Research output: Thesisinternal PhD, WU


<p>IJsselmeer, a eutrophic, shallow lake (mean depth 4 m) of 180,000 ha, is heavily exploited by a fishery that catches dfl 11 million worth of eel <em>Anguilla anguilla</em> , perch <em>Perca fluviatilis</em> , pikeperch <em>Stizostedion lucioperca</em> and of the small zooplanktivorous smelt <em>Osmerus eperlanus,</em> the main prey for perch and pikeperch and for the piscivorous birds of IJsselmeer. The population of cormorant <em>Phalacrocorax carbo</em> affects the fisheries through its predation on perch and pikeperch, whereas black tern <em>Chlidonias niger</em> and black-headed gull <em>Larus ridibundus</em> are affected by the availability of smelt in IJsselmeer. The spatial distribution of prey fish and piscivorous birds was described as a function of spatial scale, water transparency and water depth. The carrying capacity of IJsselmeer for the production of prey fish was assessed, and a dynamic simulation model was constructed to predict consequences of fishery management measures on the fisheries and on the food availability for piscivorous birds.</p>
