Commercialization of modified fish and shellfish poses issues
Although controversial, the potential benefits of genetically modified fish and shellfish can yet be realized, while minimizing risks to human health and the environment.
Water quality standards: pH
The pH of shrimp pond water is influenced by source water, pH and acidity of bottom soil, shrimp culture inputs and biological activity.
Sea and brackish water recirculation systems for round and flat fish production, part 2
Recirculation systems not only limit environmental impact but can produce several species at once with minimal space requirements.
Family shrimp farm in Australia
Family shrimp farms are common in Southeast Asia, where costs of living are low and revenue from one or two small ponds can support a family.
EPA rule-making for aquaculture effluents in the United States
The history of how aquaculture's connection to the National Pollution Discharge Elimination System of the Clean Water Act is an interesting topic.
Culture of conch for stock enhancement and grow-out markets
The queen conch (Strombus gigas) is a large marine gastropod that has supported subsistence and commercial fisheries in these areas for centuries.
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.
Effluent composition and water quality standards
GAA's Responsible Aquaculture Program requires shrimp farmers to install certain practices, keep records on activities and satisfy effluent water quality standards.
Water composition and shrimp pond management
Natural waters have a very complex chemical composition and may contain almost any substance found in the atmosphere, in the Earth’s crust, or in living organisms.
Hydroponics and aquaculture: New systems for efficient food production
Archer Daniels Midland's hydroponics and aquaculture project utilizes waste heat and carbon dioxide to produce high-quality vegetables and tilapia on a year-round basis.
