The Mediterranean copepod Calanipeda aquaedulcis Kritschagin, 1873 was first recorded in the Kuibyshev Reservoir in August 2015. It has been detected at all surveyed stations from the Volga-Kama reach to the dam of the Zhiguli hydroelectric power plant; the most northern finding of the copepod has been recorded in the mouth of the Kama River (55°24' N). C. aquaedulcis (0.3–7.3 thous. ind./m3 ) is in the group of dominant species and forms, on average, 13% of the total abundance and biomass of zooplankton. Comparatively large (1.0–1.4 mm) copepods reproduce intensively; females carry up to 18 eggs (on average 10 ± 0.6). The main part of the population (>90%) are represented by nauplii. The species has been found in smaller quantities (0.04–1.1 thous. ind./m3 ) throughout the Saratov Reservoir, which is located downstream the cascade. The ecology of the species and its potential importance in the zooplankton of the Volga reservoirs is discussed.
