Pond preparation involves making ponds weed and predator-free and generating adequate natural food to ensure high rates of survival and good growth and thereby yields.

Ponds are stocked with seed of appropriate size after acclimatizing them to the new habitat when it is ready after fertilization.

Fertilization: The ponds are classified into three groups based on the nutrient levels of the soil substratum. Fertilization measures for carp production ponds are recommended as follows. While 20-25% of the total amount of organic manures is applied as basal dose, a fortnight before the stocking, the remaining amount is applied in equal installments on a bimonthly basis.
