Inland shrimp farming and the environment
Inland shrimp farming has been a common practice in some areas of Thailand for nearly a decade and interest in this activity is spreading.
Biochemical oxygen demand is an index of the oxygen demand in wastewater, an important water quality variable used in effluent management.

For seawater or brackish water aquaculture management, the salicylate method is best for total ammonia nitrogen analysis.
A major environmental concern related to shrimp aquaculture is the potential water pollution from the release of effluent into water bodies.
Two nutrient elements, nitrogen and phosphorus, are responsible for eutrophication in most instances. Phosphorus is usually the key factor.
We sampled pond bottom sediments from 45 commercial channel catfish ponds that were in production for 14 days to 21 years.
Some producers take advantage of shrimp's ability to tolerate a broad range of salinity variations by rearing in low-salinity waters.
A benefit of aeration is the mixing of pond water. Similar to biotechnological reactors, microbial processes are more effective in mixed pond water.
Tilapia-shrimp polyculture may provide an opportunity to re-establish a profitable and more sustainable aquaculture system at these dormant facilities.
In shrimp farming it is critical to ensure that residual nitrogen waste is minimized or eliminated prior to discharge into receiving waters.
Solids in water are either in true solution or suspended. Suspended solids remain in suspension because they are so small and light.
The pH of shrimp pond water is influenced by source water, pH and acidity of bottom soil, shrimp culture inputs and biological activity.
Although controversial, the potential benefits of genetically modified fish and shellfish can yet be realized, while minimizing risks to human health and the environment.
Recirculation systems not only limit environmental impact but can produce several species at once with minimal space requirements.
Family shrimp farms are common in Southeast Asia, where costs of living are low and revenue from one or two small ponds can support a family.
The history of how aquaculture's connection to the National Pollution Discharge Elimination System of the Clean Water Act is an interesting topic.
