How to control blue-green algae (filamentous/slime forming species) in low saline waters?
Water exchange is the most cost effective method. Incases where water exchange is not possible, aeration should be stopped during the strong sunlight period. This will allow the plankton to float on the surface where it will get pushed to the pond corner by the wind. The algae can be removed, or an algicide may be used in that corner of the pond to kill the algae. This is a low cost treatment method and safe for the shrimp since the chemical will be applied only to a small area. Repetition of this treatment may be necessary if the algae persists.
