Age and Growth of the European Bitterling Rhodeus amarus (Cyprinidae, Actinopterygii), in the Uday and Perevod Rivers (Dnipro basin, Ukraine)
Age and growth of the European bitterling were investigated in the Uday River and the Perevod River at the National Nature Park "Pyriatynsky" (Poltava region, Ukraine) in 2017–19. The studied population of the European bitterling was represented by five age groups (0+ to 4+). Age was deter...

The studied population of the European bitterling was represented by five age groups (0+ to 4+). Age was determined by counting annuli on scales.
