Description The Indian tiger shrimp Penaeus monodon is the
principal species being cultured. Of late hatchery sector
is being dependent on wild gravid females due to non
response of broodstock to eyestalk ablation. High cost of
gravid females compelling the grow-out sector to stock
pathogen carrier seeds. Hence domestication of tiger
shrimp is essential to produce Specific Pathogen Free
(SPF) broodstock / Disease Resistant (DR) broodstock.
Merits and demerits of SPF versus DR broodstock are
presented. Development of SPF broodstock involves
stringent management of environment to arrest the entry
of pathogens and more than one economic trait can be
selected. Whereas in development of DR broodstockanimals are challenged with the pathogen and a selection
of other economic traits are less possible. Resistance in
shrimp exists at the species level as well as individual
level. Experiment on domestication of P. monodon in
which programme was advanced up to F3 generation has
revealed the existence of resistance for WSSV at the
individual level. Selective breeding programme for
development of D R broodstock involves development
of disease free base population, forming them into
families, production of F1
generation family wise through
inbreeding, challenging each family with WSSV at 3-5 g
size and rearing survived individuals up to 100 g size,
production of F2
generation by random inter crossing
between families, advancing the programme up to F5
generation. Development of DR broodstock is imperative
to ensure sustainable shrimp production
