How do you get rid of Euglena from aquaculture pond?

To manage Euglena in an aquaculture pond, consider adjusting the water's nutrient levels by reducing excess nitrogen and phosphorus, as these can promote their growth. Implementing regular water changes and increasing aeration can help improve water quality. Adding beneficial microorganisms or competing algae can also help outcompete Euglena for resources. In severe cases, physical removal or the use of targeted algaecides may be necessary, but always ensure these methods are safe for the aquatic ecosystem.
