The review concentrated on riverine migration defined in its broadest sense, and considered information from outside the UK where relevant. A critique of methods appropriate to the study of coarse fish migration was also carried out. Literature published up to April 1998 was covered, resulting in the examination of over 2000 articles of which nearly 450 are cited in this review. Additionally, information from continental Europe was obtained throughv isits to the Water Research Institute, Prague, Czech Republic, and the Laboratory of Fish Demography and Aquaculture, University of Liege, Belgium.
