Aquaculture is the farming of fish, shrimp, and algae, and other seafood. Aquaculture supplies fish, such as catfish, salmon, and trout. Aquaculture was developed a long time ago in China and aquaculture supplies over 20% of all the seafood harvested.
Fish farming has been practiced, in some parts of the world, for hundreds of years. Today, half of the seafood eaten in the U.S. is farmed. To help meet the growing global demand for seafood, aquaculture is growing fast.
The environmental impact of fish farming varies widely, depending on the species being farmed, the methods used and where the farm is located. When good practices are used, it's possible to farm seafood in a way that has very little impact to the environment. Such operations limit habitat damage, disease, escapes of farmed fish and the use of wild fish as feed.
