Study on pathogens in cold water fish

Lam Dong Department of Science and Technology said that in recent years salmon and sturgeon (collectively known as cold water fish) have become important local farming objects.

However, the current problem is when developing aquaculture on a large scale, often accompanied by epidemics, causing significant losses to the farming industry.

According to a recent study by the Research Institute for Aquaculture No. 3, at least six species of parasites have been found in salmon, with prevalence ranging from 0.3 to 38%; At the same time, three species of parasites were found in pond sturgeon and five parasite species in cage culture sturgeon.

Scientists have not found the parasite harmful to humans in these coldwater fish species in Lam Dong.

In addition, the research team also discovered three groups of diseases including hemorrhage, sores; gynecological diseases and fin rot, tail-wear; are bacteria caused by cold water fish in Lam Dong.

The Aquaculture Research Institute 3 encourages farmers to take measures such as bathing with old oxygen water, or salt water to treat diseases caused by parasites and fungi on sturgeon and salmon; cleaning ponds every farming season; raise fish with appropriate density.

Cold water fish farming in Lam Dong in particular and the country in general is totally dependent on importing breeds and eggs from abroad, this may be a pathway to bring strange pathogens into Vietnam.

Lam Dong currently has 35 units, organizations and individuals that have been granted investment agreements by the province or granted certificates of investment in coldwater fish development, with a total registered area of ​​3,072ha, including cold water fish farming areas is 376ha.
