What does "target organism" refer to in aquatic pest control?

The term "target organism" specifically refers to the pest species that are the focus of pest control efforts. In aquatic pest control, this means identifying and managing specific organisms that are causing harm to the ecosystem, such as invasive species or pests that threaten native plant life, fish populations, or water quality. By concentrating on the target organism, pest management strategies can be more effective and precise, minimizing impact on non-target species and the surrounding environment.

The other options do not accurately capture the concept of a target organism. For example, organisms benefiting from pest control may include native species that are helped by the reduction of invasive pests but are not themselves the target. Similarly, all aquatic plant species encompass a broader category that might include both beneficial and harmful plants, while microorganisms in the environment also do not directly relate to the specific focus of pest control efforts aimed at harmful species.
