| Abstract: | The succession of yield of fish species in European lakes undergoing cultural eutrophication is described. According to absence
or occurrence of yield increase two groups of fishes are distinguished. In few species a stepwise yield increase and intensified
yield fluctuations are observed. A decrease of the combinedCoregonus spp. is rarely found in deep lakes. In respect to adaptability to rapid eutrophication. three groups of fishes are distinguished:
preadapted fishes, obviously adapting ones, and not obviously adapting ones.
