Many anglers today release their fish but I'm surprised how many never bother to crush down their barbs. Barbs are tenacious and can be very difficult to remove, almost impossible to extract without injuring the fish, sometimes quite badly. These difficulties can be removed easily by using needle nose pliers to collapse the hook's barb and or by removing 1 or 2 shanks of a treble hook, the remaining single will hook very well by itself. This nice brown trout gave me quite a tussle and was released without any harm by using a spinner with only a single, barbless hook.
