The aim of the experiments was to determine whether or not introduced non-native fish species have an adverse impact on the diet and trophic position of native pond fishes. The experimental set up was more or less identical in both years, the study species in 2014 being the North American centrarchid (freshwater sunfish), pumpkinseed Lepomis gibbosus, whereas in 2015 the study species was the cyprinid fish native to Continental Europe, the sunbleak Leucaspius delineatus.
