Detail
The systematics of sand gudgeons in Danube is not resolved and several species seem to be confused under the name R. kesslerii. Dniestr and tributaries of lower and middle Danube drainages (Black Sea basin); upper Vistula drainage in Poland (Baltic basin). Abundant species, but expected to decline in the future. Fast-flowing piedmont rivers with large areas of sand bottom. Spawns in shallow water over gravel, sand or plant material in fast-flowing water. Gregarious. Lives up to five years. Spawns for the first time at 2-3 years. Most fish spawn 1-2 years, from late May-early June until late August-September. Eggs are released in successive portions. To spawn, both sexes move to surface or open water. Eggs drift with current, sink to bottom and stick to substrate. Juveniles and adults are active during day. Feeds on a variety of benthic invertebrates, usually catching drifting food organisms.
