| Recirculating Aquaculture Systems (RAS) may be considered an alternative to pond aquaculture technology (by consuming lower amounts of water producing similar yields of crop) or can be integrated in a sort of "production chain" with net pen systems. The interest in RAS is due to their intrinsic advantages like the reduction of land and water requirements, the high degree of environmental control allowing year-round growth at optimum rates and the possibility to produce in close proximity to markets. Moreover, the high level of control improves risk management linked with bacterial and parasitic infections and predator pests. Finally, waste production (both particulate and soluble) can be controlled and minimized contributing to make these systems... |
