CATFISH FARMING IN NIGERIA

The re-circulating aquaculture system are designed to provide a controlled environment that optimizes the growth of fish (or other aquaculture species) while conserving water water resources. This system works effectively if they accomplish the following:
* Aeration, that is oxygen for fish and bio-filter.
* Removal of particulate matter.
* Biological filteration to remove waste (NH3 and NO2)
* Buffering of PH.
The recirculating aquaculture system has a number of advantages over other culture systems. This include:
* Reduction in all over water usage and land requirements.
* Improving control of many aspects of nutrition
* Water quality monitoring.
* High degree of environmetal control allowing year round growth at optimum rates.
* Feasibility of locating in close proximity to prime markets.
* High stocking rates.
The culture system equally poses a number of challanges because of its peculiarity. These problem include:
* High energy demand.
* Unstable water quality compared to ponds and flow-through due to high stocking densities, build up of sediment and pathogens, slower turnover of water, and the continues of flow of water throughout the system which can spread pathogens rapidly.
* In adequacy of trained and experienced personel.
The system comprises of the following:
= Fish culture tank.
= Water treatment tank.
= Sediment basin.
= Bio filter.
= clean basine.
= Packed column aerator.
