Flood duration determines the reproduction success of fish in artificial oxbows in a floodplain of a potamal river

Original language description

Fish reproduction was studied in six man-made water bodies (borrow pits) adjacent to the channelised Dyje River (Danube basin) over five seasons. Terrestrial vegetation provided spawning and nursery habitats when inundated by raised water levels in the borrow pits (hereafter referred to as floods?). The diversity of 0+ fish and the density of 0+ cyprinids were positively correlated with flood duration in previous months. The density of 0+ Perca fluviatilis was independent of the flood duration. The density of spawners and predators did not influence the diversity of 0+ fish and the density of 0+ cyprinids. Receding flood and associated lack of shelters resulted in decreasing density of 0+ cyprinids. Prolonged floods facilitated the survival of 0+ fishand resulted in high 1+ cyprinid density in the following season. Specific hydromorphological conditions are necessary to enable successful spawning and provide shelters for 0+ fish in artificial water bodies.
