Milestone for pangasius farming in Vietnam
Janne Brodin (English translation: Ane Skjelfjord)PhD student Sàng van Nguyen has led a project which has initiated breeding efforts on pangasius as a farmed fish in Vietnam. Pangasius is one of the most expansive species of farmed fish in the world today, and has at times “flooded” the European market as a reasonably priced white fillet fish product.

The English name for pangasius is striped catfish.
Efficient breeding
This doctoral work has followed the species through two generations. The emphasis of the selection has been on improved weight gain. The work has also shown that it is possible to measure quality traits like fat and fillet yield on live fish, making the breeding efforts that much more efficient.
The thesis has also estimated genetic parameters for other traits that are important to the breeding program.
No more fry caught in the wild or broodstock
In addition to the need for improving pangasius as a farmed fish species, its farming has until recently been based on fry caught in the wild or on broodstock, a fact which has become threatening to the wild population.
The breeding effort – a mainstay
This is first of all a milestone for pangasius farming in Vietnam. The recently started breeding program will be the most important factor in the development of this farmed fish species, as we have seen it for salmon in Norway. A genetic improvement of 10 % per generation on traits like weight gain is essential for a financially viable production.
Sàng van Nguyen is 37 years old and comes from Vietnam. He took his Master of Aquaculture from IHA in 2004.
Title of the thesis: Genetic studies on improvement of striped catfish (Pangasianodon hypophthalmus) for economically important traits.
His lecture will be on: Optimization of simple (low input) and advanced (high input) breeding plans in fish.
Sàng van Nguyen will defend his thesis on Friday 26th November 2010 at 12:15, in Auditorium H109 at the Department of Animal and Aquacultural Sciences, UMB.
