Nirha is intended for noble fish fishing in flowing water and I am interested. The nirha is thrown in the stream above the supposed fish's whereabouts. Swimming with a rod creates an attractive swimming motion for Nirha, which imitates a small fish that has been carried away by the current. Trout love the nirha and can't help but strike. Tip: Nirha is also successfully used in drag trolling behind the decoy plate, so the plate takes care of swimming.
