| Abstract | Intensification of fish cultures has conventionally been related to increased water consumption per weight unit of fish. Scarcity of water in arid and temperate climates, as well as the rising awareness of national and international administrations to aquatic environment, may severely inhibit further development of intensive fish farming systems in which water is used to flush nutrient rich water from farms to the environment. A new intensive closed water culture system, actually being developed in Israel, seems capable of alleviating some of these ecologlcal problems by minimizing the quantity of effluents derived from freshwater fish farms. These systems which include a water reservoir, around which intensive follow-through ponds are constructed in commercial farms and research stations, have so far yielded 20 and 40kg m², respectively. The production potential of these systems depends very much on the natural biofiltration capacity of the reservoir, on close monitoring of water quality, and on implementation of optimal production plans. |
