THE GROWTH OF GRAYLING (THYMALLUS THYMALLUS L.) IN THE KUPA RIVER
The growth of grayling (Thymallus thymallus L.) was analyzed on specimen of 98 fish, caught whit sport-fishing equipment in upper part of the Kupa river, northwest Croatia. The research was conducted in 2002 fishing season, monthly from May to November. The total length of caught grayling ranged fro...
