Mechanical pond aerators increase the rate at which oxygen from air enters water by providing a greater surface area to facilitate diffusion.
Integrated cage-cum-pond systems are high-value species are stocked in cages suspended in ponds with filter-feeding species stocked in open water.
Feeding allows much greater production of fish and shrimp, but nutrients in feed are not converted completely to fish or shrimp flesh.
For shrimp growers committed to using mechanical aeration and intensive culture densities, electrical power consumption is a major cost.
The authors integrated a vegetated filter strip into a commercial catfish pond to capture effluent as part of best management practices.
Probiotics used as bottom soil and water quality enhancers are primarily cultures of living bacteria, enzyme preparations, or the two combined.
Authors are developing a freshwater hatchery effluent bioremediation system that uses seaweed polyculture to decrease discharge levels and reduce remediation costs.
In aquaculture, foam fractionation involves the use of a protein skimmer to remove dissolved organic compounds from aquaculture systems.
Researchers are evaluating whether off-the-shelf flat-plate solar collectors can maintain stable recirculating aquaculture system temperatures.
