HCM City (VNS/VNA) - Farmers in the Mekong Delta have had a bumperharvest of giant river prawns at good prices because of favourable weatherconditions and high market demand.

Under a special cultivation model, farmers breed the giant prawn and grow riceon the same field without using chemicals. The prawns eat natural food in therice fields.  

In Soc Trang province, shrimp–rice farmers are now entering the peak harvestseason.

Le Viet Thang, who has a one-hectare rice field in Soc Trang’s Phuoc LongDistrict, said he had a rice yield of seven tonnes per hectare, higher than inthe past.

The profit from harvesting prawn and rice this year was about 50 million VND (2,150USD) per hectare, he said.

Tran Van An, Deputy Chairman of the Phuoc Long district People’s Committee,said the rainy season ended late, so there was enough freshwater for the ricefields.

Local farmers used quality seeds and followed proper plant scheduling, whichhelped to increase yields.

The environmentally friendly shrimp – rice model reduces production costs,increases yield and profit.

In the rainy season, Bac Lieu has nearly 36,000ha of fields allocated for theshrimp – rice farming model, up nearly 3,000ha against the previous rainyseason.

Of the figure, farmers have harvested more than 20,000ha so far.

The cultivation model has an average prawn yield of 250 – 300kg per hectare percrop and 4 – 4.5 tonnes of rice per hectare per crop, according to Bac Lieu authorities.

In Ca Mau province, farmers in Thoi Binh district, which is the province’slargest giant river prawn producer, has about 12,000ha of giant river prawn –rice farming fields.

Nguyen Huu Canh, who lives in Tan Bang commune’s Kenh 6 hamlet in Thoi Binh,  has harvested giant river prawns in hisone-hectare rice field and earned a profit of 20 million VND (862 USD).

He began to release about 20,000 giant river prawn fry into rice fields in Junethis year and harvested about 250kg of giant river prawns after breeding forsix months, he said.

Huynh Van Dung, head of the Kenh 6 Hamlet Farmers Association, said: “The modelhas high economic efficiency, is easy to implement and is sustainable, so manyfarmers have done it.”

Farmers buy giant river prawn fry in Ca Mau and other provinces such as AnGiang province and Can Tho city for breeding, he said.

Traders buy the market-size giant river prawns at a price of 100,000 – 130,000 VND(4.3 – 5.6 USD) a kilogramme.

The price may increase significantly near Tet (Lunar New Year), which falls onFebruary 5 this year, according to traders.

In Tra Vinh province, farmers began harvesting giant river prawns in ricefields early this month.

Chau Thanh, Cau Ngang, Tra Cu and Duyen Hai districts and Duyen Hai town are TraVinh’s major giant river prawn breeding areas.

Chau Thanh has more than 1,100ha of rice fields in which farmers breed all malegiant river prawns, the largest in the province.

Nguyen Thanh Thuong, Deputy Chairman of the Long Hoa communal People’sCommittee in Chau Thanh, said this is the sixth year that many farmers in thecommune have bred giant river prawn and organic rice on one field.

Many aquaculture farmers have also switched from breeding two black-tigershrimp crops a year to one black-tiger shrimp crop and one giant river prawncrop a year, he said.

Investors who produce shrimp seeds, including male giant river prawn seeds, cantake advantage of the province’s preferential policies.

The model of breeding all male giant river prawns yields a higher profit thanthat of breeding mixed gender giant river prawns. The former has a highersurvival and growth rate.-VNS/VNA

Vietnam to diversify markets for agricultural products amid global trade shifts

According to the Ministry of Agriculture and Environment (MAE), Vietnam’s agricultural product exports are inevitably affected by disruptions in global supply chains and the imposition of unilateral, stringent tariff policies by major economies. Nonetheless, these challenges also present an opportunity for Vietnam to adjust its export strategy and focus more intently on emerging and high-potential markets.
