Gonadosomatic index (GSI) of female whitefish (Coregonus lavaretus) in Lake Constance
AbstractFrom 1991 to 1997 the gonadosomatic index (GSI) of pelagic spawning female whitefish (Coregonus lavaretus, local name “Blaufelchen”) in Lake Constance-Obersee was determined. Average GSI increased from low values in summer to a maximum of about 24% immediately before spawning (end of November/beginning of December). The coefficient of variation
