Responsibility
Mechanical water circulation aids pond water quality
Mechanical water circulation can prevent stratification and provide more dissolved oxygen near pond bottoms. Strong water mixing can also control algae growth.
Responsibility
Assessing, reducing pond seepage
Ponds constructed on sandy or permeable soils are most likely to have high seepage rates. Ponds built in any soil can seep if improperlty constructed.
Responsibility
Tractor-powered paddlewheels provide emergency pond aeration
Even with dedicated aerators, aquaculture farms can experience stress and mortality in culture animals due to low dissolved oxygen concentrations in pond water. Simple tractor-powered aerators offer a quick and portable solution to low dissolved oxygen levels that provides strong emergency aeration and water movement.
Responsibility
Improved aeration, D.O. management advance catfish production
Emergency aeration with tractor-powered paddlewheels allowed U.S. catfish farmers to increase feeding and stocking rates, and double production.
Responsibility
PDP (pressure differential piping) aeration
For shrimp growers committed to using mechanical aeration and intensive culture densities, electrical power consumption is a major cost.
Responsibility
Aeration, mixing and sludge control in shrimp ponds
A benefit of aeration is the mixing of pond water. Similar to biotechnological reactors, microbial processes are more effective in mixed pond water.
Responsibility
Round peg in a square hole: Aeration in a square shrimp pond
Appropriate site selection, design and management are fundamental factors that contribute to the success or failure of a shrimp farm.
