Virus decimates shrimp population
Virus decimates shrimp population
Up to 900 million breeding shrimp have died in the southern province of Tra Vinh, causing farmers initial losses of VND1 trillion (US$48 million).
The dead shrimp accounted for 50 per cent of the total in the province, according to the provincial Agricultural and Rural Development Department.
The shrimp, which were from 15-45 days old, died of the infectious hypodermal and haematopoietic necrosis virus (IHHNV), reported the department.
Uncertainty over where the shrimp originated from could also be a factor, said Pham Minh Truyen, deputy director of the department.
Only 37 per cent of the shrimp had been through local quarantine stations located in the districts of Chau Thanh and Duyen Hai since the start of this year, Truyen said.
Around 1.8 billion breeding shrimp are raised across 23,000ha in the districts of Cau Ngang, Chau Thanh, Duyen Hai and Tra Cu
