Characteristics of species diversity of phytoplankton in fish-breeding ponds
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 103, Issue
Abstract
Phytoplankton is part of plankton, which is represented by plant organisms, adapted to ‘soar’ in the water mass. It is the basis of the biodiversity of aquatic ecosystems because it can produce autochthonous organic matter and saturate the aqueous layer with dissolved oxygen. Phytoplankton is characterized by high species and taxonomic diversity, an indicator of their trophy and indicator of saprophy. In the spring, summer and autumn periods. we studied the taxonomic composition, phytoplankton biomass and number, the information diversity (Shannon index), the index of saprophy in the fish-breeding ponds of the Bila Tserkva experimental hydrobiological station of the Institute of Hydrobiology of the NAS of Ukraine (BEНS IНB of the NAS of Ukraine, Bila Tserkva), Nyvka research farm of the Institute of Fisheries of the NAAS of Ukraine (Nyvka research farm, IF of the NAAS of Ukraine, Kyiv), Scientific-Production Fishery Laboratory of the Department of Aquaculture of the National University of Life and Environmental Sciences of Ukraine (Nemishaive town, SPFL of the NUBiP of Ukraine). In different periods, the following divisions represented phytoplankton of ponds on farms: Cyanophyta, Dinophyta, Cryptophyta, Euglenophyta, Chlorophyta, Chrysophyta, Bacillariophyta, Xanthophyta. The leading place in the number of species during a significant part of the growing season belonged to green algae, whose intensity depended on water temperature; blue-green, diatom algae and euglen ones were less important; golden, dinophytic, cryptophytic and yellow-green algae played a minor role.
