is considered "invasive".      Oh....the blue crabs are migrating....oh the butter and eggs flowers have migrated, oh it's a bird that I've never seen in Alaska before..........EEEEH!  Kill it.....Kill it!    It doesn't beeeeeeeelong hhhheere!
