What are Czech nymphs?

As the name suggests, Czech nymphs are a kind of nymph pattern first made popular by fly fishers in the Czech Republic. They've become popular across the world and are regarded as one of the best patterns to use when nymphing for trout and grayling on fast flowing rivers and streams.

How do you fish Czech nymphs?

These heavily weighted flies are fished using a method known as Czech nymphing. This is a fly-line-less method in which you use a long tapered leader instead of a fly line and rely on the weight of the flies to let you log them a short distance upstream.

The flies are then guided back downstream by raising the rod high and moving it along at the same speed as the current. A brightly coloured inline strike indicator is used to detect the bite, and you strike whenever it stops or dips.

What hooks are Czech nymphs tied on?

Czech nymphs have a curved profile so are always tied on curved hooks. You can use a standard buzzer or grub hook if you like, but there are also some really nice specialist Czech nymph hooks available which can give your flies a really great look.

How do you weight Czech nymphs?

Most Czech nymphs have an underbody made from either lead or lead-free wire or tape, or more rarely, they have a bead hidden within the body. Adhesive backed lead foil or tape tends to be the most popular material for adding weight because it's less bulky and allows you to build up a natural looking taper for your fly.
