| Abstract: | The reactions of the bream,Abramis brama, to the ecological changes due to man-made eutrophication of Lake Constance were investigated.
It could be demonstrated that the bream adapted only to a negligible amount. Likely due to its largeness, structure of the
body and population composition the bream is more conservative than perch, roach and whitefish. The only reactions to the
changed environment are modificated vertical and horizontal distribution and partly plancton feeding in summer.
