✦ Synopsis

The bream (Abramis brama L .) population of Tjeukemeer was studied for three successive years . The growth, condition, gonad development, diet and feeding conditions of the fish are described . Food competition for two years with the then abundant young planktivorous smelt (Osmerus eperlanus) and perch (Perca fluviatilis) resulted in a decreased growth rate, condition and gonad development of the larger bream . The biomass of chironomids was too small in relation to that of the zooplankton to be important for the bream population, although they were eaten more efficiently .
