Bream
Inhabit a wide variety of lakes and large to medium sized rivers. Most abundant in backwaters, lower parts of slow-flowing rivers, brackish estuaries and warm and shallow lakes. Adults occur usually in still and slow-running waters where they travel in large shoals. Larvae and juveniles live in still water bodies, feeding on plankton. One to two years old juveniles move from backwaters to river to feed. In the absence of opportunity to leave backwaters, juveniles may adapt but have a slower growth and attain maturity at a smaller size. They also drift to brackishwater estuaries to forage when water level of flooded areas drops in lower reaches of large rivers. Foraging juveniles in brackish waters stay in lower parts of rivers to overwinter in freshwater. Feed on insects, particularly chironomids, small crustaceans, mollusks and plants. Larger specimens may feed on small fish. Juveniles feed on zooplankton.

Carp
Inhabit warm, deep, slow-flowing and still waters such as lowland rivers and large, well vegetated lakes. Hardy and tolerant of a wide variety of conditions but generally favor large water bodies with slow flowing or standing water and soft bottom sediments. Thrive in large turbid rivers. Most active at dusk and dawn. Both adults and juveniles feed on a variety of benthic organisms and plant material. Spawns along shores or in backwaters. Adults often undertake considerable spawning migration to suitable backwaters and flooded meadows. Larvae survive only in very warm water among shallow submerged vegetation. River regulation and hybridization with domesticated stocks, East Asian congeners and their hybrids have caused continuous decline of wild populations.

Catfish
Occurs mainly in quiet waters, lakes and pools but may also occur in fast flowing rivers and in rapids. Widely tolerant of extreme environmental conditions. The presence of an accessory breathing organ enables this species to breath air when very active or under very dry conditions. Remains in the muddy substrates of ponds and occasionally gulp air through the mouth. Can leave the water at night using its strong pectoral fins and spines in search of land-based food or can move into the breeding areas through very shallow pathways. A bottom feeder which occasionally feeds at the surface. Forages at night on a wide variety of prey. Feeds on insects, plankton, invertebrates and fish but also takes young birds, rotting flesh and plants. Migrates to rivers and temporary streams to spawn. Also caught with dragnets.

Eel
Inhabits all types of benthic habitats from streams to shores of large rivers and lakes. Naturally found only in water bodies connected to sea. Amphihaline species, which migrates to the depths of the Sargasso Sea to spawn. Spawning takes place in late winter and spring in the Sargasso Sea. Spawning area is reported to be about 2000 km wide. The leptocephalus larvae are brought to the coasts of Europe by the Gulf Stream in 7 to 11 months time and can last for up to 3 years. They are transformed into elvers (small eels), enter the estuaries and colonize the continental waters. Young eels spend their growing period in freshwater, males for 6-12 years, females for 9-20 years, before ending their metamorphosis. At the end of their growth period, they become sexually mature and the eels migrate to the sea where they inhabit deep waters. Recapture positions of tagged specimens in the Baltic Sea suggested unidirectional movements at a speed of about 16 km/day towards the southwestern Baltic Sea, close to the straits leading to the ocean; the recorded movements thus seem related to the eel's spawning migratory behavior. Adults do not feed during migration to sea. Gametogenesis occurs entirely during migration towards the Sargasso Sea. It occurs at temperatures ranging from 0-30°C. Is an individualist in all its stages. The 'schools' of elvers and young eels which are observed from time to time in estuaries and rivers are a mass response to outward conditions and not of active assembling. Its food includes virtually the whole aquatic fauna (freshwater as well as marine) occurring in the eel's area, augmented with animals living out of water, e.g. worms. At an age of 6-30 years, eels begin to undergo a remarkable series of changes, eyes are enlarged, head becomes pointed, skin on the back darker, while that on the belly becomes shiny and silvery. Best temperature for making eels sexually mature is 20-25°C.

Salmon
Amphihaline species, spending most of its life in freshwater. Anadromous and landlocked populations exist. Inhabits rocky runs and pools of small to large rivers and lakes. Adults inhabit cooler waters with strong to moderate flow. Young remain in freshwater for 1 to 6 years, then migrate to the ocean where they remain for 1 to 4 years before returning to freshwater. Juveniles and resident stream populations live in riffles of fast-flowing, moderately cold streams and rivers. Juveniles may live in cold lakes in northern Europe. Spawns in rivers and streams with swift flowing water and succession of riffles and pools, usually at tail of pools in gravel. Lacustrine populations move to tributaries. Maturing individuals are found on the continental plate west of Greenland. Adults return to the river of their origin to spawn, then return to sea after spawning. Juveniles feed mainly on aquatic insects, mollusks, crustaceans and fish; adults at sea feed on squids, shrimps, and fish. Larger salmon feed on fishes such as herring, alewives, smelts, capelin, small mackerel, sand lance and small cod. Adults in freshwater which are approaching the reproductive stage do not feed. Growth in freshwater is slow whereas very rapid in the sea.
