What are some alternatives to chemical pesticides in aquatic pest management?

Biological control is a widely recognized and effective alternative to chemical pesticides in managing aquatic pests. This approach utilizes natural predators, parasites, or pathogens to control pest populations. For instance, introducing specific fish species that feed on invasive aquatic weeds can help maintain their populations at manageable levels. By promoting the ecosystem's natural balance, biological control can reduce reliance on synthetic chemicals and minimize potential negative environmental impacts.

In contrast, while mechanical engineering can play a role in managing aquatic pests through methods like removal or barrier installation, it typically does not provide a sustainable long-term solution. Market regulation and soil amendment are not relevant alternatives within the context of directly managing aquatic pest populations. Understanding the role of biological control can empower pest managers to use integrated pest management strategies that prioritize ecological health and sustainability.
