Under high-tech farming models which use super-intensive farming, the beds ofshrimp breeding ponds are covered with plastic sheets and anti-sunlight netsare hung above. The models are also equipped with oxygen-generating facilities.
Besides shrimp breeding ponds, other ponds filter water which is released intoshrimp breeding ponds or used for treatment of waste water.
High-tech shrimp farming has a success rate of 90 percent and offers far higherprofit than traditional shrimp breeding in mud ponds, according to farmers.
Bui The Vuong began using advanced farming techniques to breed shrimp on a 7hafarming area in Long Dien district’s An Ngai commune last year.
In the 7ha area, he uses 1.5ha for shrimp breeding ponds and the rest for pondsto filter water and to treat waste water.
High-tech shrimp farming can produce three shrimp crops a year, up nearly twotimes against traditional farming models, Vuong said.
The death rate of shrimp bred in high-tech shrimp farming is significantlylower compared to traditional farming models.
He has bred five shrimp crops under the model and earns about 1.2-1.4 billion VND(51,000-60,400 USD) each crop.
Similarly, Le Quang Hung, one of salt farmers in Ba Ria city’s Ward 12, is applyinghigh-tech shrimp farming.
He switched from salt making to black-tiger shrimp breeding in 2005, and thenlater switched completely to breeding shrimp.
In 2018, he invested 1 billion VND (43,000 USD) in high-tech shrimp farming forhis 1.5ha. He built two ponds for breeding shrimp and three ponds for treatingwater, and bought oxygen-generating facilities, plastic sheets andanti-sunlight nets for shrimp ponds.
He now breeds three shrimp crops a year with an output of more than 16 tonnesof shrimp a year, earning a profit of nearly 1 billion VND a year.
The province has about 352ha of shrimp bred under high-tech shrimp farming, upnearly 100ha against a year ago, according to the province’s FisheriesSub-department.
Under high-tech shrimp farming, shrimp can be bred at a density of 250-500shrimps per sq.m. Water used for breeding shrimp is closely managed and is notaffected by weather conditions, so shrimp can be bred year round.
Nguyen Huu Thi, head of the sub-department’s Aquaculture Management Division,said the high-tech shrimp farming models in the province have had positiveresults and helped shrimp breeders cope with climate change.
High-tech shrimp farming has also improved production efficiency since shrimpare bred at a high density, he said.
To encourage more farmers to apply high-tech farming, the division isorganising courses on advanced farming techniques to help farmers make theswitch from traditional shrimp farming./.
