The extensive shrimp farming without water exchange in combination with Hat Sinh Hoc

Currently, the extensive shrimp farming model is considered as the most sustainable model compared to other models.

Recently, however, this model has been affected by many factors such as climate change and environmental pollution. In addition, it also was overwhelmed by intensive and super-intensive farming models. Besides, it is also affected by farmers’ abuse of chemicals in the farming process, pursuing profits, and applying new technologies that are unsuitable for the actual production model.

Therefore, the extensive farming model encountered many challenges and was ineffective compared to the traditional model.

To solve the problems, Binh Minh Aquaculture Development Co., Ltd. recommends that farmers’ culture according to the extensive shrimp farming model without water exchange in combination with Hat Sinh Hoc.

The model’s advantaged

• Unchanging the water helps limit pathogens from outside water sources. The water environment is also less changed during the farming process.
• Using Hat Sinh Hoc in ponds helps provide beneficial microorganisms, decompose organic matter, mineralize the pond bottom, release toxic gases and toxins accumulated in the soil for a long time. In addition, it also helps to create watercolor and natural foods such as worms, rice snails, and copepods. The food resource is produced continuously throughout the farming process.
• Shrimp grow fast, develop evenly, and reach a high survival rate.
• High profit and low cost
• High-quality shrimp and high-valuable

Recommends:

• Selecting quality, disease-free postlarvae from reputable hatcheries.
• Selecting highly adaptable and good disease-resistant postlarvae.
• Renovating and designing ponds according to technical procedures.
• Using Hat Sinh Hoc to create watercolor and natural food before 5-7 days stocking and periodically throughout the farming process (see instructions for use on the package).
• Checking and adjusting suitable pond environment factors before stocking.

Appropriate environmental indicators

• Stocking density is appropriate for each species

For black tiger shrimp: average 1 individual/m²

For white leg shrimp: average 5-6 individuals/m²

• You should design the nursery pond at the beginning of the crop when raising the next crop.
