The source of stock has become a significant issue for international aquaculture. Stock of many aquaculture species has been translocated between countries and even continents, with some of these moves resulting in the transfer of diseases with that stock. The benefits of translocating stock need to be balanced against the risks involved. Importing stock should only be undertaken with appropriate safeguards, such as adequate health checking and quarantine procedures, in place to minimize the risk of introducing disease, as recommended in Article 9 of the Aquaculture Development section of the FAO Code of Conduct for Responsible Fisheries (the Code).
