Chikoko pond is a pond made from a dark grey or dark brown or black fibrous clay material which is sometimes normally characterise with foul odour. This clay soil which is sometimes refer to as Nigerian deltaic clay, is one of the three types of soil found in the Brackish Water Mangrove Swamps of the Niger-delta region of Nigeria (fig:1a -brackish mangrove swamps).
Because of the firm and fibrous nature of this beautiful soil (chikoko soil)-see fig 1b.
Aquaculture specialist like me, have grab the opportunity that nature has given to us by converting this wonderful material into economic use for the construction of fish ponds which in return add value to the region food security, gross domestic product (GDP), job creation/wealth creation.
MATERIALS NEEDED FOR THE CONSTRUCTION
- Chikoko soil (fig;1b)
- Chikoko block Moulder (fig:1c)
- Head pan
It takes 4 work men to construct 20m2 chikoko pond for 3days because of the tide.
Chikoko pond just like any other ideal pond, have outlet/inlet, harvesting basin, dyke, excess water spillage. See fig: 1e & 1f, below.
The above pond is some of our cluster chikoko pond located at Egbokodo, Warri, Delta state, Nigeria.
The source of water for these pond is from the estuarine, the brackish water level rises and decreases every 6 hours, when the tide is high the water level can increase up to about 3m or more. Harvesting is done when the tide is low. It is cheaper to construct when compare to concrete pond/earthen pond, also easy to manage when compare to the management of other fish farming system.
