A mystery is currently baffling residents and officials in Paraguay.
Look! This fisherman is literally sailing on a river (Montelindo River) of dead fish.

What a shock! Look at the thousands of dead fish floating on the surface of Montelindo River, Paraguay, just eight kilometers away from the mouth of the Paraguay river.
The mysterious sight generated great concern among the residents of the area. Locals urged officials to investigate the fish mass die-off.
Meanwhile water samples are being analyzed. One of the hypothesis behind the death is organic matter from decomposing vegetation and dead animals. Another cause could be a lack of oxygen.
The area is surrounded by farms. Did pesticides get into the water? [Primera Edicion]
