Fish-friendly mowing
Mowing aquatic plants is necessary for proper water flow. For fish and other aquatic life, it is quite invasive when the mower passes by. That's why we advise contractors and operators on how to mow in a fish-friendly way and supervise the mowing operations.
Temporary oxygen deficiency
During maintenance work, the soil is sometimes turned over and soil material begins to float. The water is then brown/gray in color and there is a temporary lack of oxygen in the ditch. Fish are particularly affected. They come to the surface and gasp for oxygen. Sometimes, unfortunately, this means that animals become temporarily paralyzed due to lack of oxygen or die when they are hit by the cutter bar. Unfortunately, stirring the bottom during mowing operations cannot always be prevented. Fish mortality, of course, is something we try to prevent.
When the work is finished, the suspended solids settle again and more oxygen becomes available to the fish. Many fish then recover and can swim away. Of course, it's an annoying sight, those floating fish, but a healthy water system usually recovers quickly from mowing.
