Salmon hatcheries clip off the adipose fin they hatch so when they return to spawn they can count how many versus wild return back. They have a diversion off from the river that guides the salmon through a narrow passage that they have a window to see the fish pass by they do a visual count. Not all Salmon go through it but they get a percentage that do which gives them the percentage they need to come up with how many return each season.Hello; I seem to recall that fisheries biologists would notch fins on hatchery fish to be released into the wild. .
"its just a bother" lol.. dont worry about the fact that your severing a bone from a living creature fully capable of feeling pain. Im not against it i just think that was funny loloh and i dont mean cut the whole fin off, to be more clear its probably about half an inch before the kink appears. i would just have to cut through the bones that go through the fin. I wont do it anyway. it would cause too much bother.

Maybe not in the fins themselves, but in the bones, yes.
And saying that it's just the fins doesnt really fix it, everyone has lost a fish from nipped fins, wether it's from stress or infection.
Don't do it. Sell your fish if its appearance bothers you so much.
