What method is sometimes used in lakes to control AIS?

The use of biocontrol agents such as herbivorous fish is a recognized method for managing aquatic invasive species (AIS) in lakes. These fish can control the growth of invasive plant species by consuming them, thereby reducing their population and mitigating their impact on native ecosystems. This biological approach is beneficial because it typically has fewer environmental side effects compared to chemical treatments, and it can be a sustainable option if the introduced species are carefully chosen and monitored.

For instance, the introduction of specific herbivorous fish, like certain types of carp or tilapia, can help manage overgrown aquatic plants that disrupt local habitats. This method leverages natural processes, promoting a healthier balance in the aquatic ecosystem by allowing native flora and fauna to thrive, while simultaneously addressing the issues posed by invasive species.
