There is disclosed a fish farm (100, 100') having a rotatable cage net (120, 120'). A major operational cost is the maintenance of nets which have to be routinely cleared of fouling and reanti-fouled. This procedure has disadvantages, for example, it disturbs the stock, involves heavy handling, leads to abrasion of the net and involves substantial cost. Accordingly the present invention provides a fish farm (100, 100') comprising a structure (105, 105') forming a pool (110, 110') within which a cage net (120, 120') can be suspended, wherein the net (120, 120') forms a closed volume and there are provided means for rotating the net (120, 120') within the pool (110, 110') so as to orientate any selected portion of the net (120, 120') out of the water at any given time. |
