Dynamic of the Phytoplankton Community in Eutrophic Fishponds

Popis výsledku v původním jazyce

Research was conducted in three fishponds, located in the area of the municipalities Šumice and Pohořelice in South Moravian region, in period from April to September 2015. Samples for phytoplankton analyses were collected twice a month, using plankton net and sampling bottles. At same time, by using portable field devices and Secchi disk, water temperature, dissolved oxygen, pH, conductivity and transparency were measured. A total of 153 taxa of the phytoplankton (27 taxa of cyanobacteria and 126 of algae) were documented in the studied ponds. The most abundant phytoplankton was in Šumický horní pond, in which big fluctuation in abundance was recorded over the study period. Cyanobacteria, over the entire year, were the most dominant group in this pond. Main representatives were from genera Microcystis. In Šumický dolní pond the most numerous were the green algae, with the genera Desmodesmus, Pediastrum, Scenedesmus and Crucigenia tetrapedia, which was the most abundant species in July and August. In Pohořelický pond, after a short period at the beginning of the season when low diversity and number of phytoplankton was documented, a dominance of green algae occurred, subsequently followed by the dominance of trichal cyanobacteria Planktothrix agardhii, Cuspidothrix issatschenkoi and Aphanizomenon flos-aqua. In all three ponds algae and cyanobacteria which correlated with the eutrophic and hypertrophic water systems were registered.
