What kind of freshwater shrimp is this one (prawns) does have a large enough potential, so it can generate profits doubled. Evidenced from the demand for prawns both in the country and from abroad are increasing. Prawns are one of the best freshwater commodities of the future because in addition to higher selling prices than other freshwater fish can also be marketed for domestic and foreign needs, this is characterized by demand for exports to various countries such as Japan and some countries in Europe . In other words, giant prawns have high economic value and potentially benefit if developed.
Cultivation of giant prawns can be done in ponds or land ponds. Currently, the enlargement of prawns has expanded to various regions, including West Java, Central Java, East Java and Bali. To support the success of the activities / cultivation of the business is required technology in accordance with the needs and scale of business owned by the cultivators.
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.
Pests that often interfere with the pond maintenance is the wild fish that enter without accident like fish cork, catfish and others. To prevent the entry of the predator pests need to be made a filter on the entrance and discharge of pond water in the form of hapa made of nets with mesh size 0.2 mm.
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.
Visual observations were performed for examination of symptoms of disease and perfection of giant prawn morphology (Macrobrachium rosenbergii).
Microscopic observations were performed for examination of pathogens (parasites, fungi, viruses and bacteria) in the laboratory.
5. THE SHRIMP OF THE SHRIMP
Prawns can be harvested after 4 months, 6 months, or even more, according to the shrimp size required by the consumer. Usually giant prawns can go on sale after reaching the size of 20 - 25 grams / tail, but the greater the size of shrimp is also more expensive.
So some practical prawns cultivation of prawns, stages of prawns cultivation, as well as a picture of the advantages of cultivation of giant prawns. Hope can inspire and be useful.
