Domestication of freshwater prawn has been established
since the 1970s by government hatcheries.
However, the number of foundation populations and
information on mating scheme were not known. A
number of private hatcheries in Thailand have been
using broodstock identified as local strains to produce
larvae. Despite a long aquaculture history, the genetic
structure of these local stocks has not been determined.
In addition, several private hatcheries have introduced
non-native prawn broodstocks from India and Myanmar
(Nithid Patarakulchai, pers. comm.) to replace or
upgrade their own stocks due to the inconsistency of
prawn production of the local populations.
