6.1.2.1.Culture techniquesPreparation of the site
Can be cultured on a vegetable field 700-1000m2, with 10-13 cm top mud. Clear the weeds on a 30 cm bund and sun dry so as to kill other eggs. Spread poultry manure evenly @1200-1500kg/1000m2.Fill with water upto 12 cm. Adults lay eggs at edge of the pond after 8-10 days they hatch to 0.3cm larvae. One cycle consists of 50 day culture. A week before harvest weedicide (mild) and tea seed cake and algal stimulator is used. Water exchange is done to one third.
Harvesting
Starts after 20-25 days at temperature of 25oC. Lower temperature causes slow growth in 30-40 days. Harvesting is done in the morning to avoid high temperature.
