Salmon farming in Vietnam

Last update: 23:21 | 14/05/2017

Hoang Van Ta, 53, was the first person to farm salmon in his commune in the mountainous province of Lang Son in 2007 and now he earns as much as 4-5 billion VND (180,000-220,000 USD) a year from salmon.

Mau Son Commune, Loc Binh district is located about 170km northeast of Hanoi, with the highest peak reaching about 1,600 metres above sea level. The area is a famous tourism site for its spectacular landscape, its tea from tea buds plucked from the mountain’s vast tea fields, and now, for its delicious salmon, as well.

In 2007, when Ta traveled to Sa Pa district and had a chance to visit a salmon farm there, he thought of building the same farm in Mau Son commune, where the weather conditions are similar.

He invested 1 billion VND (44,000 USD) in building artificial pools, pumping machines, and salmon breeding. But the beginning was hard. Ta had to travel back and forth from Mau Son to Sapa for seven months to learn from the experience of veteran salmon farm owners. “Breeding salmon is like baby-sitting. It doesn’t mean success even if you’ve learned by heart all the theories,” Ta said.

Initially, his salmon died after a short time. “Salmon can only survive in clean water and in temperatures from 5-17oC, anything above which they die. They also need a high supply of oxygen in water,” Ta said, adding that it was a hard job.

At the beginning, Ta let rain water run directly through the salmon pools, but found that leaves and other components in the rainwater killed the fish. After a while, Ta got adopted other techniques and things improved.

“Salmon are easily caught fungus in polluted water. So in the rainy season, when the water is mixed with leaves and other kind of waste, I have to stay by the pools the whole day and night to filter the water from the stream, or else the fish would all die,” he said.

Tạ also had to use lots of salt to help the fish stay clean. “Sometimes I have to buy a tonne of salt a month. Summer is the most difficult time because fish often get bacterial contamination from stream water,” he smiled.

Starting with 800, Ta now has 2,000 salmon each year.

Previously, Ta could only harvest salmon once a year, but currently thanks to modern technology, he can do so twice a year. A mature fish weighing between 1.5kg and 2kg brings in up to 500,000 VND (22 USD) per kilogram.

Ta has been co-operating with another resident in his commune, Trieu Van Trinh, to expand the farm model. Trinh now has 10 salmon pools with over 3,000 fish.

Ninh Van Xa, deputy head of the Mau Son Tourism Management Board, said Ta’s salmon farming model was the first of its kind in the area and opens up many opportunities for local residents.

Salmon and sturgeon were first raised in Sa Pa district, Lao Cai province, in 2005. 

After 10 years, cold-water fish farming has thrived in Sa Pa, with a total output of 265 tonnes in 2015.

The Research Institute for Aquaculture No 1 is the country’s first cold-water hatchery and is currently home to nearly 30,000 salmon, including 17,000 mature fish raised from eggs. Each year the centre provides 50-60 thousand salmon roe to the local market.
