Another piece of the puzzle. It appears the adipose fin is a major sensing organ for salmon. Information about it's surroundings is picked up by that organ. With the adipose removed, the chances of a fish returning to it's birth/release river are significantly decreased. That could be a major reason why so many clipped fish fail to return.

Ok then..Lets stop cutting them off. Let fish them though and have a limit if it is needed but again why have limits on any fish? I think there should be limits though.

You might want to reread the study as you are stretching the truth.
The fact is that lot's of clipped fish make it back to their streams.
The adipose fin helps them in fast water when they make it back.
The study suggests that it may be 10% of the clipped ones might not survive.
Of course they maybe wrong as they would need more studies to prove or disprove.
Even if it was found that 10% of the clipped did not make it back all a hatchery would have to do is increase clips a mere 10% more to negate the possible problem.

Until there is rule change all hatchery fish should be clipped.
I have personally been on fishing trips that hammered coho but only found one or two clipped.
Not something I liked to do.
