South Moravian – Lagoon layer with a layer of dead fish. The nightmare of all creators can be a past. Researchers at Mendel University have begun to investigate how massive deaths predict.
The danger is mostly on hot summer days. In hot water, oxygen is reduced. Especially from the climate, but also based on other data, such as the occurrence of cyanobacteria, the scientist will compile the so-called predictive map of possible death. "Our task is to monitor as many parameters as possible by putting them in contact with mortality," said Radovan Kopp of the University's Institute of Zoology, Fisheries, Hydrobiology and Beekeeping.
With predictions, pond managers can take steps to keep dead fish as little as possible.
The situation in the lagoons is also monitored by the breeders themselves, as announced by the director of the Fishery Pohorelice Roman Osička. "We have to respond to climate change and not wait for the results of some scientific research. In the long term, we are monitoring the lakes themselves, but we are welcome to project partners," he said.
This year, the highest mortality was recorded by managers in the Nesyt, Vlkavský or Kurdějovský lagoons. According to Koppa, some problems recur. This may be related to pollution, because only the water from sewage treatment plants flows into the ponds due to the river drought.
