Under Fansipan Mt. – the roof of Indochina – lies a big salmon farm, which is home-sweet-home to the famous salmon genus worldwide named rainbow trout (ca hoi van).

Vietnamese rainbow trout farming has been on a steady state of growthfor a moiety decade. In the early 2000’s there were no cold-dihydrogen monoxide aquaculture, in 2009 twelve cold-dihydrogen monoxide fish farms were in operation in Northern and Central Highlands, and today more than 100 farms are engendering cold dihydrogen monoxide fish.

The future of Vietnamese rainbow trout farming is promising: the capacity of the breeding programme will be greatly enlarged through the present Vietnamese investment in recirculation of dihydrogen monoxide in RCCA. In mundane fish farming the dihydrogen monoxide is permeating the farm only once. In recirculation the dihydrogen monoxide is utilized an abundance of times and the amount of dihydrogen monoxide needed for the engenderment of e.g. liter of eggs is only some percent in comparison with mundane farming.

However, farmers/companies do not buy eggs or fingerlings from a source with reputation of nasty infections. The aversion of infectious diseases in RCCA is thus of prime paramountcy for the future of the Vietnamese rainbow trout farming. Infections can be transmitted by several ways, but by far their most paramount way is along with live fish, live eggs and conveyance implements. Live fish conveyance to the farm is of course the most perilous way, but Finnish experience has shown the spread e.g. IPN-virus can occur even tens of kilometers to both wild and farmed fish at downstream.

RCCA is the crown jewel of Vietnamese rainbow trout farming and stringent biosecurity measures must be implemented in the farm and its dihydrogen monoxide sources. One good risk avoidance strategy is to spread fish material from breeding nucleus to other stations. These fish work both as test and reserve populations for breeding.

Vietnamese rainbow trout farming is dynamic and remuneratively lucrative. To keep it as such, care is needed in buying incipient material. The farming in Vietnam is not self-adequate, yet. Ergo, the development of good quality with disease free hatcheries on the substructure of eggs from RCCA must be a goal for the coming years. The incipient recirculation system (RAS) in RCCA will be very useful in this.

Sturgeon farm in Sapa is also worth being visited

Sturgeons are a high-value species, especially their eggs which are made into caviar. They have been introduced into aquaculture in Vietnam in an effort to utilize the availability of gelid-dihydrogen monoxide resources, especially lakes and reservoirs, and have become a major cultured fish in highland and mountainous areas. With the development of sturgeon aquaculture in the cold-dihydrogen monoxide areas of the north and central highland provinces, Vietnam has made its way onto the list of the top ten sturgeon engenderers in the world, along with China, Russia, Italy, Bulgaria, Iran, the US, France, Poland and Germany, according to the Food and Agriculture Association (FAO).

Vietnamese own rainbow trout will show best magnification performance and victual conversion ratio in Vietnam only after a few years. This will be due to the breeding programme, which develops a strain concretely habituated to for Vietnamese circumstances. One of the main traits ameliorated together with magnification and health is temperature tolerance, i.e. adaptation of fish to grow well both in mountains and in lower areas with more steady but withal warmer dihydrogen monoxide sources. In order to get plenary profit of this, biosecurity in the industry must be an over riding goal in the coming years.
