When does the Pangasius rearing exist in Vietnam?
October 08, 2015, 03:28 PM

Pangasius rearing has traditionally been carried out in the Southern of Vietnam since the 1950s.  Tra fish can be reared in pond or cage and Basa fish mainly in cage. 

Cage rearing was originated from Tonlesap of Cambodia and has initially been applied in Chau Doc, Tan Chau (An Giang province) and Hong Ngu (Dong Thap province) since 1950s by repatriate Vietnamese. With the advancement and completion of experience and techniques, cage rearing became complete and stable. The greatest number of cages in 2004 was 2,333 units. Up to April, 2009, the number of cages was just over 100 units.

Rearing Tra fish in pond has been started in Mekong River Delta since 1970s and until now most of Pangasius to process for export is used this way of aquaculture.

Where is the source of the breeding stock:

The source of Tra and Basa breeding stock initially depended on natural capture. Annually, at the beginning of lunar May, when rainwater from the upstream of the Mekong River drained out, fishermen in Tan Chau (An Giang) and Hong Ngu (Dong Thap) used a funnel shaped net, called “day” to catch fry. The later were transported to ponds and reared into fingerlings with a length of 7 - 10cm which were then sold to farmers in the whole Southern regions to be raised in pond or cage. Hatcheries were mostly located in Tan Chau, Chau Doc, Hong Ngu and islands of Tien River, such as Long Khanh, Phu Thuan. During the 1960s and 1970s, number of annually caught fry varied from 500 to 800 millions individuals, and of fingerlings from 70 to 120 millions.

Researches on artificial propagation of Pangasius in Vietnam were respectively undertaken in 1978 and 1990. The first successful artificial propagation had been done in May 1995 in laboratory of Can Tho University, under the framework of joint research between  the “Centre de coopération Internationale en Recherche Agronomique pour le Développement” (CIRAD) - France, University of Can Tho and Fisheries Import and Export Joint Stock Company (AGIFISH Co.). Until 1999, as Vietnam became active and socialized the artificial propagation of Tra and Basa breeding stock, the wild fry catching had been stopped. Since then, Pangasius culture in Vietnam becomes stable and has been dramatically increased. Pangasius production reached to 1.4 millions tons by the end of 2011.
