摘要:
We compared post- and pre-introduction data for the upper Pilica River and its tributaries to investigate the impact of introduced non-native brown trout on native fish communities. Extirpations of species were recorded. More changes concerned differences in abundance and distribution in the investigated rivers rather than extirpations. Human stressors (pollution, regulation) obviously helped the invasion of trout. Repeated introduction to one tributary of the Pilica enabled brown trout to survive for 10 years, despite the presence of pike and the recent appearance of domestic pollution.
