The statement is true because when applying a fish toxicant in a partial treatment scenario, it is essential to start the application at the point farthest from shore. This practice minimizes the potential for the toxicant to drift toward the shoreline and adversely affect non-target aquatic life and habitats. By starting at the farthest point, the application can be conducted while keeping a greater distance from sensitive areas.

Additionally, sealing off the area to be treated with a curtain of fish toxicant is critical to prevent the toxicant from spreading to unintended areas. This containment helps ensure that the treatment is effective while protecting surrounding ecosystems. Overall, this approach reflects best management practices in aquatic toxicant application, prioritizing both effectiveness and environmental safety.
