It is basically referred to rearing of sheep in fresh water. Fishing has long been an important source for human nutrition and commercial activity. Although most fishing occurs at sea, in the marine environment, many smaller-scale fisheries rely on inland bodies of water such as lakes and rivers.

Some inland fisheries are based upon fish farming, where species are raised in giant tanks or ponds.
