Habitat and Way of Life
Habitat of the Ide or Orfe
The Ide or Orfe is found in the lower and middle parts of rivers, as well as lakes and ponds throughout Europe, except for southern regions such as Spain, Italy, and Portugal. It is also present in Asia, reaching as far as the Ural Mountains. This fish has been introduced in Great Britain, the USA, and New Zealand, although its presence in Switzerland is uncertain. The Ide or Orfe is a gregarious fish, forming schools of varying sizes during its younger years and becoming more solitary as it matures. It occupies the entire water column, from the bottom to the surface.
Diet
The Ide or Orfe exhibits an omnivorous diet that evolves throughout its life. While young, it mainly feeds on vegetation, benthic invertebrates, insects, mollusks, and crustaceans. As it grows, it becomes carnivorous, preying on fry and small fish. This fish’s unique feeding behavior allows it to be caught using various fishing techniques, such as bottom fishing with baits like maggots or worms, as well as surface fishing with fly or float.
Reproduction
The spawning season for the Ide or Orfe (Leuciscus idus) occurs in spring, typically between April and June. Sexually mature adults migrate to rivers and streams, seeking shallow areas with sandy or gravelly bottoms, rich in aquatic vegetation. In lakes and ponds, spawning takes place in the shallower zones and coves. Females lay between 40,000 to 250,000 eggs, which adhere to gravel and aquatic vegetation. The incubation period lasts 15 to 21 days, and the fry spend their first year in the calmest areas of water bodies.
Significance of the Ide or Orfe (Leuciscus idus) for Fishing
For anglers, the primary significance of the Ide or Orfe lies in its sporting nature. As a robust member of the dace family and a close relative to the chub, it puts up a fierce fight until the very end. Additionally, this fish holds significant value in the realm of aquarium keeping. It is easy to raise, boasts a long lifespan, and exhibits non-aggressive behavior towards smaller fish (unless they are too tiny, in which case they may be seen as tempting appetizers).
Fishing Techniques for the Ide or Orfe
The fishing techniques employed to catch the Ide or Orfe (Leuciscus idus) are similar to those used for roach. It can be caught using a float fishing technique near the bottom, where it responds particularly well to bait such as maggots or worms, especially when targeting larger specimens.
