В период 2009−2011 годов изучен планктон Усть-Куринского района Каспийского моря. Всего за времяисследований отмечено 48 видов планктонных инфузорий, 17 видов ветвистоусых, 3 вида коловраток и 2 вида веслоногих. Установлено, что на видовое разнообразие всех групп сильно влияет сток реки Кура, определяющий опресненность морской воды этого участка. Абсолютное большинство видов планктонного сообщества относится к пресноводным представителям или эврибионтным видам, способным существовать в широком диапазоне солености воды.

Abstract

Abstract. Plankton of Ust-Kura region of the Caspian Sea is studied in 2009–2011. Forty-eight species of planktonic ciliates, 17 species of Cladocera, 3 species of rotifers and 2 species of copepods are registered during the studies. Species diversity of all groups strongly influences the Kura River defining seawater desalination this site. The vast majority of species of plankton community refers to freshwater representatives or eurybiontic species able to exist in a wide range of salinity.

Methods

Methods.Collected samples for evaluation were examined diatomaceous plankton partially invivo, and then fixed with 4% formalin with addition of dye "Benqalrose". Further processing of the samples was carried out under laboratory conditions.

Results

Results. During the study 43 species of ciliates, 3 species of rotifers, 17 species of Cladocera and 2 species of copepods and their larval stages was noted (Table 1) . As seen from Table 1, the distribution of planktonic ciliates to collection points was fairly even and ranged from a minimum number of species reported by Article 1 (22 species) to a maximum at station 5 (31 species). It should also be noted that the vast majority mentioned in plankton ciliates are typical planktontam is distributed fairly evenly throughout the studied waters. Random plankton species, such as representatives of Condylostoma and Amphisiella were marked in shallow water stations 4 and 5. Apparently their presence in the samples is due to the temporary transfer of benthic plankton under the influence of the wave factor.
