For the first time, a morphometric description of the rudd Scardinius erythrophthalmus (Linnaeus) in the backwater zone of the Shumarovka River influenced by the Rybinsk Reservoir and lakes Chistoye and Sankhar is presented. The rudd from the Shumarovka River belongs to the generation of the anomalously warm year 2010. According to a combination of analyzed features, the rudd from the Shumarovka River is similar to the fish of this species of Lake Chistoye, but differs from the rudd of the karst Lake Sankhar. The study suggests that scale initiation and formation in the lateral line and the number of pores of the seismosensory system in rudd depends on the rates of its development and growth at its early life stage.
