Hundreds of Lifeless Fish Appear in the Mouth of Nosara River

By Oliver Pérez

The increased appearance of dead fish in the last few days reached the boca (mouth) of Nosara River, where Olivier Von Der Weid’s camera captured hundreds of fish that turned up lifeless the morning of Sunday, April 8th at the edge of the river. 

According to biologist Elizabeth Fernandez, head of the municipal environmental office, told VON that the strongest hypothesis is that the creatures died because of what is called red tide, thus named because the sea takes on a reddish tint.  

According to the professional, it could have occurred at a moment when the tide was rising and contaminated this part of the river. 

“The Ministry of Environment ought to determine, by means of a Toxicology laboratory, to come to a conclusion as to the cause of the death of all of these fish,” indicated the biologist.

For his part, when this medium consulted Luis Dobles, executive president of Incopesca, said, “The behavior has been monitored permanently by the corresponding authorities and by the Commission on Red Tide and, to date, all of the laboratory tests performed have come back negative as far as if the phenomenon has become toxic for the fish and mollusks that are normally affected, much less for human beings.”

 


Red Tide consists of the concentration of marine microorganisms called dinoflagellates, which produce toxins that build up in the algae and later consume the mollusks. 

The mollusks function as filters of this toxin and store it in large quantities. 

Neighbors in the areas where the dead fish appeared opted to burn the bodies of the animals. 

This is due to the foul odor they let off and the lack of actions on the part of authorities. 
   
For now, the results must be awaited from the Ministry of Environment, Energy and Telecommunications (MINAET) to conclude the cause of the death of the fish.
