Shrimp farming in cement tanks

The model has brought farmers a high economic efficiency. This is a high-tech farming model, reaching 95% success rate, and opening a new direction in the shrimp farming industry.


To implement shrimp farming in cement tanks, it is necessary to meet the following issues: Technical facilities must be fully equipped: There are 3-phase electrical systems and standby generators, fan and oxygen systems bottom, siphon system …; Human resources with high management skills, technical know-how and measuring equipment, to control the environment and pathogens. Source of inputs such as seed, feed, microbiological quality products and are strictly controlled.


Suitable environment for white shrimp: Water temperature 20 – 300C; salinity 5 – 30 ‰, preferably 10 – 25 ‰; pH 7.5 – 8; dissolved oxygen 4 mg / l,> 2 mg / l; transparency of 30-50 cm; Green water, green bean shell or ripe plum. Sufficient source of salt water and drainage is required.

System design

The system of vannamei farming in cement tanks consists of 2 indoor cement tanks with a covered area of ​​100 m2 / tank, the water level is maintained at 1 m; Level 2 pond system consists of 4 floating ponds lined with canvas completely outdoors, in which there are 2 ponds with area of ​​500 m2 / pond and 2 ponds with area of ​​1,000 m2 / pond. In addition, shrimp farms are also equipped with 8 machines to push water mixed with gas and 4 machines to feed shrimp automatically.

Shrimp ponds are designed to be 25 – 40 m2 wide, over 1m tall; Stocking density is from 220 to 250 individuals / m2. With a 40 m2 tank, about 1,000 shrimp will be stocked. In the aquarium is installed separate aeration, drainage system separately. Before stocking, proceed to supply water about 50-60 cm and use TCCA to thoroughly disinfect the aquarium, remove all water and wash out after 3 days.

Choose varieties

Choose uniform shrimp, bright shrimp color, homogeneous, pigment is clearly shown; Choose to breed shrimp from reputable and brand-name production establishments, have broodstock quality ensured according to regulations; must check some specific diseases such as MBV, white spot, yellow head, taura, hepatopancreatic necrosis … (with quarantine). Before stocking, shocking should be carried out to remove weak shrimp after transporting shrimp seed to ponds before stocking. Formol shock: drop 100-200 shrimp seed into a glass cup or cup of 100 ppm formol solution, monitor for 30 minutes, if the mortality rate is below 5%, it is satisfactory.


Currently, people have completed the farming system in 2 stages, in which:

Phase 1: From the time of stocking shrimps to about 30 days old, the shrimps are raised in a covered cement tank with an area of ​​100 m2 / tank. Shrimp are stocked with a density of 1,000 fish / m2, when shrimp reach the size of 900 – 1,000 fish / kg, it will be brought to phase 2.

Note, when the shrimps need to check the health of shrimps carefully, the shrimps are healthy, not in the molting cycle, the shell is strong, the shrimps are not bent, body stems when lifting the ready to eat … If the weak shrimp should not be by handcraft such as fishing nets, trawling … it is best to maintain shrimp for a few days, adding minerals, beta glucan, Vitamin C to help the shrimps grow and then carry out shrimp farming.

Phase 2: 30 days old shrimp will be pulled to drop into 4 outdoor floating ponds, including 2 ponds of 1,000 m2 and 2 ponds of 500 m2 area until harvest. Shrimp are grown at a density of 60 individuals / m2, after 65-70 days of raising ponds with a yield of 1 ton / 1,000 m2 (10 tons / ha), the size of shrimp is about 55 shrimp / kg.

Feeding: Food is used to ensure quality. Every day, monitoring the feeding activities of shrimp, the ability to catch prey, environmental conditions to adjust the amount of food appropriately, chemical treatment, water change instead of water. Periodically supplement minerals, vitamins, digestive enzymes to feed to enhance resistance for shrimps.
