Unlike other casting methods, fly fishing can be thought of as a method of casting line rather than lure. Non-flyfishing methods rely on a lure's weight to pull line from the reel during the forward motion of a cast. By design, a fly is too light to be cast, and thus simply follows the unfurling of a properly cast fly line, which is heavier and tapered and therefore more castable than lines used in other types of fishing.
The physics of flycasting can be described by the transfer of impulse, the product of mass and speed through the rod from base to top and from the transfer of impulse through the fly line all the way to the tip of the leader. Because both the rod and the fly line are tapered the smaller amount of mass will reach high speeds as the waves in rod and line unfurl. The waves that travel through the fly line are called loops. Determining factors in reaching the highest speeds are the basal frequency of a rod and the transfer of the speed from the tip of the rod to the fly line. At the moment the rod tip reaches its highest velocity the direction of the cast is determined

Dropping the fly onto the water and its subsequent movement on or beneath the surface is one of fly fishing's most difficult aspects; the angler is attempting to cast in such a way that the line lands smoothly on the water and the fly appears as natural as possible. At a certain point, if a fish does not strike, depending upon the action of the fly in the wind or current, the angler picks up the line to make another presentation. On the other hand, if a fish strikes, the angler pulls in line while raising the rod tip. This "sets" the hook in the fish's mouth. The fish is played either by hand, where the angler continues to hold the fly line in one hand to control the tension applied to the fish, or by reeling up any slack in the line to act as a drag on the reel. Most modern fly reels have an adjustable, mechanical drag system to control line tension during a fish's run


Once hooked, a small trout can be easily retrieved "on the reel" or by simply pulling in the fly line with the reel hand while pinching the line between the rod handle and the index finger of the rod hand. It is important to keep the rod tip high, allowing the bend of the rod to absorb the force of the fish's struggles against the line. Some trout will take line in powerful runs before they can be landed. Unlike spin fishing where the line is already on the reel, playing a fish with fly line and a fly reel can present a special challenge. Usually, when a fish is hooked, there will be extra fly line coiled between the reel and the index finger of the rod hand. The challenge is to reel up the loose fly line onto the reel without breaking off a fish (or getting the line wrapped up around the rod handle, one's foot, a stick or anything else in the way). With experience, trout can be put on the reel simply by applying light pressure on the outgoing line. Once the extra line is on the reel, an angler can use the reel's drag system to tire the fish. It is important to use heavier tippet material if it won't spook the fish. The reason why this is important is an exhausted fish can easily die if released too soon. Heavier tippet material enables the angler to land the fish while not over exhausting it
