The influence of coagulant PAX-18 on Planktothrix agardhii bloom in a shallow eutrophic fish pond

Original language description

For the first time in the Czech Republic, the PAX-18 coagulant has been used to restore a eutrophic fishpond. The polyaluminium hydrochloride coagulant was applied repeatedly to a shallow eutrophic fishpond in spring 2005. Two cylindrical plastic enclosures were used to isolate parts of the pond as untreated controls. Selected environmental variables were measured in situ. Water samples were analyzed regularly for nutrients, chlorophyll a concentration and phytoplankton abundance and structure with special focus on Planktothrix agardhii. The PAX-18 treatment led to a marked increase in the N/P ratio and changes in the structure and abundance of phytoplankton in the fishpond and P. agardhii blooms were eliminated in the fishpond. By contrast, P. agardhii dominated the phytoplankton in the control enclosures, as it had in the fishpond in 2004, prior to the PAX?18 treatment.

Vliv koagulátu PAX-18 na vodní květ Planktothrix agardhii v mělkém eutrofním rybníku

Czech description

Poprvé byl použit koagulát PAX-18 na revitalizaci rybníka. Výsledkem zákroku byla redukce vodního květu Planktothrix oproti kontrole i oproti předchozí sezóně. Výsledky jsou dokumentovány nejen na chemických parametrech, ale hlavně na dynamice a struktuře planktonu.
