Hi Christian,
    I do not know if you try this method, I saw it in one of the FAO
Publications about fish marking. The method is very simple you just cut a
piece of adipose fine or other other fin. You will easily differentiate the
marked fishes because the new growing part of the fin mostly grown in
different color and you can easily detect the trace of cutting.

Best regards
