The Department of Fishery, Faculty of Agriculture is carrying out the vannamei white shrimp farming project using a low-saline water circulation system. The project is the collaboration between the department and Thai Union Feed Mill, Public Company. A sustainable white shrimp farming system requires circulation of water and draining sewage and wastes in the pond. The waste from shrimps can be used as fish feeds, while the water is being circulated and treated in a closed system in order to reduce discharge of water from the system. The density is 4-5 times higher than earth-pond farming. The length of time for one batch is 70 days, when the production is 60 shrimps per one kilogram.
Khun Kamphon Thaiso, the manager of the Fishery Unit of the Faculty of Agriculture, Khon Kaen University, revealed that the vannamei white shrimp is the sea shrimp that is of economic important value at present. The shrimp has been developed until it can be farmed in fresh water with low salinity, using a circulation system of water. During the farming batch, there is no discharge of water, so it is environmental friendly. The capacity of this farming is 300 shrimps per one square meter. The period of one batch is 70 days, to obtain 60 shrimps per 1 kilogram.
The research outcome can be used to promote farmers all over the country to raise shrimps in fresh water using the water circulation system. It is a sustainable occupation for farmers. Any farmer who wants more details of the farming system can contact the Faculty of Agriculture, Khon Kaen University at Tel. 043 202 360.
