Abstract
The spread of crustaceans of the order Cumacea in the Dnieper reservoirs is analyzed in the paper. It is thought that these crustaceans could get into the newly formed reservoirs along with the introduced Gammaridae, Mysidae, and Mollusca. In all reservoirs of the Dnieper cascade, except for the Kyiv Reservoir, where they have not been found till now, 4-5 species of Cumacea have been registered. Pterocuma pectinata (Sow.) dominates in terms of the quantitative indices of its development. During the period of investigations, the numbers and biomass of Cumacea accounted for respectively 25-131 specimens/m2 and 0.06-0.13 g/m2. The highest quantitative indices of Cumacea development were observed at the depths of 2-7 m on sands and silted sands.
期刊介绍：
This journal contains translations from the premier Russian and Eastern European periodicals in aquatic biology and aquatic ecosystems, supplemented by original articles from elsewhere. The journal publishes in the area of physiology, biochemistry, systematics, ecology and conservation of freshwater fish, invertebrates, vascular plants, zoo- and phytoplankton, as well as freshwater quality and toxicology. While most of the papers deal with inland waters, the journal also publishes articles reporting on expeditionary work, especially the Antarctic and tropical seas. Hydrobiological Journal is valuable to freshwater and marine biologists and chemists, limnologists, environmental scientists, oceanographers, and toxicologists.
