Reproduction, growth, and migration of fishes in a regulated lowland tributary: potential recruitmens, reduced hydrological connectivity to the floodplains and a lack of spawning and nursery areas for many fish species. In such regulated rivers, tributaries may be particularly important for recruitment of fish populations in the main channel. This paper describes the reproduction, growth and migra
