The impact of fishery on the state of populations of the European whitefish Coregonus lavaretus in Lake Imandra
Abstract -The impact of fishery on the state of populations of the European whitefish Coregonus lavaretus in Lake Imandra, the largest water body of the Kola Peninsula, is considered. The retrospective analysis of catches in the period of 1930 to 1998 indicated that the consequences of an uncontroll...
