Popis: | The contranatant migration of juvenile cyprinids was studied in the Volga River delta in September–November 2016. A motivational component of rheoreaction (the ratio of rheoreaction types) of migrating and nonmigrating juveniles was evaluated in the course of experiments. It is shown that the motivational component of rheoreaction is a behavioral mechanism of contranatant migration. |
