| Impact Description | Introduced Osmerus eperlanus in a Norwegian lake likely contributed to an increased abundance of small prey fish for brown trout, whose diet shifted earlier to piscivory with a more pelagic focus and thus benefited from increased growth rate. Ultimately, European smelt shifted the food web and fish community in the lakes from a littoral to a more pelagic base |
