Aquaculture has been experiencing a boom since the mid-1970s, sustaining an average annual growth rate of around 9% until a recent slight fall back.
Today it continues to expand in almost all regions of the world and is the fastest growing food animal production sector globally.
There is substantial and growing international trade in live aquatic animals and their products.
A detailed analysis of aquaculture production and wild capture fisheries is published every 2 years by FAO.
However, infectious diseases are causing major aquaculture production losses in many countries, even having a significant negative impact on some national economies
In some countries, the rapid increase in aquaculture output has been based on species diversification which has led to an increase in the demand for introduction and transfers of live non-indigenous aquatic animals, some of which have introduced new diseases with them.
Economic losses of many $100 millions.
High numbers of farms closed and large numbers of job losses.
Will take years to recover.
A national disaster.

The OIE standards applicable to international trade in aquatic animals and their products are laid out in the OIE Aquatic Animal Health Code and in the OIE Manual of Diagnostic Tests for Aquatic Animals.
The OIE standards and guidance in the Aquatic Code and Aquatic Manual aim to reduce disease risks
Guidelines for risk analysis
Zoning & compartmentalisation
Quality of Aquatic Animal health Services
Criteria for disease freedom
Conditions for trade
Model export certificates
Surveillance for disease
Disease reporting obligations
Transport of farmed fish
OIE listed diseases
Procedures for aquatic animal waste disposal
Responsible and prudent use of antimicrobial agents
Stunning and killing of farmed fish for human consumption
General Provisions (Horizontal issues)
General Provisions (contd)
Disease specific chapters
(OIE listed diseases - of importance to international trade)
A disease proposed for listing should meet all the relevant parameters set for each of the criteria;
Parameters that support a listing include:
Such proposals should be accompanied by a case definition for the disease.
An emerging disease means a newly recognised infection resulting from the evolution or change of an existing pathogenic agent, a known infection spreading to a new geographical area or population, or a previously unrecognised pathogenic agent or disease diagnosed for the first time and which has a significant impact on aquatic animal populations or public health.
disease detection to OIE
In this context, it is important to understand that the circumstances for regular as well as immediate notification of aquatic animal diseases do not require the presence of clinical disease or mortality.
The Aquatic Code clarifies in Article 18.104.22.168:
“This means that the presence of an infectious agent, even in the absence of clinical disease, should be reported.”
General obligations related to certification
Criteria to assess the safety of aquatic animal commodities
Control of aquatic animal health risks associated with transport of aquatic animals
Aquatic animal health measures applicable before and at departure
Aquatic animal health measures applicable during transit from the place of departure in the exporting country to the place of arrival in the importing country
Frontier posts in the importing country
Aquatic animal health measures applicable on arrival
Measures concerning international transport of aquatic animal pathogens and pathological material
Model health certificates for international trade in live aquatic animals and products of aquatic animal origin
2 sets of criteria:
Criteria to assess the safety of aquatic animal commodities irrespective of country disease status
Criteria to assess the safety of aquatic animal products destined for human consumption irrespective of country disease status
6th edition, 2009
