Sea trout larvae were released in spring 1984 into the upper sector of Osówka Stream. Smolts of these fish were caught in three consecutive years after larvae release, in a fish trap placed in the middle course of the stream. The materials collected were used to determine period and water temperature at which smolts migrated downstream, as well as smolt length, weight and age composition.
