GENERAL INFORMATION

Vietnam, with a coastline of over 3,260 kilometers (km) and more than 3,000 islands and islets scattered offshore, plus up to 2,860 rivers and estuaries, has been geographically endowed with ideal conditions for the thriving fishery sector which currently exists.

Great potential of fishery sector in Vietnam is embedded in water bodies of 1.700.000 ha in which 811.700 ha freshwater, 635.400 ha brackish waters and 125.700 ha coves and 300.000 - 400.000 ha wetland areas might be employed for aquaculture development.

The Mekong River Delta in the south and the Red River Delta in the north have been used for wild catch fishing as well as extensive fish farming.

Shrimp and pangasius mostly farmed in the Mekong River Delta, in which, shrimp farmes located in coastal provinces such as Tra Vinh, Bac Lieu, Soc Trang, Ca Mau, Kien Giang, Ben Tre..

Pangasius farming is developing in many provinces in Mekong River Delta such as Can Tho, Vinh Long, Tien Giang, An Giang, Dong Thap, Soc Trang, Hau Giang, Tra Vinh....

Production in the fishery sector grew at an average rate of 7.05% from 1991 to 2000, and 10% from 2001 to now. The country produces annually over 6 million MT of fish, in which its landings reached 2.7 million MT and aquaculture reached 3.3 million MT. In 2015, total fisheries production reached 6.56 million MT, including 3.03 million tons from catching and 3.53 million tons from aquaculture.

Ca Mau dense shrimp farming area expanded

The area of super-intensive shrimp farming in Ca Mau province, the country’s largest shrimp producer, has increased this year as the model offers high profits for farmers.

The southernmost province has about 857 ha of shrimp under the super-intensive farming model, up 175 ha from the end of last year, according to the province’s Department of Agriculture and Rural Development.

The model is called super-intensive farming because the density of shrimp is more than 150 shrimp per sq.m, three times higher than traditional farming.

The average output under the super-intensive farming model is 40-50 tonnes per ha of breeding crop. Some households have a yield of 80-100 tonnes per ha of breeding crop.

Nguyen Van Tuan, who breeds 2,000 sq.m of shrimp under the super-intensive farming model in Phu Tan district’s Phu Thuan commune, said his family harvested about 9 tonnes of shrimp per 1,000 sq.m in the last shrimp crop after three months of breeding. 

With a selling price of 160,000 VND (7 USD) a kilo, his family earned a profit of hundreds of millions of VND, he said.

If farmers implement the farming techniques properly, the super-intensive farming model offers high profits, he said.

Under the model, shrimp ponds are covered with net houses and plastic sheets in pond beds. The ponds are installed with fans at the pond surface and airlift pumps in the pond beds to provide oxygen for the shrimp.

Phu Tan, which has one of largest areas of super-intensive shrimp farming in the province, has 117 households with about 200 ha of shrimp under the super-intensive farming.

Mai Huu Chinh, director of the Ca Mau Department of Planning and Investment, said the output of super-intensive shrimp farming has contributed a large part in the province’s shrimp output growth this year.

The province has harvested more than 113,000 tonnes of shrimp bred under various models in the first nine months of the year, up 6.9 percent  against the same period last year.

Many shrimp farmers in Ca Mau have cooperated with companies to breed shrimp under the super-intensive farming model.

Under the cooperation, companies will provide farmers loans, farming techniques, and material input for breeding shrimp and buying harvested shrimp for farmers.

Nguyen Van Dung, who previously bred shrimp under an industrial farming model in Ca Mau city’s Hoa Tan commune, said he cooperated with a company to breed shrimp under the super-intensive model over the past year and got good results.

As of August, Ca Mau has eight co-operatives and one co-operative team, which have signed cooperation contracts with 8 companies, according to the province’s Department of Agriculture and Rural Development.

Nguyen Tien Hai, chairman of the provincial People’s Committee, has ordered relevant departments and agencies to carry out synchronous measures to prevent environmental pollution in super-intensive shrimp farming.

Chau Cong Bang, deputy director of the province’s Department of Agriculture and Rural Development, said the province is drafting regulations for intensive and super-intensive shrimp farming in the province.

Under the draft regulations, administrative fines for violations of environmental protection related to intensive and super-intensive shrimp farming could be 3-100 million VND (130 - 4,400 USD), he said.
