Algica, an algae-based product created from nutrients exiting recirculating aquaculture systems, has the company poised to upscale production.
Shrimp hatcheries are highly dependent on continuous availability of clean water and proper treatment of effluents using sedimentation and biofiltration.
Pond water level management can reduce overflow volume and ground water use. Implementing BMPs reduces pollutant discharge.
In general, lower-intensity pond and cage farming tends to discharge higher overall pollution loads in farm effluents than closed aquaculture systems.
Research has shown that microbial mats are effective at removing nitrogen and phosphorus from aquaculture effluents.
Where aquaculture is key to food or employment, policies regarding effluent management should be flexible to address various species, systems and environments.
