Penaeus vannamei is an exotic shrimp species that has gained high culture momentum, since its introduction to India . Currently, the culture of the species in the Country is being done by the shrimp farmers by importation of Specific Pathogen Free (SPF) vannamei broodstock from approved suppliers, which are located overseas. The value of one brooder normally ranges from 50 to 61 US $, excluding the custom duty, processing fee and other charges for the transboundary shipment of the stock to India. The P. vannamei stock are permitted to be imported to the Country by the hatchery operators only through the single declared port of entry, i.e. Chennai in Tamil Nadu in the Country. The imported parent shrimps are then to be quarantined at the Aquatic Quarantine Facility before being transported to the vannamei hatcheries . This article reports the data available on import of vannamei broodstock to India since its importation to India in 2009. The dataset presented here contains information on transit and quarantine mortality of the brooders following the shipment of the stock by the various broodstock suppliers from the overseas.
Value of the data
The data presented in this article shows the supplier wise import, quarantine and transit mortality of the P. vannamei stock since the introduction of vannamei culture in the Country (Table 1). A comparison of the mortality rates (percentage mean) during shipment and quarantine is provided in Table 2.
The importation data of P. vannamei brooders to India from different approved broodstock suppliers was collected from the quarantine facility, since its inception. The data on transit and quarantine mortality was obtained and subjected to statistical analysis using Graphpad prism 7.0 software. The normal duration of broodstock shipment from the suppliers is provided. However, the unusual delays in shipment caused due to flight delays and change in flight routes are not considered while indicating the overall shipment duration in the data given. The mean and the standard error of the data when normally distributed is presented. Tukeys Multiple comparison test at 0.05 level was used to compare the data obtained on quarantine and shipment mortalities between the different suppliers (Fig. 1, Fig. 2).
