Which of the following strategies helps manage aquatic invasive species effectively?

Implementing early detection programs is a highly effective strategy for managing aquatic invasive species. These programs focus on closely monitoring ecosystems to identify invasive species at their initial stages of introduction. The earlier an invasive species is detected, the more options there are for management and control, which can prevent them from establishing and spreading further.

Early detection allows for quick responses, such as targeted removal or control measures, and can help mitigate potential ecological, economic, and social impacts associated with invasive species. This proactive approach enhances the overall health of aquatic ecosystems by allowing for timely intervention before invasive species can outcompete native species or disrupt the habitat.

In contrast, overapplication of herbicides may lead to further ecological damage and resistance, ignoring early signs can result in unchecked spread of invasive species, and maximizing nutrient runoff typically increases the growth of unwanted aquatic plants and organisms, exacerbating the problem. Each of these strategies does not provide the proactive, preventive approach that early detection programs advocate, emphasizing the importance of early intervention in maintaining healthy aquatic environments.
