Fly fishing, in all it’s variations and sub-areas (casting, fly tying, etc), centres around a single goal - To successfully tempt a fish (Most commonly a trout) to take an artificial fly as a food item. Sighting, hooking, playing and landing the fish are also important parts of the successful fishing experience, not to mention being able to get the fly to the fish in the first place, by the unique casting methods utilized solely in fly fishing.However, along with all that work, and the practice of the skills involved in bringing it all together at that crucial moment, comes that pivotal element of convincing the fish that what they are considering is indeed food-like in nature. Without this key element, we can forget the rest, and this is the one step of the exercise which is dependant upon the decision of the fish, rather than ourselves.In this, fly fishermen spend untold amounts of time researching, studying, and imitating countless insect types in aid of presenting a believable decoy to their quarry. We tie our flies, the fish takes it, our efforts paid off, right?
