No-maintenance filtration for hatcheries
A properly designed fluidized-bed filtration system increases hatchery output by providing a chemically stable, high-quality water supply.
Researchers are evaluating whether off-the-shelf flat-plate solar collectors can maintain stable recirculating aquaculture system temperatures.

Because of the high prices paid for live reef fish, overfishing of species such as groupers and Napoleon wrasse is a common problem throughout their range.
It would be difficult to find a pond aquaculture worker who has not measured Secchi disk visibility or at least seen someone measure it.
In pond culture, the application of formulated feed – some with very high protein content of 30-60 percent – constitutes the main nutrient input.
Phosphorus is one of the most scrutinized nutrients discharged by aquaculture systems, due to its potential eutrifying impact on receiving bodies of water.
Since 1985, white shrimp farming has developed significantly in northwestern Mexico along the coastal lagoons of the states of Nayarit, Sonora, and Sinaloa.
Zeolite is used in industry for water softening and as media for molecular sieves but has no real benefit for aquaculture in ammonia removal.
Cockles are a common, though not overly abundant, bivalve in British Columbia waters, where they are normally found in low intertidal and subtidal regions.
Bangladesh may be a small player in terms of global shrimp production, but producing and exporting shrimp provides an important source of foreign exchange.
Tilapia culture systems in Bangladesh play a “silent” role in meeting poor peoples’ needs and, increasingly, of a growing demand in formal markets.
Small autonomous vehicles provide an environmentally friendly approach to labor-intensive methods used to maintain production and water quality.
Total suspended solids concentration is time-consuming to measure, but turbidity has been used to estimate TSS concentrations in some types of effluents.
Since the application of mineral salts to correct ionic imbalances has improved survival and production, the practice is becoming increasingly common.
A technique to stimulate oyster growth in the form of an oyster reef breakwater is being developed at Louisiana State University in Baton Rouge.
Pure oxygen transfer columns and vacuum degassing columns can be used to drive dissolved nitrogen gas concentrations down to sub-saturation levels.
