1. HYBRIDISATION IN SHRIMP BREEDING

2. INTRODUCTION genetically stronger shrimp
The main objectives of Hybridization is to improve the organisms in terms of their physical, biological and reproductive features including genetic status by combining the haploid genome of two different parents species of either same or different genera or of same species
Hybridization in shrimps may lead to –
genetically stronger shrimp
better looking shrimp - aesthetics
Disease resistance
Faster growth rate

3. EXPERIMENTS DONE SOFAR IN SHRIMP HYBRIDIZATION
HHA’s SPF TVR Vannamei accounts for more than 50% of broodstock imports to Thailand.
HHA has selected for resistance to Taura Syndrome and fast growth through 8 generations and has now hybrid crossed
the new GxTVR line shares the same growth characteristics of the fastest growing SPF lines and resistance to Taura Virus.
HHA’s P. monodon stock is now in its 8th generation of domestication.
Recently hybrid crossed between Australian and Red Sea origins, continued improvement in growth rates are being achieved.
Available for commercial scale production later this year.

4. EXPERIMENTS DONE SOFAR IN SHRIMP HYBRIDIZATION
HHA recently produced Founding Stock for New Caledonia’s Shrimp Association.
Over a multi-year program, HHA successfuly produced 12 distinct families
Maintains these lines at their facilities as back-up genetics.

5. OUTCOMES OF HYBRIDIZATION IN SHRIMPS
• Development of SPF P. monodon
• Development of Taura Virus Resistance(TVR)
• Development of White Spot Resistance(SPR)
• Development of Improved Performance
Better looking shrimp with greater control over aesthetics.
