In the daytime, about 99.9% of the juvenile fish community from the plant-rich Zlutice Reservoir was found in the nearshore belt of submerged aquatic vegetation reaching an average abundance of similar to 7982 inds. 1000 m(-3). In contrast, in the pelagic habitat, few fish were found at day. In the plant-poor Rimov Reservoir, 98.9% of juveniles occupied the pelagic habitat during daytime and reached an average abundance of similar to 333 inds. 1000 m(-3). Vertical distribution of fish in the pelagic habitat in both water bodies was affected by steep thermal and oxygen stratification and no individuals occurred below 6 m depth. At night, 88.8% of the juvenile fish community from the plant-rich Zlutice Reservoir was in the pelagic habitat with an average abundance of similar to 1423 inds. 1000 m(-3). Their diel horizontal shifts were much more pronounced compared to the community from the Rimov Reservoir that reached an average nighttime pelagic abundance of similar to 523 inds. 1000 m(-3). Only 1.1% of the juvenile fish community in the Rimov Reservoir was found in the littoral during the daytime and 0.7% at night reaching an average daytime abundance of similar to 1688 inds. 1000 m(-3) and average nighttime time abundance of similar to 1664 inds. 1000 m(-3). This study indicates that if a well-developed littoral zone with abundant aquatic vegetation is present, early juvenile fish will perform diel horizontal movement in temperate stratified reservoirs.
