Introduction to aquaculture

Sea prawn farming may be a lucrative business but the project requires a large track of land, access to sea water and sea water piping for irrigation and waste water management. Generally there are three stages involving the use of sea water. First, sea water has to be pumped into a retention pond with compartments for sediment to settle and to filter off impurities. Next, the treated sea water is transferred into breeding ponds which are usually divided into smaller cells of half a hectare in size. Finally, the waste water from each cell has to be treated before being discharged into the river or before being re-used.
