On the basis of spatio-temporal analyses of recaptured tagged common carp, the local movements (migrations), growth and length-weight parameters were monitored in the Novomlýnská reservoir. Generally, 28 % of fish migrated upstream within the distance of 28.9 km, 19 % of tagged recaptured fish migrated in downstream direction up to a distance of 30.5 km and 53 % of the studied fishs were stationary in the Novomlýnská reservoir. The highest migration activity was ascertained during the 1st and 2nd year after stocking. The recapture rate of the overall 10.000 stocked fish, was only 1 %. Already 12 months after stocking, the mean total length (TL) of recaptured fish reached 465 mm, weight (w) 2200 g and Fulton´s condition factor (FWCF) 2.45.
