For example in vendace females occurring in brackish waters of the Gulf of Bothnia it fits 10-12%, whereas in neighbouring lakes Keitele and Pyhajarvi it is 23.9% and 19.3%, respectively. In Polish bodies of water the values of GSI are also very variable. In Lakes of West Pomerania (Bucerz, Krzemien, and Kalensko) te size of gonds constitued between 14.63 and 23.16% of the body weight of vendace. Even wider range was determined for Masurian Lakes Dargin, Dobskie, and Kisajno. The mean values of the gonadosomatic index of vendace from lakes of West Pomerania fitted into the above range, however, few specimens from lakes Pile and Pelcz showed low values of gonadosomatic index (GSI < 10%), whereas in a single vendace female from Morynskie Lake the value of the above parameter amounted to more than 30% of the fish body weight |
