Detail
Europe north of the Alps, from Meuse eastward to Neva drainages and Lake Ladoga; northern Black Sea basin from Danube eastward to Kuban; Caspian basin in Volga and Ural drainages. In Black Sea basin, absent south of Danube and Kuban. Not native to Great Britain, Scandinavia, Apennine and Iberian Peninsulas, Crimea, and Adriatic, Aegean and White Sea basins. Locally introduced in Rhône drainage (France) and perhaps elsewhere. Extirpated from Switzerland, recent records (in the 1990-2000s) are actually the alien species Paramisgurnus dabryanus. Population: Slowly declining. Habitat: Backwaters and side channels of lowland streams, rivers and lakes. Mostly restricted to densely vegetated habitats with slow or no current and soft, mud bottom. Spawns in dense vegetation, often in flooded meadows. Biology: Spawns for the first time at 2-3 years, at about 110 mm SL. Spawns in March-July. Males have a larger second pectoral ray and shallow vertical swellings of flanks above anal base, enlarged during spawning time. Male follows female into dense vegetation and forms a complete ring around her body, behind dorsal fin. Sticky eggs are released into vegetation. Larvae move to bottom and hide in mud. Larvae have large external gill filaments, reabsorbed after 10-12 days. Adults nocturnal, burrows into mud to hide during day and, especially in shallow habitats, during dry periods and strong frosts. Usually burrows 200-300 mm deep, occasionally down to 700 mm during dry periods. Able to survive in habitats with low oxygen concentrations by cutaneous and intestinal respiration. Frequently swallows air, oxygen being absorbed through the walls of the gut. Feeds on benthic invertebrates. Swims slowly above bottom and dig for invertebrates, which are localized by olfaction.
