dc.description.abstractThis thesis deals with anthropogenic effects on the whitefish stock of Lake Constance in the time period 1950-2000. Eutrophication, size selective-fishery as well as stocking affects different whitefish traits such as somatic growth, reproductive investment as well as vertical distribution. Most of the analysis are based on fisheries data documented during the last 50 years.
This thesis shows that beside lake trophy, the practice of fishery itself could be a factor for ongoing growth depletion. Strong fluctuations in fish biomass acts strongly on growth rate as well.		eng

kops.description.abstractDiese Arbeit befasst sich mit anthropogenen Langzeiteffekten auf die Felchenpopulation des Bodensees im Zeitraum zwischen 1950-2000. Dabei konnte gezeigt werden, dass Eutrophierung, Besatz und die größenselektive Fischerei auf verschiedene Weise auf die Felchen wirken. Es konnten Zusammenhänge dieser Umweltfaktoren mit dem Wachstum, dem Reproduktionsinvestment, sowie der vertikalen Verteilung gezeigt werden. Der Großteil der Auswertung beruht auf der Datenanalyse von Fischereiaufzeichnungen der letzten Dekaden.deu
