Which is NOT one of the three major objectives of preventative aquatic weed control?

The primary objectives of preventative aquatic weed control focus on maintaining the ecological balance and preventing the proliferation of invasive species. One of the key goals is to deepen shallow waters, which can help reduce the growth of some aquatic weeds by limiting available sunlight and thus their ability to photosynthesize effectively.

Another major objective involves the elimination of contaminant sources, as pollutants can create favorable conditions for aquatic weed growth. Reducing nutrient runoff or other harmful substances is a vital part of preventing weed issues.

Prevention of weed spread is crucial in this context, as many invasive species can quickly dominate aquatic ecosystems, leading to negative environmental impacts. By implementing control measures that prevent the spread of these weeds, one can avoid larger problems in the future.

Enhancing fish populations, while beneficial for ecosystem health, is not one of the main objectives of preventative aquatic weed control. The focus is more on mitigating the conditions that allow weeds to thrive rather than directly improving fish populations.
