Treatment of shrimp hatchery effluents
Shrimp hatcheries are highly dependent on continuous availability of clean water and proper treatment of effluents using sedimentation and biofiltration.

Swedish innovators create multiple revenue streams from effluent
Algica, an algae-based product created from nutrients exiting recirculating aquaculture systems, has the company poised to upscale production.
Responsibility
Water level management, BMPs cut water use, pond effluents
Pond water level management can reduce overflow volume and ground water use. Implementing BMPs reduces pollutant discharge.
Responsibility
Effluent effects from aquaculture ponds
In general, lower-intensity pond and cage farming tends to discharge higher overall pollution loads in farm effluents than closed aquaculture systems.
Responsibility
Microbial mats remove nitrogen, phosphorus from aquaculture effluents
Research has shown that microbial mats are effective at removing nitrogen and phosphorus from aquaculture effluents.
Responsibility
No single solution for effluent management
Where aquaculture is key to food or employment, policies regarding effluent management should be flexible to address various species, systems and environments.
Responsibility
Effluent permits commonly required by governments
A major environmental concern related to shrimp aquaculture is the potential water pollution from the release of effluent into water bodies.
Responsibility
EPA rule-making for aquaculture effluents in the United States
The history of how aquaculture's connection to the National Pollution Discharge Elimination System of the Clean Water Act is an interesting topic.
Responsibility
Effluent composition and water quality standards
GAA's Responsible Aquaculture Program requires shrimp farmers to install certain practices, keep records on activities and satisfy effluent water quality standards.
Responsibility
Farm effluent during draining for harvest
Settling basins seem to be the only practical means of treating effluents released during harvest at small or large shrimp farms.
Responsibility
Treatment of shrimp pond effluent using constructed wetlands
This paper reports on the use of a constructed saltwater wetland system to treat effluent from a pilot facility consisting of four 2-ha ponds.
Responsibility
Formulating standards for effluent management
A major environmental consideration in shrimp farming is the negative impacts of pond effluents on coastal water quality.
