• Re-circulating aquaculture systems are indoor, tank-based systems in which fish are grown at high density under controlled environmental conditions.
• These systems can be used where suitable land or water is limited, or where environmental conditions are not ideal for the species being cultured.
• This type of aquaculture production system can also be practiced in marine environments.

PROBLEM STATEMENT AND PROBLEM ANALYSIS

• A tremendous increase in the Kenyan population with a direct proportion in demand for protein-rich food.
• The higher cost of protein-rich food in the country due to higher demand and limited supply.
• High pollution in ponds, rivers and lakes.
• High concentration of ammonia causes lethal stress to fish.
