Retrospective review of ichthyofauna of small rivers of Samara region

The article summarises the research information on the species composition of ichthyofauna of small rivers of Samara region. It is shown that active study was carried out in the second half of the last century. Small rivers are characterised by rapid changes in ecosystems, their ichthyofauna is most sensitive to the action of various anthropogenic and natural factors, which contributes to changes in the species composition of fish. At present, it is necessary to further study the hydrobiology of small rivers in the region and inventory the existing data.
