for Asiatic region. The participating countries should maintain clear records, which will helpin tracing the source material for taking corrective measures in containing the occurrence ofdiseases. In this regard, disease-reporting system developed for Asiatic region by NACA hasto be taken seriously and implemented.Import risk analysis: Prior to introduction of any exotic species, it is essential to conductimport risk analysis that is based on the best available scientific information. Risk assessmentmust include both qualitative.and quantitative risk assessment, associated with a variety ofaquatic animals and likely hazards associated with a specific import. The quarantine policyhas to address a number of factors including safe-guarding humans, animals, plants and theenvironment. Import of aquatic animals involves a high degree of risk either to the nativeaquatic fauna or even to humans, due to possible introduction of new pathogens, which arenot present in the importing country. Hence it is essential that the importing country conductsimport risk analysis prior to importation of aquatic animals in to the country.Epidemiological information: Countries have to make available to other countries, throughthe OIE, the information that is necessary to reduce spreading of important aquatic animaldiseases and their aetiological agents and to assist in achieving better world-wide control ofthese diseases. In addition, information on the measures taken to prevent the spread ofdiseases, including possible quarantine measures and restrictions on the movement of aquaticanimals, aquatic animal products, biological products and other miscellaneous objects thatmay be responsible for transmission of disease must be also made available to an importingcountry.Diseases notifiable to the World organisation for animal lzealtlz (OIE): It is the list ofcommunicable diseases that are considered to be of socio-economic or public healthimportance within countries and that are significant in the international trade in aquaticanimals and aquatic animal products. Reports of these diseases are normally submitted once ayear. Taura Syndrome, white spot disease and yellow head disease are notifiable shrimpdiseases listed by the OIE.Aquatic Animal Quranfine Policy in India: India is yet to have a aquatic animal quarantinepolicy. However, an effort towards establishment of a quarantine policy has been initiated bythe Indian Council of Agricultural Research involving National Bureau of Fish GeneticResources, Lucltnow, Central Institute of Brackishwater Aquaculture, Chennai, CentralMarine Fisheries Research Institute, Kochi, Central Institute of Freshwater Aquaculture,Bhubaneshwar and other fisheries Institutes in the country.
