7 Steps How to Cultivate Windu Shrimp, Easy and Profitable
Shrimp is one of the most important fishery export commodities in Indonesia. Types of shrimp that are widely cultivated are vaname shrimp and tiger shrimp. Tiger shrimp itself is a native shrimp from Indonesia. Tiger shrimp, also known as black tiger shrimp, has a body size of 35 cm and a weight of about 260 grams. The selling price is slightly higher than vaname shrimp, so many people cultivate tiger prawns.

Tiger shrimp has the Latin name Panaeus monodon. This native Indonesian shrimp has body characteristics in the form of a bluish green color, hard body skin, and has large stripes like a tiger. The habitat of adult tiger prawns is in the middle of the deep sea, while before adulthood, tiger prawns live in shallow water or on the coast.
The cultivation of tiger prawns itself is arguably quite difficult than the cultivation of vaname shrimp from America. Because this variety is susceptible to white spot disease. However, tiger shrimp farming has bright prospects in the future. Of course, for cultivation to be successful and profitable, it takes perseverance and knowledge of tiger shrimp habits and proper cultivation techniques. How to cultivate tiger prawns can be listened to in full below.
Complete Steps for Cultivating Tiger Shrimp
Tiger shrimp is a variety of shrimp native to Indonesia whose natural habitat is in sea water or in brackish water. However, this variety of shrimp can also be cultivated in fresh water. Tiger prawns are cultivated in ponds, unfortunately the harvest cannot have the same body length and weight as tiger prawns in the sea.
1. Preparing the Pond
The first step in tiger prawn farming is to prepare the pond. The preparation of the pond itself begins with site selection. Locations that are very supportive for the breeding of tiger prawns are in brackish water conditions, therefore it is advisable to choose a location that has abundant brackish water resources, including near the coast.
In addition, the selection of cultivation sites should pay attention to the following:
The selected area is along the coast, or at least a few meters from the beach sea level, with an average temperature of 26 to 32 degrees Celsius.
Sandy clay texture with a sand content of less than 20%, but the sand is easily compacted so it can hold water.
The environment and water around the pond location must be good enough so that tiger prawns can produce a bountiful harvest.
Embankments must be built strong, solid, not leaking and can withstand water erosion.
The water used for cultivation is brackish water with a salinity of 15 to 35 ppt, a minimum dissolved oxygen content of 3 ppm, a pH of about 7.5 to 8.5 and the water must be free from pollution.
After the right location has been obtained, the next step is to create a cultivation pond. The following are important things to consider when making a pond:
Prepare the necessary tools, including measuring devices to ensure water quality and temperature.
The ponds made are 3 ponds. Namely nursery ponds, log ponds, and enlargement ponds. Each plus has its own sluice, faucet and gutter for the process of draining water. Build a bund with a height of 50 cm above the water surface around the pond with a width of 2 m, and also build a bund to separate each pond.
Ponds are made side by side with different heights. Make 1 canal in the highest pond, and 1 canal in the lowest pond to drain water. Create sluice gates between ponds 1 & 2, as well as between ponds 2 and 3 to facilitate the regulation of water circulation in aquaculture ponds.
2. Cultivating the Land
Before filling the pond with water, do the land preparation first by removing the mud with a hoe or sucking it up with a water pump. Then do the reversal of the soil at the bottom of the pond with a hoe or plowed to free it from toxic gases and ammonia. Also do liming to neutralize soil acidity. The dosage is 1 ton/ha. Then do the drying to the ground to kill germs.
3. Adding Water
The land is left for 3 days before the pond is filled with water. The introduction of water is done gradually, first fill it up to a height of 10-25 cm, leave it for a few days so that the plankton seeds grow. Then the water is added again to a minimum of 80 cm.
4. Selection of Seeds
Tiger prawns or fry can be purchased at hatcheries. Choose fry that have a high level of endurance, are active in movement, are physically firm in color, are healthy, have complete body equipment and are resistant to adaptation to environmental changes.
The fry must be tested by placing them in a basin, adding water, then stirring the water vigorously for 1-3 minutes. Choose fry that remain actively moving after the spinning water stops. Seeds that are the same size are selected, both post larval seeds or large or juvenile seeds.
5. Spreading Seeds
The fry were stocked after the plankton had grown, indicated by the water brightness of less than 30-40 cm. The seed is sown in the morning or evening. Spreading seeds should be done gradually. Starting from soaking the plastic fry container for 15-30 minutes in the pond. After that, the plastic is opened and folded at the ends, leaving it afloat for 15-30 minutes for air adaptation.
Next, sprinkle the pond water on the plastic for 10 minutes, so that the water and fry mix can adapt to the salinity of the pond water. Furthermore, the fry can be removed by allowing the seeds to come out by themselves.
6. Maintenance
After that, what is done is maintenance and feeding. Maintenance that must be carried out includes:
Pay attention to water quality to keep it stable by adding or changing water carefully.
Fertilize to encourage the growth of natural food. The fertilizers used are manure 250gram/m2, TSP 5gram/m2, and urea 5gram/m2.
The feed can be in the form of natural food from the shrimp itself or plankton and decaying plant and animal remains in the pond. Tiger prawns that are starting to mature will eat soft animal meat such as oyster shells.
Provide additional feed when the maintenance period is 3 months, in the form of a mixture of fine bran with chopped trash fish, snails, crabs, snails, crustaceans.
Pellets are given for the enlargement process. Given as much as 4-6 times a day with a dose of 15-20% of the total body weight of the fry. For adults, give 5-10% of body weight per day.
Prevention of pests and diseases.
7. Harvesting SHRIMP
Tiger prawns are harvested at the age of about 5-6 months, with an average weight of 8 ounces per head. Harvesting is done in the evening or early morning by spreading nets. This is an explanation of the steps for cultivating tiger prawns. Hope it is useful.
