Disease Problems, But Production Continues to Increase


At the Global Aquaculture Alliance’s GOAL 2017 Conference (Dublin, Ireland, October 3–6, 2017), Maple Hung, vice president of global markets for Sheng Long Bio-Tech International Co, said whitespot virus, early mortality syndrome (EMS), Enterocytozoon hepatopenaei (EHS) and white feces disease continue to be problems for Vietnamese shrimp farmers.  However, she said the shrimp farming industry is still expanding.


Disease challenges aside, shrimp farmers are getting improving pond results with “semi-biofloc and zero-water exchange with probiotic culture,” said Hung.  Production of Penaeus vannamei is still expanding, while some farmers shift back to P. monodon in response to higher prices.  White feces disease, which was first recorded in Thailand in 2010, is also increasing.


Loc Tran, director of ShrimpVet, a distributer of shrimp seedstock and a provider of consulting and laboratory services to the shrimp farming industry, added that unpredictable weather as well a lack of finances and technology were also persistent obstacles.  He said heavy rains and flooding have seemingly made the whitespot virus more widespread in the Mekong Delta.  Outbreaks EHP are on the rise in hatcheries and shrimp ponds.  He said the disease, which wrecks havoc on the digestive systems of shrimp, “is strongly associated with pollution and excess algae, which lead to blooms of bacteria on pond bottoms.”


Inland, low-salinity shrimp farming is being adopted in some areas.
