Rotating Fish Cages to prevent Fouling
November 16th, 2008 by Morten Nilaus
Another way of preventing fouling and Easy cleaning is to use rotating fish cages.
Rotating Fishcages; when one side of the cage is being fouled up, it rotates and let another side handle the flow of water; this should help prevent or at least diminish the fouling process considerably. The turning of the cage should be done by a buoyancy system, where air is let into one side of the cage to turn it so that a new side is facing the current and gets cleaned.

Almost all marine cages are faced with the serious problem of biofouling. In tropical waters, the rate of fouling is very much faster than in subtropical or temperate regions. The rate of fouling depends on the mesh size of the nets, temperature of the water and productivity of the site.In recent years, rotating net-cages have been suggested. However, their applicability in rich tropical waters has yet to be tested.Hence as has been mentioned about rotating cages is true, but tropical regions may have different circumstances and the rotating cages may not be very effective then.
