Employees of shrimp broodstock are produced in
Vietnam have been imported from Hawaii that have free
5 pathogens (MBV, IHHNV, TSV, WSSV, YHV).
•
When using domescated shrimp, it essenal to obtain
adequate background informaon on the origin of the
stocks and their past performance.

•
Preferably, the maturation room should have
round tanks that are dark-coloured, smooth-
sided, and of approximately 5 m diameter.
•
The broodstock should be held with flow-
through (new and/or recycled) water exchange
of a total of 250-300% per day and a
continuous, but not too vigorous air supply,
•
Water depth is generally around 0.5-0.7 m,
Maturation tanks shape
•
The shrimp are stocked at a rate of around 6-8 shrimp per sq. m. bottom
surface area with a male to female ration of 1-1.5:1. Thus, a 5 m diameter tank
can accommodate 60-80 females and 60-100 males.
•
Water temperatures are usually controlled to be maintained in the range of
28-29
o
C, with a salinity of 30-35 ppt and pH of 8.0-8.2.
•
The feed preparation area should be adjacent to, but separated from, the
maturation room
