South Moravia – A layer of pond with a layer of dead fish. Nightmares of all breeders can be one past. Researchers at Mendel University have begun investigating how massive death predicts.
The danger mainly occurs in hot summer days. In hot water, oxygen decreases. Especially from the weather, but also on the basis of other data such as the occurrence of cyanobacteria, scientists will compile what is called the predictive map of the possibility of death. "Our task is to monitor as many parameters as possible, placing them in relation to death," said Radovan Kopp of the Institute of Zoology, Fisheries, Hydrobiology and Animal Husbandry at the University.
With estimates, pool managers can take steps to keep the fish dead as little as possible.
The situation in the pool is also monitored by the farmers themselves, as announced by Fishmongers Pohorelice director Roman Osička. "We have to respond to climate change and not wait for the results of some scientific research. In the long run, we monitor the pond itself. But we and welcome to the project partners," he said.
This year, the biggest deaths were recorded by administrators in the Nesyt pond, Vlkavský or Kurdějovský pond. According to Koppa, several problems were repeated. This can be attributed to pollution, because only water from the wastewater treatment plant flows into the pond due to river dryness.
