Construction a pond

Ponds must be established according to the landscape available.
A rectangular pond is easier for monitoring fish feeding rate, drainage, harvesting as well as cleaning the bottom of the pond.
Dike of the pond must be built based on soil type, rainfall situation of the region, heighted needed to avoid floods.
The crest of the dike must be built to be convenient to monitor fish and feeding, and harvest between the ponds.
The slope of the dike must be constructed to ensure to resist flooding and waves.
Toe must be built from the base of the dike to the inner slope for reducing soil erosion from the slope.
The bottom of the pond must incline no more than 2% to the drainage.
Male mono-sex culture can be raised well even in 0.03-acre pond.
The optimum water depth is 1.5 meter and measuring pole should be placed in the pond before filling water to easily determine the water depth.
Build 3-meter bamboo or wooden bridge in the pond to feed the fish.
The water inlet and outlet must be separate and thick PVC pipes with the diameter of 3-4 inches are appropriate for inlet and outlet.
Fence should be built to prevent poaching and entering wild fish to the pond.
