Hundreds, even thousands of dead fish floating in the river Dender in Ath, height lock Bilhée. Involved, the heat of recent weeks. The oxygen in the water becomes increasingly scarce. Fish do have enough to survive.
When you come up to the lock Bilhée is first smell that takes nose reeks of not fresh fish. Then hundreds of white spots floating on the water surface can be seen.
Jean, a septuagenarian Lessines, just go back to bike along the Dender. He saw a lot of dead fish. He is not happy. “It should not happen. Fishermen pay for their fish. Yonder, further downstream, there are much more, ten times more.”
For a few days the fish are dead, but they only begin to rise to the surface. This carnage is due to the scorching weather. “Oxygen is already dissolved in water more difficult because of the heat,” said Baudouin Vervaeke, the fire chief of Ath. “And green microalgae are formed on the surface of the river. To grow, they consume oxygen at the expense of fish. ”
The only way to limit the damage is to bring more oxygen through a machine. “Waterways have placed a machine in the river, an aerator, which will circulate the water in a violent manner. The air is incorporated into the water, and also oxygen. ”
