STEP -BY - STEP IN POND CONSTRUCTION


RECOMMENDED STEP-BY-STEP POND CONSTRUCTION

Recommended pond standards are discussed below in relation to management and production potential and in accordance with Department of Fisheries and Allied Aquacultures, Auburn University, Alabama, USA.

         POND LEVELS (DYKES)

The pond’s sides are called levees or dykes. The pond levees should be well compacted and have a gentle slope. The greater the degree of compaction, the stronger the levees will be. Thus, during construction, one should lay down about 15 cm of soil which, when compacted will become about 10 cm high. There should be no stumps or debris left within the pond levees. Soil should be compacted shortly after it is laid to prevent hardening (some soil become rock-like if they are allowed to harden). The level of compaction achieved when constructing the pond levees affects pond management and production as follows:

a.                 Poorly compacted levees are weaker and often collapse during the course of production when wind pushes the water and causes waves to wash against the levees thus eroding them. When pond levees collapse during the course of production:

Ø The ponds become shallower which lowers the ponds’ carrying capacity.

Ø There is increased siltation and clay turbidity which have a negative effect on water quality for production.
