So today I caught a hatchery steelhead in a Columbia River Trib. The odd thing that I noticed about the fish was that it not only did not have a adipose fin, but it also had a missing ventral and dorsal fin. I have never caught a hatchery fish with three fin clips. I have seen a dorsal and adipose on the Lower D a few years back, but not three. Does anyone know of a hatchery that clips multiple fins? Also I have heard that the loss of the adipose fin does not affect swimming, does the removal of any other fin affect swimming? I find it odd because of the size of the fish.
