Annotation	The effect of water temperature and flow on the migration of fish was observed in the River Elbe (Střekov fishpass, Czech Republic) in 2003 and 2004. The effect was examined separately for immature and adult fish and also the most abundant species (R. rutilus, A. alburnus, Squalius cephalus, G. gobio). The highest levels of fish occurrence in the fishpass were observed during the spring spawning migrations of adults as well as during the late summer and fall migrations of adult and immature fish. While the total number of both fish age categories was significantly related to the interaction of water temperature and flow, however, responses of individual species and age categories differed from each other. Immature fish and small- and middle-sized species required lower values of water flow than adult fish or large species. The exception was G. gobio, which required higher values of flow for its migration, a feature that could be related to its bottom dwelling nature or rheophily.
