Advantages of Cage Culture farming
Resource use flexibility Cage culture can be established in
any suitable body of water, including lakes, ponds, mining pits, streams or
rivers with proper water quality, access and legal authority. This flexibility
makes it possible to exploit underused water resources to produce fish
Low initial investment :Relative to the cost of pond
construction and its associated infrastructure (electricity, roads, water
wells, etc.), cage culture in an existing body of water can be inexpensive. At
low densities (relative to pond surface acreage) cages often do not require
aeration or any electrical source. Cage materials are not especially expensive
and many kinds of cages can be constructed with little experience.
Simplified cultural practices: Cages lend themselves to
straightforward observation of the fish. The observation of fish behavior, especially
feeding behavior, is critical to anticipating and avoiding problems with stress
and diseases, which often occur in cage culture.
Simplified harvesting
:Cages are usually harvested by moving them into shallow water, crowding the
fish into a restricted area, and simply dipping the fish out of the cage. Or,
the cage can be lifted partially out of the water so that the fish are crowded
into a smaller volume, and then the fish dipped out. This makes it possible to
partially harvest fish from cages as needed for local niche markets or personal
consumption.
Multi-use of water resources :The confinement of fish in
cages should not hinder other uses of the water resource, such as fishing,
boating, swimming, irrigation or livestock watering.
