Project Background:

Currently, the Whiteleg Shrimp aquaculture is in the open air. Therefore, over the years, it has not been possible to regulate the environment positively for shrimp. Shrimp aquaculture is water-intensive, as the water needs to change constantly during the farming process. This helps eliminate ammonia and nitrite that are excreted by shrimp farming. Another key issue is that the space available for shrimp aquaculture is limited. It is impossible to expand due to environmental impacts, particularly to mangrove forests.

Performance:

The aquaculture business now applies technology from Israel for closed-aquaculture. This approach helps prevent disease and regulate optimum temperature for shrimp aquaculture. The Bio-floc System is deployed to treat excretion in the water generated during the farming process. Therefore, this process requires less water compared to its outdoors counterpart. The treatment technology, or Bio-floc system, during shrimp farming eliminates the need to change the water. The Bio-floc System uses microorganisms as an agent to treat the shrimp aquaculture. The system has the production capacity of 13-14 tons/Rai/batch. It requires only 700 liters/1 kg of shrimp production. There is no damage to the shrimp from ammonia or nitrite toxicity. On the other hand, a typical shrimp aquaculture requires 5,000- 6,000 litres/1 kg of shrimp production. To stimulate the Bio-floc System at the shrimp farms, a starter culture of microorganisms is required. It takes only 10-20 days. The system can treat nitrogen solvent as well. It is a new innovation, and the patent is currently being processed.
