Stages of starting giant prawns are:
1. LOCATION OF CULTIVATION
The development planning of the cultivation container shall fulfill the requirements, among others; flood-free areas and pollution, sandy clay type, ponds made at an altitude of 0-700 meters above sea level.
Water is available year-round, pollution-free, water circulation must be good, pollution-free, pollution-free. The recommended water debit is 0.5-1 liters per second for the 300-1,000 m2 pool area.
2. MATERIALS AND EQUIPMENTS
As in pond cultivation in general, commonly used equipment, among others; seed carrier, bucket, bucket, sack, scales, smooth sieve of cloth, hoe.
3. WATER MANAGEMENT
Good water circulation plays an important role in the implementation of giant prawns enlargement. Should water in the pond must flow. For maintenance pools with non-flowing media water quality tends to decrease after one month of maintenance. To overcome it can be done replacement of water as much as 30-50% with new water.
C, with a pH of 6.5 to 8.5. Oxygen The optimum temperature required is 28-30 minimum dissolved is 4 ppm, required also Ca at least 52 ppm and salinity 0-5 ppt.
4. PREVENTION OF HAMA AND DISEASE
The existence of pests and diseases is determined by visual examination of the disruptive organisms both predators and competitors.

In the process of enlargement required medical examination performed as follows:
Sampling for prawn health testing (Macrobrachium rosenbergii) was done randomly with the number of shrimp in accordance with the need for visual or microscopic observation.
