Farm construction

Size and depth: For operational convenience a minimum area of one hectare is widely accepted size of the farm. Depending on the local conditions the size may vary between half to 5 hectares. Though square farm is more economical, rectangular farms are more suitable for the harvesting. The constructed pond should have the capacity to hold at least 1.5 to 2 m water inside.

Dyke: The bottom of ponds needs to be sloped towards the drainage point or dyke.

Water supply and drainage: Appropriate water supply and drainage systems have to be designed for easy drain out the water from the pond. Ground water facilities is preferred for avoiding polluted water.
