Perhoja

Perhoja are artificial fishing lures used in fly fishing. They are tied on a fishing hook and designed to imitate insects, larvae, or small aquatic prey. By presenting a realistic movement and profile, perhoja aim to entice fish to strike.

Construction and materials: Perhoja typically consist of a hook, thread, and a body formed from materials such as feathers, fur, hair, or synthetic fibers. Additional features may include a tail, wings, hackle, and head, assembled with glue or varnish to preserve shape. Colors and patterns are chosen to match water conditions, weather, and target species.

Types and techniques: Perhoja are categorized by whether they float, sink, or suspend. Dry flies remain on the water surface; wet flies and nymphs sink and imitate subsurface prey. Streamers imitate small fish or amphibians and are often larger. Anglers select patterns for specific insects or environments and may tie their own or purchase commercial flies.

Use and context: Perhoja are central to fly fishing in freshwater systems for species such as trout and grayling, and are also used in some saltwater settings. Fly tying, the craft of making perhoja, is practiced by hobbyists and professionals alike and supports a significant fly-fishing gear industry. Environmental and local regulations may influence acceptable forms and catch limits.

Origin: The practice originated in the 19th century in Europe and North America as part of the broader development of fly fishing. In Finland, perhoja are a central element of perhokalastus, the Finnish form of fly fishing.
