| Description
| - Predation on non-native cyprinid, Pseudorasbora parva, was reported during annual study in a small connecting canal about 40 km south of Brno, Czech Republic. Two cyprinid fish species (Pseudorasbora parva, and Rutilus rutilus) were identified in the diet of 23 piscivores belonging to three native fishes (Perca fluviatilis, Sander lucioperca, and Esox lucius). In environment, relative abundance of prey fishes changed seasonally dominated by topmouth gudgeon in spring and continuously increasing roach incidence. In contrast, topmouth gudgeon was found to be more sized-available prey (P < 0.001) and was the most dominant prey species in the diet of all piscivorous fishes the whole season throughout. Strong piscivory towards this alien might be beneficial for its eradication or control to support ecological integrity in natural and modified seminatural habitats. (en)
- Během roční studie rybničních stok, lokalizovaných 40km jižně od Brna byl zdokumentován predační tlak na nepůvodního cyprinida, střevličku východní (Pseudorasbora parva). V potravě 23ks dravých ryb (Perca fluviatilis, Sander lucioperca a Esox lucius) byly zaznamenány dva druhy rybí kořisti, střevlička východní (Pseudorasbora parva) a plotice obecná (Rutilus rutilus). V potravní nabídce byl zřetelný sezonní charakter, s dominancí střevličky v jarním období a postupným nárůstem abundance plotice. Po celé sledované období představovala střevlička velikostně dostupnější kořist a v potravě tvořila zcela dominantní potravní složku. Pozorovaný silný predační tlak na tento nepůvodní druh může být výhodně využit pro jeho eradikaci či limitaci v přírodních či modifikovaných habitatech. (cs)
