Value of species
Usually considered to be a morphologically variable species, with different morphologies reflecting adaptations to different habitats. Kottelat and Freyhoff's morphological and molecular data indicate that in fact several species are confused under the name G. gobio in the Black and Caspian Sea basins.
Atlantic Ocean, North and Baltic Sea basins, from Loire drainage eastward, eastern Great Britain and Rhône drainages, upper Danube and middle and upper Dniestr, Bug and Dniepr drainages (Black Sea basin). Eastern and southern limits not clear. Introduced to eastern and northern Italy.
Habitat: Nearly all types of riverine and lacustrine habitats with sand bottom. Known from small mountain streams, large lowland rivers and large lakes. Spawns in shallow water, over stones, sand or plant material. Often at lakes shores or in riffles.
Biology: Gregarious. Lives up to five years. Spawns for the first time at 1-3 years; most individuals spawn 1-2 years. Spawns several times in April-August at temperatures above 13°C. Eggs are released above substrate and drift with current, sinking to bottom and sticking to substrate. Larvae and juveniles are benthic and prefer detritus-rich sandy habitats and low current. Feeds on a wide variety of large benthic invertebrates.
