在德国包岑水库，作为生物操纵工具的欧洲鳗鲡（Anguillaanguilla）具有强烈的食鱼性，每胃含鱼量为2.2 ± 1.3（平均值±标准差）。 0+年河鲈是最常见的猎物项目（54%），和0+年梭鲈桑德lucioperca是最重要的猎物生物量（45%）。
Strong piscivory by eels Anguilla anguilla, which were regularly stocked in the Bautzen Reservoir, Germany, as a biomanipulation tool, was observed, with the number of fishes per stomach containing fish being 2· 2 ± 1·3 (mean ± s.d.). The 0+ year perch Perca fluviatilis was the most frequent prey item (54%), and 0+ year pikeperch Sander lucioperca was the most important prey in terms of biomass (45%).
