Wild and hatchery-reared 8-12-month-old (5-8 cm) trout, Salmo truttu L., were stocked into tributaries of the River Gudeni. Movements were examined by means of electrofishing. Overall dispersal and upstream movement weregreater for wild trout than for domestic trout. Maximum distance of movement was 600 m upstream for both strains and 600 m downstream for wild trout, and 700 m for domestic trout. Upstream movement started within 2 months from stocking and continued for at least 4 months. Downstream movement during the first few days after stocking, was more pronounced for domestic trout than for wild trout.
