Phytoplancton of the Kuibyshev reservior in August 2009

In August, 2009 researches of phytoplankton of the Kuibyshev reservoir are conducted. As a result, it is revealed that the Kamskiy reach is characterised by the greatest number of algae taxa with a rank below genus and the Priplotinnyy site - by the least one. The biggest number of species, versions and forms is registered by us in green seaweed department, but diatom seaweeds are most various in a separate test. In direction to the dam of Zhigulyevsk hydroelectric station the phytoplankton number and biomass increase. In Priplotinnyy site (especially its shallow parts) species of genera Oscillatoria and Lyngbia make considerable contribution to phytoplankton development. For the first time halophylic species of diatom seaweed Amphora coffeaeformis and Chaetoceros muelleri have been noted for the reservoir. Though caspian invasion species Actinocyclus normanii and Skeletonema subsalsum were present in the reservoir phytoplankton, but they did not reach considerable development during the investigated period.
