| Abstract: | In recent years yields of the Alpine char fishery of Lake Zug have only been about 5% of traditional yields at the turn of the century. Major results of a biological investigation of the species are presented. Management implications based on the biological study, that should reverse the trend of diminishing yields, are made. |
