Gibel Carp - Carassius gibelio

Gibel carp is a very adaptable freshwater fish introduced from China, belongs to the family Cyprinidae. In our country first appeared in the early eighties. Gibel carp is a fish like Karasu, a large body, with silver color and no mustache like a carp.

Gibel carp loves the river with little current and lots of vegetation, is common in stagnant waters and river backwaters, which are also perfectly adapted. Gibel carp are moving across the bottom where it feeds. During the winter period are buried in the bottom substrate. It seems that in this state can survive the coldest temperatures. There is an across North Asia, and continental Europe.

Gibel carp is omnivorous which feeds on the bottom, mostly molluscs and aquatic plants. It becomes sexually mature at 3 or 4 years old. The female laid from 160 000 to 380 000 eggs. In our waters are represented more females, but males can find. They spawn with males other fish species, so that the sperm enters the egg but there is no fertilization. So can be propagated from unfertilized eggs. During the spawning gather twigs to capture the marginal vegetation at the bottom. Eggs are attached to the plant. Individuals that inhabit the lake moved to the mouth of the river to avoid a low concentration of oxygen in the water during the winter.

Bream - Abramis brama

Bream has a high, laterally flattened body, the first few years of the silver and later get back dark green, the ridge rises, separating relatively small head with small, low set mouth. A special feature of bream is very long anal fin, with 26-31 spokes, and according to some Russian sources 24 - 33 By the number of spokes, this type can be distinguished from the dark-eyed bream with 41-48 spokes from 39-46 spokes Spitzer, Nosara 20-25 spokes, and krupatice with 22-26 spokes

Bream can grow to 75 cm in length and up to 6 kg of weight, and life expectancy can be up to 20 years, although the most common bream specimens from 30 - 40 cm long and 0.5 to 1.5 kg weight. Bream usually inhabit the river, but can be found in lakes and canals where there is enough depth and enough oxygen.

During the winter, usually krtože bream in the spring, as the water warms up more, bream become active and move in search of food necessary for the ripening of sex glands and preparation for spawning. Young specimens of bream feeding on smaller representatives of the bottom fauna (snails and shells, etc..), A larger and older bream eat similar food, but she is larger.

Bream are spawning in the water with plenty of grass in April and spawning until the end of June at water temperature between 10 ° C and 14 ° C. In shallow water, up to two feet deep, bream spawn in the company of others, it related species "white fish", laying eggs on aquatic vegetation. In places protected from the wind, spawning takes place in the early morning hours, between 6 and 9 o'clock. Sexually mature male bream acquired in the third year of life, the female up to five years. The female laid of 100 000 to 580 000 pieces of roe.

Rudd - Scardinius erythrophthalmus

Rudd is a fresh, very many fish in many waters of Europe. Rudd is a fish of the family Cyprinidae. Looks very similar to the roach, but is significantly colorful - blue with purple fins, and her eyes are bright yellow with red spots, but, depending on the habitats in which he lived (standing or flowing water) colors may vary. What makes it different is they have a mouth and protruding lower lip - it feeds on the surface, unlike the roach that has reversed.

Rudd is often intersects with the bream or other larger fish of the family ciprinida - Cyprinidae, and increasingly rare, although there are isolated habitats where it has in its original form. It occurs all over Europe and the food is usually in flocks in the area (various insects), and can reach a greater weight of 2 kg. The average length of adult specimens ranges between 20 and 30 cm, and weight kapitalac over a pound and 35 to 40 cm. The must thesis known specimens were roach over two pounds, but they were mostly hybrids from crosses.

Rudd resides primarily in the great lakes, natural and artificial, but it is in the water such as ponds and excavations. It can be found in the quieter parts current water with bream. Rudd is staying close to water plants like water lilies, sedge, reed. Less exit to the open water, and during the winter in flocks back into the depths. According to the position of the mouth where it can be concluded that the roach catches insects. Catches them on the water surface and only during the day in bright sun light. Occasionally, you may notice that their dorsal fins cutting the water, leaving behind a mild ripples.

Rudd reaches sexual maturity with three or four years. Spawning in the spring between April and June. The female lays 96,000 to 232,000 eggs. The eggs are deposited on plants.
