Perch live in schools, often mixing with other species of fish, usually in the top 50 metres of water. Spawning takes place in April, the very sticky eggs being produced in bands. Females twine these bands around submerged vegetation or among rocks while the males follow her and fertilise the eggs. The young fish hatch after about three weeks and remain amongst the egg bands until the yoke sac is exhausted. They then venture into more open water and feed on planktonic animals. As they grow they begin to shoal together close to the bank. Males mature when they reach the length of 7 – 8 cm, females when they are 10 cm.

Occurs in lakes, pools, backwaters, and runs of medium to large rivers. Prefers large, shallow lakes with high turbidity . Feeds at night, mainly on insects and fishes but feeds on crayfish, snails, frogs, mudpuppies, and small mammals when fish and insects are scarce . Although not widely farmed commercially for consumption, large numbers are hatched and raised for stocking lakes for game fishing . Utilized fresh or frozen; eaten pan-fried, broiled, microwaved and baked .
Chondrostoma nasus (Linnaeus, 1758) (Sneep)
Gregarious. Occurs in fairly shallow water with fast current, often beside the swirls created by piles of bridges or rocks . Inhabits moderate to fast-flowing large to medium sized rivers with rock or gravel bottom. Larva...

Gregarious. Occurs in fairly shallow water with fast current, often beside the swirls created by piles of bridges or rocks . Inhabits moderate to fast-flowing large to medium sized rivers with rock or gravel bottom. Larvae occur below surface and feeding larvae inhabit along shores. Early juveniles live on the bottom in very shallow shoreline habitats. When growing, they move from the shore for faster-flowing waters. Juveniles overwinter in backwaters or in cavities along shores. During winter, adults form dense swarms in lower parts of rivers. Larvae and early juveniles prey on small invertebrates while larger juveniles and adults feed on benthic diatoms and detritus. Migrates some tens of km to spawning sites, which are often located in tributaries. Spawns in fast flowing water on shallow gravel beds often in small tributaries . Reported to migrate upstream and enters small tributaries for spawning in shallow water on gravel . Its flesh is good but bony . Locally threatened by damming, destruction of spawning sites and pollution. In drainages where it is introduced, this species outcompetes and eliminates Parachondrostoma toxostoma in Rhône and Protochondrostoma genei in Soca .

Inhabits a wide variety of still water bodies and lowland rivers, usually associated with submerged vegetation or regular flooding. Can strongly tolerate low oxygen concentrations and pollution . Lake dwelling individuals move into river mouths to avoid low oxygen water in winter . Feeding larvae and juveniles occur in high-complexity habitats as reed belts. Feeds on plankton, benthic invertebrates, plant material and detritus. Spawns in shallow, warm shores on submerged vegetation . Able to reproduce from unfertilized eggs . Life span reaches up to about 10 years . Eastern European or wild form of the goldfish .
Tinca tinca (Linnaeus, 1758) (Doctor-fish)
Typically found in shallow, densely vegetated lakes and backwaters. Often overwinters buried in mud. Larvae and juveniles confined to dense vegetation . Adults inhabit warm lakes and pools with weed and mud bottom. Tol...

Typically found in shallow, densely vegetated lakes and backwaters. Often overwinters buried in mud. Larvae and juveniles confined to dense vegetation . Adults inhabit warm lakes and pools with weed and mud bottom. Tolerates low oxygen saturations . Feeds on detritus, benthic animals and plant materials. Adult often prey mainly on molluscs. Spawns among dense vegetation in still water . Used as a fodder fish for bass . Utilized fresh and frozen; eaten pan-fried, broiled, and baked . Popular with amateur sport fishers. Its flesh is highly esteemed . Locally under threat due to river engineering . Reported to reach a maximum length of 84 cm TL .
