In spring 1984 sea trout larvae were released into the upper stretch of Osówka Stream. Smolts grown from this material were caught in three consecutive years after the fish release, using a fish trap placed in the middle course of the stream. The materials were used to determine fish sex and sex ratio, gonad condition and development, length and weight of males and females; and condition of sea trout smolts of known age.
