What is the purpose of using benthic barriers in aquatic pest management?

The purpose of using benthic barriers in aquatic pest management is to cover bottom sediments with material. This method is effective in managing unwanted aquatic plants and pests by physically blocking sunlight and inhibiting their growth. Benthic barriers are typically made of materials such as geotextile fabric, and by depriving the targeted organisms of light, the barriers help reduce their proliferation in the waterbody.

Using benthic barriers can limit the spread of invasive species or unwanted vegetation without the use of chemicals, making it an environmentally friendly option. While other methods in aquatic pest management may address issues like water aeration, invasive species removal, or water quality enhancement, the specific function of benthic barriers is centered around the physical coverage of the substrate to mitigate undesirable biological growth.
