| Abstract: | The fishery of twoCoregonus sp. of the Lake of Neuchâtel (Switzerland) were studied with statistics held since 1917. The younger age structure observed in 1978–80 due to eutrophication which enabled a faster growing of the fishes permits to explain the decrease in fish numbers as well as in weight of the catches. |
