Czech Nymphs & Gammarus

20 from 29 Products displayed

"Czech Nymphing" has become quite popular with fly-fishermen for some time now, although it is highly controversial. Originally, the Czech nymphs were imitations of trichoptera (without casing), often of the predatory species Hydropsychidae and Rhyacophilidae.
Most of our Czech nymphs are weighted and tier on curved hooks (Scud). These nymphs are rather thin, to ensure rapid sinking.
In this category of flies you will also find different imitations of amphipods (Gammaridae). These small crustaceans live in freshwater lakes and rivers. Most individuals live on the seabed to a depth of two metres. The purity of the water is not as important for the growth of these animals as the high oxygen content. The Gammarus can play an important role in the food chain of our finned friends.
Our Gammarus nymphs (also known as Scuds or Shrimps) sink more or less quickly, depending on the construction method.
