Clarification: Shrimp disease SHIV detected in China, Thailand, but not Vietnam
(Editor`s Note: This story has been clarified to reflect that shrimp hemocyte iridescent virus has been confirmed in China and Thailand. While concern exists that the disease is present elsewhere in Southeast Asia, it has not been confirmed in Vietnam as was earlier reported.)
Shrimp hemocyte iridescent virus (SHIV), a sometimes fatal disease which has been detected in China, is suspected elsewhere in Southeast Asia.
In an Oct. 1 phone interview with Undercurrent News, George Chamberlain, president of the Global Aquaculture Alliance, said that SHIV has been detected in southern China and Thailand at "a very low prevalence".
"We have not yet detected it in Vietnam,â€ť he said.
An earlier story from Undercurrent stated that SHIV had been found in Vietnam and while there is concern that the disease could spread to other countries in Southeast Asia, it has not been detected in Vietnam.
â€śAs with any new disease we have to keep an eye on it and track it,â€ť Chamberlain said.
Loc Tran, founder of the ShrimpVet Laboratory, speaking during the 2018 Global Outlook for Aquaculture Leadership (GOAL) conference in Guayaquil, Ecuador, alluded to SHIV`s presence in Southeast Asia.
"We still have major problems, mostly from disease. You may notice we have EMS, white spot, EHP and white feces. And quite recently we suspect that a new viral disease, SHIV, might have arrived to Vietnam and other Asian countries," he said.
Chamberlain reiterated during the phone interview that SHIV has been confirmed to date only at low levels in China and Thailand.
"At this point we don`t see much, but weâ€™re concerned and we think it`s important to have surveillance effort in place like Loc has done," the GAA president said, adding: â€śI think it would be wise for diagnostic labs around the world to begin surveillance for SHIV so we get a handle on exactly where it isâ€ť.
Speaking more generally on shrimp disease issues during GOAL, Tran said biosecurity, functional feeds, and replacing live feed for broodstock to prevent shrimp disease "are vital", pointing at a decline in survival rates in India.
