Czech Nymphing - Fly Fishing Flies Selection

Czech Nymph Fly Selection

There is one essential thing that the fly fisherman will need when czech nymphing, that is heavy flies! Usually using a team of 3 flies on droppers with the point fly being the heaviest fly.

Cased Caddis - The Prey

Caddis Flies are widespread across Europe wherever water is available, either static or running. However, the adult is a strong flyer and can move some distance from ponds, streams and rivers, especially as it is attracted to light.  However it is the larvae form that is a key part of the diet for fish such as trout. The larvae which make a "case" in which to live using small stones, sand, pieces of leaves and all glued together with a silk lining inside. The silk is spun with a secretion from labial glands (around the mouth) like moth larvae. When full-grown the larva pupates in the case which stops being mobile and may be glued down to a rock. 

The cased forms feed on vegetation whilst the caseless forms tend to be either carnivorous or detritivores. The predatory ones are those free living. The web-spinning, caseless larvae may create a silk tube in which to live whilst those in moving water spin the web between stones. This web may trap small invertebrates drifting with the current. This invertebrate drift, as it is known, is an abundant source of food as the current constantly dislodges animals living on the bottom of streams and rivers. Many of these caseless caddis larvae are associated with particular speeds of flow. However, much of what they catch will just be drifting detritus and other organic particulate matter on which the larva will feed (hence detritivore). Some particulate matter will be drifting plankton. Those larvae in especially fast flowing water, e.g. Hydropsyche, will have toughened upper parts to the thoracic segments (thickened external skeleton is refered to as being sclerotised). The larvae have their abdomens safely in the silk tube but the front section of the body protruding into the current. This sclerotisation may be an adaptation to protect them from small stones and other material hitting them.

It is this caddis that is one of our primary fishing imitations when czech nymphing. Below are different imitations that can be used in descending weight order, with the heavyweights of the czech nymphing world described first.

Czech Bottle Fly - Super Heavyweight Flies

Czech bottle nymphs are the "bruisers" of the fly fishing world. Designed to hold botom in the fastest of waters a czech bottle nymph is a uniquely designed fishing fly.  The Bottle Fly is a complete fly, designed in the shape of a bottle and is available in 2.2gm, 3.4gm, 4.4gm and even 5.5gm weights. The fly is manufactured from pre-made moulds which are tied very simply, the bottle is rolled in glue and sand is rolled onto the fly, a hackle is then simply tied to the front. The finished fly is identical to a caddis in its nest described above. The beauty of this fly being that it will hold bottom or take a team of flies to the bottom of the fastest of rivers. We use this for sea trout frequently as it can be used to hold a snake fly low in the fastest of waters!

Traditional Czech Nymphs - Heavy Flies

These are the more "traditional" czech nymphs used around the world. These are still a heavy fly, often tungsten weighted to keep the fly low in the water.  Czech nymphs are available in a range of colours, from pea green to cream and red, from hares ear and amber to sparkle and orange. They key with these colours is actually that the czech nymphing technique is forcing the trout to make a rapid decision, fast water with stimulating colours is often deadly.

A technique I frequently use is to use a heavy fly, often a bottle fly on the point with a natural colours czech nymph on one dropper and a nymphs with colours on the second dropper. Using this technique you can see what the trout are eating before focussing on specific colours.

Goldhead / Beadhead Flies

These are the "lightweight flies" used in czech nymphing. The Goldhead or Beadhead fly has a small bead which gives it weight, ideal in slower rivers when czech nymphing and frequently used as an alternative dropper.

Standard Nymphs

Do not forget to truly work a team of droppers, there is nothing to stop the fly fisherman using a standard caddis, nymph, stonefly or other fly on a dropper when czech nymhing, the key is that it needs to be kept low and close to the river bottom.

Green Energy In Emerging Economies: Renewable Investment, Capacity Growth, And Future Outlook

Global economic and energy demand growth will be concentrated in developing economies, so there is much potential for the role of renewable energies in emerging markets to expand over the next two decades. Although conventional forms of energy will still dominate the energy mix, the expansion of power-generating capacity in emerging markets will at least partly be supplied by growth in wind, solar, bio and hydropower.

The BRIC – Brazil, Russia, India and China - countries and other emerging markets are facing the twin challenges of promoting economic growth while mitigating the environmental impact of their growth strategies.

While there is criticism that countries such as India and China have balked from making more firm commitments to cutting their GHG emissions, both these countries nevertheless have prioritized renewable energy development as part of their strategy to reduce the carbon intensity of their respective economies per unit of GDP.

Therefore, developing economies led by the BRIC countries are playing an increasingly crucial role, not just in the global economic order, but also in the climate change debate and in the dynamics of global energy supply and demand.

Key findings

China will be one of the major markets for wind power over the next two decades. China's National Energy Administration stated that the country aims to more than double its wind power capacity to 30GW by 2020. China will reportedly invest at least $150bn to achieve the 30GW target by 2010.

By 2030, non-OECD economies will account for 59% of global energy consumption, a marked increase from 49.8% in 2006. Also by 2030, non-OECD economies will be emitting 25.8bn mt of carbon dioxide, or 64% of total emissions.

Brazil has huge potential for renewable energy through the burning of bagasse – a waste product from sugarcane production - to generate onsite heat and power. In
2009, it is estimated that 8,892MW of power will be produced by sugar cane with 3,600MW available to the market.

Incentive schemes will be crucial for the development of renewable energy sector over the next two decades. The report includes a detailed look at the many policies being promoted by the emerging economies, with a special emphasis on India.

Renewable energy policies differ greatly among the smaller emerging economies, ranging from the promotion of solar power in the Czech Republic to the concentration on geothermal power by the government of Indonesia.

Use this report to...
• Achieve a quick and comprehensive understanding of the renewable energy sector in the major emerging economies.
• Realize up-to-date competitive intelligence through an extensive review of the different forms of renewable energy and the different rates of development depending on the country.
• Assess the policy goals of the emerging economies regarding renewable energy and how these are driving capacity expansion.
• Identify which forms of renewable energy and which markets have the greatest growth potential for renewable energy.
• Identify the main drivers and resistors to growth for all the main renewable energy sources in each of the major emerging economies.

Explore issues including...

Environmental requirements: - By 2006, non-OECD economies had exceeded the OECD in energy related carbon dioxide emissions. Meanwhile, BRIC countries, especially China and India, will play a major role in emissions growth over the next two decades by virtue of the fact that in each case economic growth and energy demand expansion will be robust. On the back of this, emerging economies are coming under increasing international pressure to cut emissions and invest in renewable sources.

Legislative issues: - As China has become a leading emitter of GHGs, its government has also decided to facilitate the growth of cleaner renewable energy sources to help fuel the country's economic expansion. This has resulted in the country pledging to install almost 350GW of renewable capacity by 2030. Faced by similar problems, many of the leading emerging economies are also adopting comprehensive national policies to promote renewable energy.

Government support for renewable energy: - The cost of renewable energy remains above that for fossil-fuelled generation technologies. Therefore the sector has required substantial government support in the emerging economies in order to stimulate development. This includes the implementation of generous fixed tariffs for electricity generated and other support schemes such as tax incentives.

Future growth: - Rapid economic and energy consumption growth in non-OECD countries will need to be fed by expanded power generation. Meanwhile, a shift in an overall policy towards environmental issues is occurring at the same time. Together these two issues will combine to drive substantial renewable energy investment in the developing world up to 2030.
