Techniques for fly fishing differ with habitat (lakes and ponds, small streams, large rivers, bays and estuaries, and open ocean.)
Flies are tied in sizes, colors and patterns to match local terrestrial and aquatic insects, bait-fish, or other prey attractive to the target fish species.
[6] Tenkara originated in the mountains of Japan as a way for professional fishermen and inn-keepers to harvest the local fish, Ayu, trout and char for selling and providing a meal to their guests.
"[7] This refers primarily to Ayu fishing, which commonly uses a fly as lure, uses longer rods, but there is no casting technique required, it's more similar to dapping.
[10] Other than a few fragmented references little was written on fly fishing until The Treatyse on Fysshynge with an Angle was published (1496) within The Boke of Saint Albans attributed to Dame Juliana Berners.
"[11] The art of fly fishing took a great leap forward after the English Civil War, where a newly found interest in the activity left its mark on the many books and treatises that were written on the subject at the time.
He received a royal warrant and became the official supplier of fishing tackle to three successive monarchs starting with King George IV over this period.
It was the first comprehensive work related to the entomology associated with fly fishing and most fly-fishing historians credit Ronalds with setting a literature standard in 1836 that is still followed today.
[19] According to Ernest Schwiebert: "Ronalds is one of the major milestones in the entire literature of fly-fishing, and with his Entomology the scientific method has reached angling in full flower.
[21] The material used for the rod itself changed from the heavy woods native to England, to lighter and more elastic varieties imported from abroad, especially from South America and the West Indies.
However, these early fly lines proved troublesome as they had to be coated with various dressings to make them float and needed to be taken off the reel and dried every four hours or so to prevent them from becoming waterlogged.
[23][24] The founding of The Orvis Company helped institutionalize fly fishing by supplying angling equipment via the circulation of his tackle catalogs, distributed to a small but devoted customer list.
[22] By the mid to late 19th century, expanding leisure opportunities for the middle and lower classes began to have its effect on fly fishing, which steadily grew in mass appeal.
[28] In the late 19th century, American anglers, such as Theodore Gordon in the Catskill Mountains of New York, began using fly tackle to fish the region's brook trout-rich streams such as the Beaverkill and Willowemoc Creek.
[28] Albert Bigelow Paine, a New England author, wrote about fly fishing in The Tent Dwellers, a book about a three-week trip he and a friend took to central Nova Scotia in 1908.
Fly fishing in Australia took off when brown trout were first introduced by the efforts of Edward Wilson's Acclimatisation Society of Victoria with the aim to "provide for manly sport which will lead Australian youth to seek recreation on the river's bank and mountainside rather than in the Cafe and Casino.
Movies such as Robert Redford's film A River Runs Through It, cable fishing shows, and the emergence of a competitive fly casting circuit have added to the sport's visibility.
Trout usually only come to the surface when there is a large bug hatch (when aquatic insects grow wings and leave the water to mate and lay eggs).
There are exceptions to this rule, however, particularly during the summer months and on smaller mountain streams, when trout often feed on terrestrial insects such as ants, beetles and grasshoppers.
[35] In order to deceive wary trout, or to reach deep runs where salmon may lie, the fly angler often needs to wade to the right casting position.
In deep water streams, an inflatable personal flotation device (PFD), or a Type III Kayak fishing vest, adds a degree of safety.
Dry fly fishing on small, clear-water streams can be especially productive if the angler stays as low to the ground and as far from the bank as possible, moving upstream with stealth.
[38] Dr Bell tied artificials to represent the insects that he found in the Blagdon trout, including bloodworms, midge and sedge pupae and beetles.
Saltwater species sought and caught with fly tackle include: bonefish, redfish or red drum, permit, snook, spotted sea trout, tuna, dorado (mahi-mahi), sailfish, tarpon, striped bass, salmon, giant trevally and marlin.
Offshore saltwater species are usually attracted to the fly by "chumming" with small baitfish, or "teasing" the fish to the boat by trolling a large hookless lure (Billfish are most often caught using this latter method).
Trout fisherman need to practice with at least an 8 weight fly rod and accurately cast the line 30–90 feet if they are going to have success—particularly in the flat areas fishing for bonefish, redfish, permit, tarpon, jacks and more.
[40] When actively fishing, the angler may want to keep the fly line lightly pressed against the rod handle with the index finger of the casting arm.
A dry fly is typically thought to represent an insect landing on, falling on (terrestrials), or emerging from, the water's surface as might a grasshopper, dragonfly, mayfly, ant, beetle, stonefly or caddisfly.
Sub-surface flies are designed to resemble a wide variety of prey including aquatic insect larvae, nymphs and pupae, baitfish, crayfish, leeches, worms, etc.
Today, artificial flies are tied with a wide variety of natural and synthetic materials (like mylar and rubber) to represent all manner of potential freshwater and saltwater fish prey to include aquatic and terrestrial insects, crustaceans, worms, baitfish, vegetation, flesh, spawn, small reptiles, amphibians, mammals and birds, etc.
