Farming of giant freshwater prawns is very popular in China. The Yangtze River Delta region produces more than 60 percent of the country's output. Production increases have resulted from a novel system that involves greenhouses that allow ponds to be
EWOS and Canadian researchers have developed a model to measure the ecological footprints of aquafeeds using ISO-compliant lifecycle analysis methodologies.
Early biofloc-based culture systems in tanks in Brazil have given way to commercial-scale bioreactors housed in greenhouses that utilize water fertilization regimes, high-protein feeds and salinity controls.
Although 16.6 million metric tons of carbon are annually buried in aquaculture ponds, estimated carbon emissions for culture species have approached several metric tons of carbon per metric ton of aquaculture product.
As an alternative to pond production, U.S. scientists have developed bio-secure greenhouse-enclosed raceways for intensive shrimp production with limited water exchange.
