Drum filters have been shown to be efficient in tests, although the effect of using different mesh sizes has not been clearly determined.
For oligotrophic (low nutrient levels) systems, where extremely high water quality must be attained, biofilters must be considered.
Because aquaculture is a water-intensive endeavor, conservationists have begun to inquire about the possibility of excessive water use in aquaculture.
Successful seaweed farms in the phycocolloid industry have been linked with the sustainable development of coastal communities.
In an integrated tilapia and duckweed recirculating system, the fish and the water of the ponds provide nutrients upon which the duckweed will thrive.
