Introduction: Composite fish culture of six species comprising three Indian major carps
and three exotic carps can be successfully carried out up to an altitude
where average annual temperature of water do not fall lower than 20 °C. The
species composition for the lower temperature (below 20 °C) should be the

Application of lime at the
rate of 3,000 kg/ha in one installment preferably on the bottom soil when
the pond is dry. Lime may also be applied on the water.
After 15 days of accumulation of water if lime was added on the bottom soil
or after 15 days of application of lime on the water, cow-dung may be applied at the rate of
10,000 kg/ha in one installment. After 20 days of application of cow-dung,
the pond should be stocked with fingerlings.

application of each installment of cow-dung.
