In spring 1987 the fry of sea trout was introduced into the upstream of Osówka. Smolts grown from this material were caught during three successive years after the fish release, with the aid of fish trap situated in the middle course of the stream. Sex, condition and coefficient of gonads development, as well as length, weight and condition factor of smolts of the known age were determined.
