A recent study evaluated the effects of a fishmeal-free diet on Atlantic salmon performance and fillet quality during successful growout to market-size in a commercial-scale, land-based, closed-containment system using water recirculation technology. Test fish performed well, with 97 percent survival
Although today’s soybeans offer many benefits, farmers can also plant alternatives, sometimes on the same farms that raise genetically modified beans. Organic beans meet specific market demands, and a conventionally bred non-GMO bean has been developed for use in aquafeeds
In targeting grouper for new and sustainable farming technology, the authors developed an oral vaccine to control nervous necrosis virus (NNV) infection at the larval stage and multivalent injective bacterial and viral vaccines for the grow-out stage.
After rapid expansion of glass eel culture in the mid-1990s was followed by overproduction, pricing problems, glass eel shortages and NGO pressures, European Union countries adopted national management plans for the eels. Importation of consumption eels was stopped, and exportation
Research is leading toward a methodology to assess the contribution of marine aquaculture through performance measurements and impacts.
Basic components of biosecurity include knowledge of diseases, adequate detection methods and the use of “clean” shrimp stocks.
Recent research is demonstrating that biofloc-based proteins are suitable replacements for fishmeal in aquaculture diets. Since bioflocs can be produced while treating aquaculture effluents, a waste product can be converted into a valuable resource.
The amount of fishmeal and fish oil used in aquaculture has remained static, while output from aquaculture has increased.
