I've seen lamprey on a chinook salmon, fall run, main stem of the Toutle
River, Chicken Heart hole, 1968. The pike minnow is so evasive on the
Columbia there is a bounty of $4 per fish over 11 inches, has been for many,
many years. Many retired anglers make thousands of dollars a year returning
these fish for the bounty. There is an upper limit on these fish where you
get more money per fish ($5 I think) for catching a bunch of these fish. If
I remember right it's like at 200 fish turned in. Everyone I catch, no
matter the size gets knocked in the head, and they are a pretty decent food
fish smoked. They put Tiger Musky in some of our reservoirs to help control
these fish.
