The heat may have caused the death of fish that were found in Rio Muriaé on Monday (20) in Muriaé Center in Zona da Mata. The resident Luiz Felipe Souza works close to where the fish were, in Prainha, where there is the meeting of the rivers Muriaé and Black, known as “Remanso”. He said he did not need the amount of animals that were lifeless. “There were many. And the water was very dark and shallow. It never happened, “he said. The municipal secretary of Environment, Juliana Guarino, believes that the excess heat from the low water level caused the carnage. The removal of dead fish was taken on the morning of Tuesday (21).

Also according to the resident, the water was smelly. “We have a hose that is used with water taken from the river. The hose could not be used yesterday (Monday, 21) because of it, “he complained. 

The removal of dead fish was carried out by the Municipal Environment, with support from Environment Environment Police, firefighters and Municipal Department of Urban Sanitation (Demsur). According to the municipal secretary of Environment, Juliana Guarino, water analyzes will be done to detect what may have occurred. She believes that the excess heat from the low water level caused the carnage. “The biggest suspicion is that really the lack of rain, with the low level of the river, has generated little oxygen on site. Fish seek this oxygenation, but are not managing, “he explained. It is expected that the test results be disclosed within five business days.

On the bad smell in the water, the secretariat explained that the problem is caused by the lack of a proper sewage treatment in the city. “When it lowers the volume of water, there is no movement, the sewer is stopped and gives the smell,” he said. Juliana Guarino also said that cleaning was done in the river on Tuesday morning and the staff made the move in the waters to try to reduce the problems.
