The Exocoetidae are a family of marine fish in the order Beloniformes class Actinopterygii, known colloquially as flying fish or flying cod. About 64 species are grouped in seven to nine genera. While they cannot fly in the same way as a bird does, flying fish can make powerful, self-propelled leaps out of water where their long wing-like fins enable gliding for considerable distances above the water's surface. The main reason for this behaviour is thought to be to escape from predators.
Variable use fly-fishing reel
A fly-fishing reel has a reel body with a reversible pawl and an arbor. A spindle shaft with a gear rotates on the arbor, the gear and pawl limiting the direction of rotation. A spool and lockably engaged drive plate rotate on the spindle shaft and are secured thereon by a drag capsule which attaches to the spindle shaft. Tightening the drag capsule on the spindle shaft forcibly engages friction surfaces on the spindle shaft, the spool, the drive plate, and the drag capsule to provide an adjustable dual disk drag mechanism, as well as securing the drive plate and spool together. The spool can be readily replaced with a different spool and the spools are preferably reversible on the spindle shaft. A winding handle is attached to the drive plate to provide direct-drive action, or is attached to the drag capsule to provide a non-return action.

Fly Fishing Method and Apparatus
A hook-less fly crafted on a core other than a hook is described for attachment to a line at a material distance from a distal circle hook. One or more fly(s) may be attached to a single line at a point above a single circle hook. The separation on the line of hook from fly requires only the fly to enter the fish's mouth. The hook, when a fish takes the fly, is externally located. Striking the rod in response to the fish taking the fly draws the line through the fish's mouth and engages the distally located circle hook into the outer jaw. Hook set offered by the method is diametrically opposed in direction compared to conventional fishing. The method prevents the hook from piercing internal organs and facilitates hook extraction. The method further overcomes the physical limitations imposed on circle hook use by conventional fishing methods. The method promotes the survival of fish following release. The design, construction and means of attachment for the hook-less fly is further described. A line orientation structure can be provided on the hook-less fly. Various line attachment devices are disclosed for the hook-less fly.
