Whoa...that fish has a strange set of fins. Adipose but no dorsal. I would put my money on hatchery fish 100% because i have caugth a bunch of hatchery fish with a good bit of the dorsal fin missing. How did it fight, looks like its been in the system a while, although the body looks great. Nice fish bro!
Ok....I spoke to a local shop owner, here is his opinion. This fish was from a snake river hatchery, i cant remeber the name he used but he said their fish go up the tucannon river. The fish get dorsal fins clipped but not adipose. Charlie didnt catch this in the tuc, but it is most likley a fish that either went up the tuc and then down into the walla walla, or a fish that simply went up the walla walla and never the tuc.
