Nitrogen control and protein recycling: Activated suspension ponds
Activated suspension ponds are effective at nitrogen control and protein recycling, functioning as a biofilter and as a microbial recycling system.
Microorganisms and feed management in aquaculture
Shrimp are the most commercially important aquaculture animals that utilize a significant amount of microorganisms in their diet.
Case studies of world shrimp farming
There have been few efforts to objectively assess the environmental and socioeconomic status of shrimp farming until recently.
Fences in the ocean
Erecting permanent structures in open coastal waters, like fish farms, requires planning, direction and, most likely, the grant of private property rights.
Aquaculture and the microbial world
Microorganisms reside in the sediment and other substrates, and in the water of aquaculture facilities, as well as in and on the cultured animals.
Formulating standards for effluent management
A major environmental consideration in shrimp farming is the negative impacts of pond effluents on coastal water quality.
Management of shrimp ponds to reduce the eutrophication potential of effluents
Nitrogen and phosphorus are contained in aquaculture pond effluents, and these two nutrients can cause eutrophication of natural waters.
Environmental codes of practice in aquaculture
In Prof. Boyd's first-ever article for the Advocate, he discusses how important environmental codes of practice are to aquaculture.
Mechanical pond water circulation: A new approach to shrimp farming
Circulation makes use of the very large amount of dissolved oxygen present on the pond's surface and distributes it down to the bottom.
