Measuring impacts of marine aquaculture partnerships
A survey of aquaculture partnership participants helped understand problems and perceptions associated with the expansion of U.S. marine aquaculture.
Drying, liming, other treatments disinfect pond bottoms
The traditional way of destroying organisms in pond bottoms is thorough dry-out for a week or longer. Fish toxicants and liming can kill unwanted parasites.
Non-native fish species present farming opportunities, challenges in Bangladesh
Fish supply is a food security priority in Bangladesh. There is potential for the culture of non-native fish species to meet its growing population's needs.
Economics of farm certification: Balance benefits, costs
While there are environmental, social and economic benefits from aquaculture facility certification, farms bear most of the costs, at least initially: procedures, equipment and services to achieve compliance. There are risks that new procedures could affect productivity and raise production costs.
Texas research advances water treatment methods for intensive biofloc raceways
Shrimp production studies using biofloc technology at the AgriLife Research Mariculture Lab in Texas evaluated different approaches to maintain water quality.
Feed trays or broadcasting?
At higher stocking densities, the application of all feed via feed trays often results in feed being dropped outside and/or underneath the trays.
Prevent, but verify
Each farm unit should have a written program that defines measures to prevent food safety problems and a program of regular testing.
Turbidity removal from pond waters
Troublesome turbidity in aquaculture pond water often results from clay or fine silt particles that remain suspended due to turbulence or sedimentation.
Contributions of marine aquaculture to sustainable development of island regions
Research is leading toward a methodology to assess the contribution of marine aquaculture through performance measurements and impacts.
Marine fish farming in Vietnam
While most marine aquaculture in Vietnam has been based on traditional small-scale cage operations in protected locations, the development of larger offshore cage systems could lead to industry expansion.
Water use at integrated aquaculture-agriculture farms
Fish farming in Egypt is not formally recognized as an agricultural activity, so aquaculture cannot use water from irrigation canals. However, fish are raised as primary or secondary crops in combination with fruit and other plant crops.
Seaweed aquaculture provides diversified products, key ecosystem functions, part 2
Seaweed remains a relatively untapped resource with potential as edible food, feed ingredients, cosmetics, agrichemicals, biomaterials and bioenergy molecules.
Seaweed aquaculture provides diversified products, key ecosystem functions, part 1
Seaweed plays key roles in Earth processes as a primary producer and link in the food webs of coastal and estuarine ecosystems.
Biofloc technology options for aquaculture
Biofloc technology offers advantages for the sustainable culture of shrimp and some species of fish.
The Fishery: One farm, one fish at a time
The Fishery is an inland farm in California that raises largemouth bass, carp, sturgeon and catfish in a recirculating system that minimizes water use.
COEXIST project addresses uses, interactions in Europe’s coastal waters
Throughout Europe, debate is taking place as to whether new fish farms, wind farms, tourist facilities or marine and/or coastal protected areas should be established. Competition for space is increasing. In the COEXIST project, partners from 10 European countries are exploring these developments, aiming to increase synergies and reduce conflicts, particularly with regard to the fields of aquaculture and fisheries.
