Krąp – (Blicca bjoerkna) – Carp bream

Krąp – (Blicca bjoerkna) – Carp bream (L., 1758)), ryba z rodziny karpiowatych (Cyprinidae), jedyny przedstawiciel rodzaju Blicca, często mylona z leszczem. Różni się jednak od niego mniejszą ilością promieni miękkich w płetwach: grzbietowej i odbytowej oraz mniejszą ilością łusek w linii bocznej.
Dorasta przeciętnie do 30 cm (maks. 36 cm) i 0,5 kg wagi (maks. 1 kg). Żywi się bezkręgowcami, larwami owadów i roślinami. Często uważana za szkodnika. Z tego powodu nie posiada ani wymiaru ani okresu ochronnego zato jest lubiany przez zawodników startujących w zawodach wędkarskich za pobieranie przynęty oraz robienie sporej wagi. Występuje w wodach całej Europy. Preferuje nizinne, wolno płynące rzeki lub jeziora. Wymiar ochronny brak

Krąp – (Blicca bjoerkna) – Carp bream


 

The carp bream (Abramis brama) is a species of fresh-water fish belonging to the family Cyprinidae, to which about 1,500 species belong.The bream’s home range is in Europe north of the Alps and Pyrenees, as well as in the Balkans. It is also found as far east as the Caspian Sea, the Black Sea, and the Aral Sea.The carp bream is usually 30 to 55 centimeters (12 to 20 inches) long, though some specimens have been as long as 75 cm (30 in.), and weighed two to four kilograms (four to ni zpwne pounds).
It has a laterally flattened and high-backed body and a slightly inferior mouth. The fish is a silvery gray color, though older fish can be bronze-colored especially in clear waters. The fins are grayish to black and never colored.t can easily be confused with silver bream (Blicca bjoerkna), in particular at the younger stages (see picture). The most reliable method is counting the scales in a straight line from the first ray of the backfin to the lateral line.

White bream has less than ten scales, carp bream 11 or more. At the adult stage the reddish implant of the pectoral fin of the Silver Bream is a very clear mark. Like all cyprinidae carp bream can easily hybridize with other species. Using artificial reproduction carp breams have been crossed with ruffe to create an attractive fish for angling.It lives in schools near the bottom. At night carp bream can feed close to the shore and in clear waters with sandy bottoms the feeding pits can be seen during daytime. The fish’s protactile mouth helps it dig for chironomidae larvae, tubificidae, bivalves, and gastropods. The carp bream eats water plants and plankton as well. In very turbid waters bream can occur in large numbers which can result in a shortage of bottom feeds like chironomidae.

The carp bream is then forced to start filter feeding with its gill rakers with Daphnia as the main prey. As the fish grows the gill rakers grow to far apart to catch its prey and the bream will not grow bigger then 40 cm. If a carp bream is malnourished it can develop a so-called knife back, the formation of a very sharp edge along its back.By : Wikipedia
