Docksides as winter habitats of chub and pikeperch in

Popis výsledku v původním jazyce

To test whether docksides in channelised rivers can provide winter habitats for fi sh, 19 specimens of chub and 8 specimens of pikeperch were radio-tracked for more than 12 months. Locations of fi sh were obtained weekly along a 40-km long stretch of theElbe River in the Czech Republic. Occurrence of chub in docksides was associated with a decrease in water temperature, whilst pikeperch occurrences within docksides were distributed randomly across all seasons. Fish entrance into docksides was not signifi cantly infl uenced by the fl ow regime of the river. Both species displayed size-dependent spatial segregation in the adjacent river stretch. Our results showed that the docksides were not permanently occupied by pikeperch or chub across seasons. We suggest that docksides enhance habitat diversity in channelised rivers.
