Cage farming is simply raising fish in a large, submerged cage that can be used in a pond that otherwise might not be ideal for farming. An ideal location for a cage production farm would be in a pond/private lake that is too large for traditional pond aquaculture or is unsuitable for another reason (perhaps it is too deep, or cannot be drained). Cages can be floated throughout the pond and accessed either via a dock or boat.
