Název v původním jazyce

Diversity and toxin content of cyanobacteria in fish ponds (South Moravia, Czech republic) related to fischery management intensity.

Popis výsledku v původním jazyce

During the vegetative period of the year 2005 (June-October) we carried out hydrobiological and hydrochemical monitoring of selected ponds inhered in Southern Moravia in relation to different fishery management intensities. Water temperature, dissolved oxygen content, pH, conductivity and water transparency were monitored directly at taking place, N-NH4+, N-NO2-, N-NO3-, P-PO43- content and chlorophyll-a concentration were measured in hydrochemical laboratory. At the same time, water samples for taxonomical analyses of phytoplankton and assessment of toxin content of cyanobacteria were taken. All ponds were characterized by low water transparency, high values of pH, N-NH4+, P-PO43- and high chlorophyll a concentration. We detected maximum concentrationof 18.7 ug.l-1 microcystins in ponds dominated by the species Microcystis aeruginosa. Total microcystin concentration in water of all ponds with dominance of pikoplanktonic cyanobacteria were below detection limit (LOD 0.125 ug.l-1). The
