The Andhra Pradesh Shrimp Seed Production,
Supply and Research Centre (TASPARC)
The continued expansion of Penaeus vannamei farming in India is being supported by a collaborative research project under the leadership and support of the Marine Products Export Development Authority’s (MPEDA) Chairwoman Leena Nair through the Rajiv Gandhi Centre for Aquaculture (RGCA) and the Oceanic Institute (OI), part of Hawaii Pacific University in the United States.
The project focuses on production of specific-pathogen-free (SPF), selectively bred P. vannamei broodstock that exhibit good reproductive performance, as well as fast growth and high survival on commercial farms in India.
Genetically diverse cohorts of shrimp families produced at OI's Nucleus Breeding Center in Hawaii, USA, are shipped to India for performance evaluations at commercial test farms. After about 70 days of growout, the shrimp are harvested, and performance data are collected and analyzed. Once top-performing families are identified, siblings from those families, which are kept at the OI breeding center in Hawaii, are used to produce SPF offspring, which are then shipped as postlarvae to a broodstock production center in India to be grown to broodstock.
The Andhra Pradesh Shrimp Seed Production, Supply and Research Centre (TASPARC), the broodstock center for this project, is located in Visakhapatnam, Andhra Pradesh, India. Strict biosecurity and implementation of best management practices are critical components of the research collaboration. This effort is supported by the RGCA Aquatic Quarantine Facility for P. vannamei located in Chennai, Tamil Nadu, India.
Upon arrival in India, all shrimp are maintained in quarantine for five days, where they are monitored and tested for specific shrimp pathogens. Once shrimp test negative for pathogens, they are transferred to a commercial test farm for field evaluations or to TASPARC for growout.
To maintain a high level of biosecurity, TASPARC is equipped with both influent and effluent seawater treatment systems that incorporate mechanical filtration, ozone disinfection and ultraviolet disinfection, as well as recirculating culture systems to reduce water exchange. In addition, a pathogen surveillance program ensures the SPF status of all shrimp reared at the facility.
The program performs testing for the presence of whitespot syndrome virus, Taura syndrome virus, yellowhead virus, infectious hypodermal and hematopoietic necrosis virus, infectious myonecrosis virus, monodon baculovirus, bacilliform virus, hepatopancreatic parvolike virus, Mourilyan virus and necrotizing hepatopancreatitis virus. Histological analysis is also conducted periodically as a management tool to identify any abnormalities that may indicate poor animal health.
Disease testing is conducted by the RGCA diagnostic laboratory in Sirkali, Tamil Nadu, India—the only National Accreditation Board for Testing and Calibration Laboratories-accredited aquaculture pathology laboratory in India—and the Aquaculture Pathology Laboratory at the University of Arizona in the United States, an independent laboratory certified by the World Organization for Animal Health (OIE).
Soon after operations began, an independent biosecurity audit and facility evaluation conducted by the University of Arizona determined that TASPARC complied with all biosecurity requirements to prevent the entrance and spread of OIE-listed diseases of penaeid shrimp.
TASPARC broodstock are reared in a two-phase growout system. Postlarvae are grown in phase-1 modules to weights of approximately 15 to 20 grams before being transferred to separate phase-2 modules, where they are grown at lower densities to 40 to 50 grams. It takes approximately six months to raise the shrimp to broodstock size.
All shrimp-rearing facilities are located within enclosed buildings with various levels of transparent roofing that can be adjusted for the right amount of natural light and temperature. Microalgae are produced on site, and cultures are used to inoculate culture systems and maintain blooms in both phases of growout. High-quality shrimp feed imported from the USA ensures optimal nutrition during growout.
Water quality is closely monitored, and any seasonal environmental fluctuations are kept at a minimum. The facility also includes a broodstock distribution area, where broodstock shrimp are acclimated and packaged for transport to hatcheries in India.
TASPARC began operations in early October 2012, when it received the first batch of SPF P. vannamei postlarvae from OI. Over the first 18 months of operation, TASPARC produced and distributed over 47,800 SPF P. vannamei broodstock to local hatcheries. To date, over 60 hatcheries in India have received broodstock from TASPARC, and derivative postlarvae have been supplied to farmers in various regions throughout India. The current project has the capacity to produce over 45,000 broodstock annually.
