Fish are generally at high density and artificial feed is supplied. Water quality is, however, maintained by natural currents and tides. 3). 2. Bivalve culture on racks or long-lines placed in the open water is an open system. 3 Example of aquaculture in combinations of different levels of culture intensity together with open, static, semi-closed and recirculating (closed) systems. Culture intensity System Extensive Semi-intensive Intensive Open Long-line culture of scallops, table oysters in mesh baskets Static (ponds) Carp polyculture in ponds , milkfish culture in lakes Mud crab culture in tidal ponds in mangroves X Enclosures within freshwater lakes for culturing fish, such as tilapia Freshwater fish polyculture with aeration Pond culture of shrimp at 20 animals/m2 X Seacage culture of fish, such as sea bream, sea bass, Atlantic salmon Saltwater crocodiles Semi-closed Closed Pond culture of shrimp at ca.
E. it may have some basic organic fertilisers, such as animal and plant wastes, but no aeration, etc. These systems usually have a low stocking density, generally <500 kg/ha, and the natural productivity of feed (plants and animals) within the system and natural gas exchange is sufficient to support the cultured organisms. g. bivalve and seaweed culture. Seaweed culture differs, of course, from animal culture in terms of food requirements, but the seaweeds are dependent on the culture environment for inorganic nutrients.
In some cases, the aquaculture animals (fish and freshwater crustaceans) are added to fields where the crop, typically rice, is grown partially submerged in water. The cultured animals feed on the plant waste materials and grow, and are harvested after the crop, when the field is drained. A double crop, plant and animal, is obtained from the field. Modern aquaculture in developed countries has disintegrated aquaculture. The move has been towards developing monoculture systems for high-value species with single use of water.
