What term describes the alteration of the food web to improve water clarity?

The term that describes the alteration of the food web to improve water clarity is biomanipulation. This approach often involves modifying the populations of certain fish or invertebrate species to enhance the ecological balance within a water body. For instance, biomanipulation can include decreasing the number of herbivorous fish that may prevent the growth of algae and allow for clearer water. By promoting the growth of phytoplankton or zooplankton, it is possible to improve water clarity and ultimately enhance the overall health of the aquatic ecosystem.

Other terms, while related to ecological processes, do not specifically refer to this particular method. Ecosystem engineering refers to species that create, modify, maintain, or destroy habitats, impacting the structure of ecosystems but not directly targeting water clarity through food web manipulation. Catalytic adjustment is not a widely recognized term in this context, and ecological restoration involves restoring an ecosystem to its original state rather than managing the food web for clarity improvements.
