Abstract

<abstract abstract-type="main" id="jfb12427-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p id="jfb12427-para-0001">Higher biomass especially of some aquatic macrophyte species offered a higher density of phytophilous zoobenthos, but did not increase the proportion of non‐planktonic to planktonic prey in young‐of‐the‐year perch <italic>Perca fluviatilis</italic>. Both abundance and biomass of non‐planktonic prey dominated over planktonic prey in the pond with lower biomass of aquatic macrophytes and lower food. Survival of <italic>P. fluviatilis</italic> was lower (20%) in the pond with lower food than in the other pond (34%), however, specific growth rate (1·3% day⁻¹) and final Fulton's condition factor of <italic>P. fluviatilis</italic> were similar in both ponds.</p> </abstract>
