I've noticed the same thing on green river fish. Half the fish I've got this year have had a scar or a rip of tail. They need to do something about those things. Several times while fishing at Illwaco for salmon we had seals follow and try to take the fish. A couple years ago a when you had to turn kings loose. A seal came all the way up to the net while the fish was in it. We had to motor away to get away from the seal.
