Czech Nymphing Patterns for fly fishing

czechs fly fishing

Are you in search of the best Czech nymphing patterns to catch more fish? Try the Czech nymphing and you will be amazed at what you get. The development of mayflies, flies, mosquitoes and other insects occurs at the bottom of rivers, under rocks, among underwater plants and in sediments.

Take a look at the bottom of the river in shallow water. Flip some rocks, take out a sunken branch. You will see a true abundance of life. Among other things, you will discover various nymphs and larvae, as well as an animal about 1 cm long, the scud, a freshwater shrimp.

Most of the animals you find below the surface of the water are an indispensable part of the menu of what is our main goal and passion: the trout we try to catch with our flies.

After a brief look at life beneath the water’s surface, it’s not hard to see why nymph fishing is successful.

When we catch nymphs in flowing waters, we fly fish into the water column, often near or along the bottom, which means exactly where most of the fish food is and where the fish feed easily. When fishing with nymphs, we almost always imitate scud (freshwater shrimp), as well as flies, midges and midges.

For many anglers, nymph fishing will never be the same as classic dry fly fishing and its beauty. But thanks to its effectiveness, this method is indispensable for the modern fly fisherman and will bring many unforgettable experiences to those who master nymph fishing.

What is Czech nymphing?

Fishing for Czech nymph or Czech nymphing technique is a special method of fly and nymph fishing that has been developed in the regions of Central and Eastern Europe. The original Polish nymph was adopted by Czech fishermen in the 1980s. In particular, the main Czech competitors have experimented with this new method, developed it and brought it almost to perfection.

The principle of czech nymphing is fishing at a short distance, practically under the tip of the rod, which is kept at a safe distance.

The fly fishing line hangs under the tip of the rod and often its end does not even touch the surface of the water. Two or three nymph flies of various weights are used. Some of the classic Czech nymphs are called Bobesh, the original Czech name needs no translation as the technique spread rapidly and is now widely used.

But other types of flies are also used. Czech nymphs are heavy flies attached to gammarus hooks, which mimic freshwater shrimp or river insect larvae and are the main food of trout. Imitative and colorful prints are used, mainly in sizes 8 to 16.

The Czech nymph is a fairly easy fly to tie. It features a rounded (bent) hook, which is weighted with lead wire. The body is created with materials of natural or synthetic origin. Another typical feature of a Czech nymph is the back, made of latex or material with similar characteristics. Monofilament or colored thread is used to segment the fly. A true Czech nymph is always tied up very skinny, so she sinks very quickly to the bottom.

Czech nymph patterns.


The basic method of fishing with the Czech nymph is the so-called short nymph (or spiral nymph). When we use this method, we fish practically under the tip of the rod, often without even using the line which in most situations does not touch the surface of the water. After casting upstream, let the flies gradually sink to the bottom and follow their downward movement with the tip of the rod.

Our barrel arm is stretched out in front of us all the time. When the flies float where we are, they rise from the bottom with an upward motion of the shaft and launch again. To be successful with the short nymph method, we must maintain constant contact with the flies. Catching a fish is indicated by any inconspicuous movement of the rat’s head or tail upstream or sideways, or even a brief hesitation of the flies as they move through the water. When we do not maintain contact with flies, the chance of detecting a catch is greatly reduced. There are several things to do to maintain contact with flies.

Things to do

First, the flies must be properly “guided” through the water and the rod and line must follow their movement, trying to keep the leader taut at all times. Another important factor is the length of the leader. When it is short, it is easier to maintain contact with flies. Last but not least, it is very important to have a fly with the right weight. Maintaining contact with heavier flies is much easier than with lighter flies (however, lighter flies behave more naturally in the water).

Czech nymphs are not to be used only “short”, and similar success can be achieved using the “long” method, when the flies are thrown higher and we let the line float to the surface. Strikes are identified by movements or hesitations at the tip of the line. Depending on the conditions, we can combine these short and long methods and fish upstream, downstream and across the stream.

Fly fishing equipment.

A universal and generally recommended configuration for Czech nymph fishing is a 275 cm long rod. We use a normal conical line with the same numbering as the rod. Recently there has been a trend towards the use of auctions n. 3 or n. 2 lighter. It is important to use a rod that is as light as possible, because when we use the Czech nymph technique (fishing with outstretched arm, cast frequently) we feel every extra gram. The garment is made up of three sections of monofilament (no need for taper) from 0.12 to 0.18 in diameter.

The length of the leader should not exceed the length of the barrel. A useful part of the system for the Czech nymph is a bite indicator. Since many clicks are identified by line movements, it is always helpful for the end of the line to be clearly visible. For this, so-called speed connectors in different colors are very popular and are also a good device for connecting the line and the leader.

The last important equipment of the Czech fisherman is the wading pants. Since we are looking for fish at close range, it is often necessary to walk to places where we would simply resort to other methods. Other parts of the equipment do not differ from those used with other techniques.

Fishing tactics of the Czech nymph will always differ depending on the conditions, there are no perfect tactics. In any case, it is important to take into account several conditions that must be met to be successful:

Analysis of where to fish

With a Czech nymph, we usually fish in low and deep currents and on the boundary lines between these waters and in eddies and ponds calm down. We look for places, where there are deep places (pools), in these there are often fish. We will also be successful in deep pools between two streams and near clusters of aquatic plants such as water buttercups.

When to fish

The technique is effective practically all season (compared to other methods). The technique is much more effective in the quantity and sometimes the quality of the catches. In most cases, when we cannot see any fish activity on the surface of the water, it is worth using the Czech nymph method.

How to catch the Czech nymph?

We fish at close range, often only up to a certain point. That distance is slightly more than the length of our rod. We let the flies move freely, only during the final stage do we often achieve success. Then we let the flies soar from the bottom up. The right fly weight is important. The flies must be heavy enough to sink to the required depth. But in return they must not weigh too much, so that they do not tend to get entangled on the bottom. And even when they are overweight they cannot be carried by the water.

The weighting of the flies should be flexibly adapted to the depth and speed of the current. When actually fishing, flies should be as close to the bottom as possible where we expect a bite. As for the short distance we are fishing, we must be careful not to scare the fish.

When fishing in clear or shallow water, the efficiency of our fishing can be greatly increased.

Which fly?

there is no general rule that determines the most effective pattern of the Czech nymph. When we don’t know which flies it will respond to, we placed three patterns of flies on the garment in different color combinations and tested the effectiveness of the individual patterns.

Usually a natural motif is tied as the fly tip or first dropper. And a “wilder” motif as the second dropper. The deeper the water, the larger the fish we expect. and the larger the fly patterns we can use. For brown trout fishing, imitation models are more suitable. For rainbow trout we use various color combinations alongside natural models. Which have nothing in common with natural food imitations.

The Czech’s flies

The basic model for fishing for the Czech nymph is a fly. In Czech Its called Bobeš (read bobesh = Czech nymph). It is a weighted fly tied to a curved hook. The Czech nymph mimics freshwater shields, cased caddis larvae or is made up of absolutely fantastic color combinations.

A true Czech nymph needs to be slender. It need to sink as close to the bottom as possible during her short run through the water. The size of the flies varies according to the fishing conditions (water depth, clarity, current speed, fish size, etc.). The most used sizes for European waters are # 10 and # 12. When the nymph is fishing in large rivers or waiting for a large fish to be hit, we often use flies up to size 6.

We can match fly types, patterns, sizes and colors to our heart’s content with no guaranteed or optimal match. When we know which flies are catching the fish, we can catch three identical patterns. In one situation, when we don’t know the river or don’t know the fish appetite, we just have to experiment. And in that case it gives us an advantage, when we tie three different flies in different colors. and dimensions
