10 Aquaculture trends

11 Aquaculture trends Intensification of aquaculture production driven by the availability of sites and ability to exploit nonagricultural land Diversification of species use, e.g. high value marine species Increasing attention on better management of the sector Increasing influence of markets, trades and consumers greater attention to food quality and safety, moving towards value adding and processing of products for export Enhancing regulation and improving governance, with emphasis on self-regulation by farmer association

12 Food safety and ecosystem integrity issues Inappropriate management frequently leads to residues and contaminants in aquatic products and environments, raising food safety and ecosystem integrity concerns.

13 Fish welfare is a growing concern

14

15 Aquaculture Started as freshwater food production systems spread to all continents all aquatic ecosystems a range of aquatic sp Different profiles of production Small scale, non commercial and family based large scale commercial and industrial production Trade at national, regional and global levels

16 Aquaculture profiling Few species Optimized feed Full scientific basis Established technology History of disease investigation Closed cycles Prevention: vaccination Corporate and wellorganized Many species Trash fish Some scientific basis Traditional technology Disease investigations are new Wild broodstock and fingerlings Treatment: antibiotics Small-holders, semi-organized

21 Possible causes for disease introduction into a country Import health requirements inadequate or non-existent or ineffectively enforced (or ignored) Unreliable disease surveillance/diagnostics in exporting country Route of entry not previously recognised or sufficiently controlled - species not previously known to be susceptible or carrier (not OIE-listed) - unrelated vector species type (amphibia and fish for ranaviruses) - ornamental/pet trade (mostly unregulated) - live animals for direct human consumption (eels, carps, molluscs) - dead animals used as bait or feed for aquatic animals (shrimps, pilchards) - processing of products in unregulated plants (shrimp, trout) - live fish transport vehicles (wellboats) - ships ballast water?

22 Live food or fresh food pathway Larval cestode Callotetrarhynchus nipponica is an example of a parasite problem of yellowtail, Seriola quinqueridiata, associated with feeding with raw anchovy, Engraulis japonica (Ogawa, 1996)

23 Live food or fresh food pathway B. Jones, Australia 100 pichards Pilchard mortality in Australia caused by herpes virus Baitfish of the species Sardinops sagax and a mix of bycatch species imported from California, Peru, Chile and Japan, without quarantine and on a scale of more than tonnes per annum for feeding sea-caged blue fin tuna in Southern Australia is near where epizootics began. It was hypothesized that this is the most likely source of the introduction of herpesvirus in Australian waters (Campbell and Hewitt, 2008)

24 Yearly shipping movements

25 Over the past two years, about 50 million tons have been added to a global fleet capacity of close to 420 million tons. In 2009 and 2010, more than 175 million tons is due to come into service. The Wall Street Journal, November

35 Responsible use of antibiotics

36 Disease outbreaks due to international trade Although local pathogens combined with other factors such as poor husbandry and inadequate water quality are the most common causes of disease outbreaks in aquaculture, the introduction of exotic pathogens through international trade in live aquatic animals and their products continues to be a major reason for new epizootics.

37 The main aim of OIE is to ensure the sanitary safety of international trade in live animals and their products. This is achieved by providing guidelines on the health measures to be used by the competent authorities of importing and exporting countries to prevent the transfer of agents pathogenic for aquatic animals, while avoiding unjustified trade barriers.

38 Developing the OIE standards for aquatic animals is the role of the Aquatic Animal Health Standards Commission

39 Aquatic Animal Health Standards Commission Members (elected in May 2009) President: Dr Barry Hill Vice President: Dr Ricardo Enriquez Sais Secretary General: Dr Franck Berthe Members: Dr Olga Haenen Dr Huang Jie Dr Victor Manuel Vidal CVO meeting - 8 December 2009, Brussels

40 OIE Standards The OIE standards applicable to international trade in aquatic animals are laid out in the International Aquatic Animal Health Code and Manual

41 Treaties and agreements related to international trade in aquatic organisms and their products Binding Agreement on the Application of Sanitary and Phytosanitary Measures (SPS Agreement) Aquatic Animal Health Code (OIE) Convention on Biological Diversity and the Cartagena Protocol on Biosafety (UNEP) Convention on International Trade in Endangered Species (CITES) European Union (EU) related legislation and directives Non-binding ICES Code of Practice on the Introduction and Transfers of Marine Organisms EIFAC Codes of Practice and Procedures for Introductions and Transfers of Marine and Freshwater Organisms Asia Regional Technical Guidelines on Health Management for the Responsible Movement of Live Aquatic Animals in Asia (TGBCIS) FAO Code of Conduct for the Responsible Fisheries (CCRF)

42 Take home messages Aquaculture is the fastest growing sector of food production Aquaculture development continuously brings new challenges regarding aquatic diseases This happens in the context of an increased societal scrutiny OIE standards are continuously improved and added

43 ... The current situation offers a big challenge and an opportunity to all concerned but, if maintained at the present level, major epidemics will continue to threaten, break out and impact the ultimate goal of aquaculture sustainability.
