Ordinary earthen embankments are constructed for extensive ponds and pre-stressed rein forced cement concrete ponds are constructed for intensive and super intensive culture practices. The best time period to construct the ponds is in between late winter and early summer season. Construction process requires careful supervision and skilled workmanship as the success of entire project depending upon the efficient construction.

Following are the sequences of operations to be carried out in the process of construction.

• Survey of the site
• Land clearing
• Land making
• Excavation
• Construction of drainage system
• Construction of dykes and sluices
