Floating skimmers improve water quality in tanks, ponds
In aquaculture, foam fractionation involves the use of a protein skimmer to remove dissolved organic compounds from aquaculture systems.
Responsibility
Probiotics’ enhancement of soil, water quality examined
Probiotics used as bottom soil and water quality enhancers are primarily cultures of living bacteria, enzyme preparations, or the two combined.
Responsibility
Organic matter in pond bottom sediment
Organic matter – including fertilizers, unconsumed feed and feces of culture animals – settles to pond bottoms, often with a negative impact on water quality.
Health & Welfare
Water quality concerns may move up food chain
Consumer interest in water quality may prompt industry to further limit chemical use and improve biosecurity programs as an alternative to antibiotics.

Determining ion concentrations for Litopenaeus vannamei culture in freshwater
Future increases in U.S. shrimp farming are likely to be inland, which entails the use of ground waters with an ion concentration vastly different from seawater.
Responsibility
Anion-cation balance in water
The ionic composition of inland well water can vary from suitable to toxic to cultured animals. Reliable data on concentrations of major cations (calcium, magnesium, potassium, and sodium) and major anions (bicarbonate, sulfate, and chloride) is therefore important in the management of waters for inland shrimp farming.
