Fin-clips are required to provide an indentification marker for stocked fish under the guidlines of the MNR. Cheapest way to mark a fish = fin clip.

These are adipose clips in this case....steelhead that size tend to take them with very little mortality. Better than lopping off a pec fin.

More than 50% of stocked fish on the U.S. side are NOT clipped.

This program on the Saugeen with the Ontario Steelheaders and LHFC has already boosted the return rates of adult steelhead on the big river by staggering amounts.....awesome....and it will just get better!
