Fish species from River Klokot
Brown trout (Salmo trutta fario)
The freshwater fish is one of the most popular salmons worldwide. It is marked especially by its relatively big head and mouth, its teeth are very sharp. While its body colour depends on its surroundings, its back is mainly olive-brown, yellowish-green sides. A special characteristic are its red and black spots all over the body. The scales are small and round.
The brown trout lives in mountain rivers and streams with cold and clean water, low temperature changes and a high oxygen level. It is staying near the river ground in those river sections with big vortexes.
Brown trouts reach their sexual maturity in their third year from a length of 25 cm.
Their nutrition consists mainly of grubs and other invertebrate water animals as well as small fish. Its can become 15 years old, reaching a length till 1 metre and a weight of up to 15 kg, depending on the food supply and water quality.
After two years already, the brown trout can reach a weight of up to 1.5 kg. Some caught examples reached a length of 124 cm and a weight of 25.5 kg.
Brown trouts can be found in cold mountain rivers of Western and Middle Europe till the Balkans and the Caucasus. Hunting this fish demands a lot of experience and patience which makes it even more interesting.
The best period for angling is in the morning and early evening in the warmer months, and during the whole day during the other seasons or on a cloudy day, respectively after a summer rain. Its meat is considered as particularly tasty.
Grayling (Thymallus thymallus)
The grayling’s body is more slender and longer then of the trout. Due to its smaller mouth, the angler has to use smaller baits, too. The body colour is metal-grey, the back greenish with round black spots, the sides are yellowish, the belly white. Caught graylings had weights of 2,5 kg and more. Graylings are reproducing from March to May. Main food source are grubs, small water animals, snails and fly which it hunts in all water levels. Besides that, the grayling is eating small insects and fish.
The grayling is a very fast hunter of flies which are falling in the water, or can just touching the surface during their flight. In contrast to other fish species, the grayling does not eat them immediately but spits it out if the taste is not suitable. Therefore, the angler has to act very carefully, even after the fish has snapped for the fly. Also a grayling, once it has escaped from the hook, could not be tricked another time at the same place.
While waiting for a grayling, it is extremely important to hide well. The best chances are in case of a light wind moving the water surface and blurring the sight to the angler. Like for the brown trout, best time for angling is in spring, autumn or during summer in the morning / early evening, respectively on cloudy or rainy days.
For the grayling can be used the following baits: wet or dry fly, nymphs, grubs, worms or caddis fly larvae but mostly are used flies. Nymphs are rather used for deeper water levels. The moves of the nymphs are stimulating the grayling’s hunter’s instinct.
Danube salmon (Hucho hucho)
With a length of up to 1.5 m and a weight of up to 50 kg, this fish is one of the biggest salmon species and the biggest of the region. The Danube salmon is living in fast, cold and oxygen-rich rivers.
The body is longish and covered with black spots. The colour of the trunk is adapting to the environment, the back is dark-brown to yellowish or bluish-grey, the belly white-silver to dirty white. During the spawning period the colour is changing to copper-pink. The head is big, massive and longish, including the huge operculum. The strongly prominent teeth have a hook-shape, the scales are very small. Thanks to its strong tail fins, the Danube Salmon is an excellent swimmer.
In the average, this species reaches a length of 60-120 cm and a weight of 10-12 kg. Females become sexually mature in their fourth year, males in the third. From February till May, the female is laying 15,000 und 25,000 eggs on the pebbly ground. After 35 days, the young fish are hatching with temperatures of 8-10oC and are nourishing themselves with diverse invertebrate animals, before changing to fish in their second year.
