Hundreds of fish were found dead in Paraná, in the area that goes from the Chaco to the north of Santa Fe. The Ministry of the Environment assures that the phenomenon is due to the lack of oxygen and the flooding of the rivers, but the Locals suspect that the water is contaminated by the large amount of pesticides that come from the fumigation of the fields and specialists confirm this.

Thousands and thousands of Moray eels, Rays, Patíes, Surubíes, Manduvíes, Mojarras, Pacúes and Sábalos, have been dead from poisoning for days:

The government of Santa Fe prepared a report on the death of fish in rivers in the province. He points out that high temperatures, accompanied by a sudden rise in water flow, are causing a decrease in oxygen levels. The document warns that the recent flood dragged the organic matter from the lagoons, which added to the high temperatures and when it entered into decomposition, oxygen levels decreased even more.

The director of the Santafesina Food Safety Agency (Assal), Eduardo Elizalde, reported that the consumption of specimens, dead or dying in these circumstances, is strongly discouraged, since the fish decompose quickly and could represent a serious health risk.

What the locals and specialists say

“The contamination comes from above, we are seeing if it is from Asunción, although there is a good chance that it is from the Emilia ranch, which some Brazilians bought and made 9 thousand hectares of rice, they fumigated with phosphorous poison and that water all went into the river. That seems to me to be what is killing the most. The river water is possibly contaminated with poison, not the fish "

“Nobody buy fish. It is poisoned, it is contaminated and people can die- It rained a lot in the northern part and in the farms it was all watered with poison and as it rained a lot, the farm was filled with water and that water went to the river and is killing all the fish. Maximum alert in the part of Chaco, Santa Fe, Corrientes to the South "

"Something must be pulling our river, an impotence and anger feel those of us who know about fishing, when we go to look for what nature gives us for family consumption",to later tell his own experience,“Last year we went fishing with a group of friends and we saw with our own eyes how a liquid with a strong unbearable smell was discharged into the river from a channel that leads to Estancia la Hemilia, in those places even the trees dried up and it doesn't seem strange to me that something similar is happening ”,the fisherman speculated.

For his part, already in June 2017, the writer Patricio Eleisegui confirmed through the second installment of a study published by the magazine Environmental Monitoring and Assessment, that the waters and the riverbed of Paraguay and Paraná present high concentrations of glyphosate and insecticides such as endosulfan -which has been prohibited in the country since 2013-, cypermethrin and chlorpyrifos ”.

As in the first installment of the study published in July 2016, the monitoring bears the signature of, among others, Alicia Ronco - who died in November of last year - and Damián Marino, both specialists from Conicet and affirms that the degree of contamination detected exceeds the limits established for the protection of all aquatic life.

As Marino explained, the results come from samples taken in 2010 and 2012 in 22 different points of the mentioned basins. The work counted with the collaboration of the National Prefecture, which provided its logistics and the ship Luis Leloir for the transfer and performance of the scientists.

In its conclusions, the monitoring indicates that the high levels of pesticides found in water and sediments are caused by the use of these products for agricultural practice in all the territories that mainly crosses the Paraná.

“Intensive agriculture adds significant loads to tributaries in the middle and lower reaches and these then reach the main watercourse. Despite dilutions and discharges, the level of concentration is such that the products can be detected in the water stream. These findings expose the urgent need to regulate the application of pesticides in the basin ”, the work states.
