Taura syndrome is a disease mainly of the nursery phase of Penaeus (Litopenaeus) vannamei. It usually occurs within 14 to 40 days of stocking postlarvae into grow-out ponds or tanks and results in mortality rates of 40% to more than 90%. • TSV has been documented in postlarvae, juvenile and adult life stages.
What is WSSV in shrimp?
White spot syndrome virus (WSSV) has a worldwide distribution and is considered one of the most pathogenic and devastating viruses to the shrimp industry.

- Do not dispose of prawn waste (heads and shells) in or near waterways.
How is Taura syndrome prevented?
Methods of control. Management strategies for the disease have included raising more resistant species such as the Western blue shrimp (Penaeus stylirostris) and stocking of specific pathogen free (SPF) or specific pathogen resistant (SPR) shrimp.
Is white spot disease contagious to humans?
While this is a highly contagious viral disease of prawns, it does not pose a threat to human health or food safety.
