Fish-friendly mowing
Cutting aquatic plants is necessary to ensure good water flow. For fish and other aquatic life, the arrival of the mower is quite disruptive. That is why we advise contractors and operators on how to mow in a fish-friendly manner and supervision the mowing activities.
Temporary oxygen deficiency
During maintenance work, the soil is sometimes disturbed and soil material begins to float. The water then turnsgrey color and a temporary oxygen deficiency occurs in the ditch. Fish are particularly affected by this. They come to the surface and gasp for oxygen. Unfortunately, this sometimes means that animals become temporarily paralyzed due to lack of oxygen or die if they are hit by the mowing bar. Unfortunately, it is not always possible to prevent the soil from being disturbed during mowing. We naturally try to prevent fish mortality.
Once the work is complete, the floating debris sinks back down and more oxygen becomes available for the fish. Many fish then recover and are able to swim away. Of course, it is unpleasant to see fish floating on the surface, but a healthy water system usually recovers quickly from mowing.
