Phytoplankton dynamic of small fishponds during the application of bacterial product

Original language description

Qualitative and quantitative analyses of phytoplankton community were carried out in fishponds Bohuslavice 1, Bohuslavice 2 and Bohuslavice 3 situated in the District Prostějov, during the period from April to August 2017. In Bohuslavice 2 and 3 bacterial product PTP PLUS was applied in several repetitions in April and May with the aim of decomposing the organic sediments at the bottom and improving the oxygen regime. At the same time, selected hydrochemical parameters were measured. The highest values of oxygen saturation were documented at the beginning of the season, after which they continuously decreased. Taxa from eight divisions were recorded in the phytoplankton community. In terms of diversity, Chlorophyta was the most diverse group, followed by Bacillariophyta and Euglenophyta in each of the studied fishponds. The highest abundance in Bohuslavice 1 and 2 was recorded in the beginning of the research period, and this was the only time when cyanobacteria were present in higher numbers. In Bohuslavice 2 the highest value of abundance was in July, with Tetrastrum triangulare as the most dominant species (48.87% of total amount of cells); and this was the highest abundance registered in all three ponds during the entire research period. The most dominant group during greater part of the season was Chlorophyta with common representatives from genera Monoraphidium, Desmodesmus, Planktosphaeria, Tetrastrum. Very numerous members of phytoplankton community were also genera Trachelomonas, from the group Euglenophyta and colonial Fragilaria from Bacillariophyta. The oxygen content, diversity and abundance of phytoplankton were probably influenced by the cover of free floating plants Lemna minor and Spirodela polyrhiza, which were present in different scales in all three ponds.
