Fish community structure in the Dnipro-Orilskiy Nature Reserve, Ukraine (1987–2015)

It includes occurrence records with spatial and temporal attributes, species identification, and counts of juvenile fish collected by standardized seining in various aquatic habitats (lakes, channels, river stretches). The data offer valuable insights into recruitment success, biodiversity dynamics, and the ecological response of freshwater fish communities to eutrophication and climatic variability.

This resource supports biodiversity monitoring, conservation planning, and ecological research in large floodplain river systems.
