Water recirculating aquaculture systems: management by-pass and trouble shooting

Water Recirculating Aquaculture system (WRAS) as a culture system can be simply configured to combine both mechanical and biological filteration mechanism. This system can be regarded as a fish factory being an intensive culture technology system with high-density stocking and carrying capacity. Recirculating systems has some production advantages over other culture systems especially in intensive production. This production system achieves good and stable water quality management and enables the farm manager to trouble shoot as management protocol is easier to determine in a more business manner. Challenges in running this system in Nigeria include poor design, irregular power supply alter failure, high cost of quality feed, poor water quality management and high cost of water quality kits. Similarly, unavoidable continuous daily stress on fish stocked, low biosecurity understanding and lack of expertise coupled with inadequate financing are common issues in running this system. Therefore, necessary by-pass protocols become necessary in the management of this system in Nigeria for profitable production.
