Doubt if they are miss clipped as after handling many thousands of them a bad clip is deformed. To be honest a bad clip is very easy to see and distinctive.

I know what a wild adipose fin looks like and these are defiantly not "wild" adipose fins. And what about the deformed dorsal?

no idea but Bingham used to do a blind cwt that is a hatchery fish with CWT but not clipped. it is a way to see if the math tracks with clipped fish. not sure if they still do it.

coded wire tag / it is a tiny wire with a numerical on it that is imbedded in the fishes nose so to speak when they are fry.

Another possibility is the volunteers that use remote site incubators ( RSI ) which get eggs and hatch them and release the fry. They use bio rings rather than gravel and but the bio rings are smooth. Still to much flow will make them move around . These fry are not marked before release.

One final thought is that there is a difference between a wild ad fin and hatchery. Bit of an old wives tale for normal timed Coho. Now the late timed wild Coho do go against that with a rather large ad fin but that tends to be proportional to size and predominantly West Fork & Middle Fork Satsop fish that return mid Dec through Jan.

I was under the impression that unclipped hatchery fish with a CWT are part of what is called the "double index tag group" and that most hatchery stocks, or maybe management areas had this going on with a static 5% of the smolt release group. It is done for the reasons as said above, to better the odds of getting data back. I wager that 5% is more than the missclip rate for smolts.

Back in the 80s/90s WDF tried to see if hatchery Chinook would establish a "wild" run in the Deschutes. Unmarked fish did come back but the number was such that it could have been "drops" or wild fish.

Cowboys quick-reporting past 3 days:
4000 chum dominated the catch with about ~4 chum for every coho. Coupla kings retained.
