there is snagging apparently ...purposely hooking a fish in the gills or mouth... or by letting the salmon swim through your line and get hooked in the mouth... or there is the drifting method where you drift with roe or skein and when it gets within close range of the salmon it gets hooked either by the line flowing through its mouth or because the salmon sucks in water and it happens to get hooked... so there is no possible way other than this to catch salmon on marshmellow other than this?
