For the purpose of the Aquatic Code:

Aquaculture

means the farming of aquatic animals with some sort of intervention in the rearing process to enhance production, such as regular stocking, feeding, protection from predators, etc.

Aquaculture establishment

means an establishment in which fish, molluscs or crustaceans for breeding, stocking or marketing are raised or kept.

Aquatic animal health status

means the status of a country, zone or compartment with respect to an aquatic animal disease, according to the criteria listed in the relevant chapter of the Aquatic Code dealing with the disease.

Aquatic animal products

means non-viable aquatic animals and products from aquatic animals.

Aquatic animals

means all life stages (including eggs and gametes) of fish, molluscs, crustaceans and amphibians originating from aquaculture establishments or removed from the wild, for farming purposes, for release into the environment, for human consumption or for ornamental purposes.

Aquatic Code

means the OIE Aquatic Animal Health Code.

Aquatic Manual

means the OIE Manual of Diagnostic Tests for Aquatic Animals.

Basic biosecurity conditions

means a set of conditions applying to a particular disease, and a particular zone or country, required to ensure adequate disease security, such as:

  1. the disease, including suspicion of the disease, is compulsorily notifiable to the Competent Authority; and

  2. an early detection system is in place within the zone or country; and

  3. import requirements to prevent the introduction of disease into the country or zone, as outlined in the Aquatic Code, are in place.

Bias

Biosecurity plan

means a plan that identifies significant potential pathways for the introduction and spread of disease in a zone or compartment, and describes the measures which are being, or will be, applied to mitigate the risks to introduce and spread disease, taking into consideration the recommendations in the Aquatic Code. The plan should also describe how these measures are audited, with respect to both their implementation and their targeting, to ensure that the risks are regularly re-assessed and the measures adjusted accordingly.

Buffer zone

means a zone established to protect the health status of aquatic animals in a free country or free zone, from those in a country or zone of a different aquatic animal health status, using measures based on the epidemiology of the disease under consideration to prevent spread of the disease agent into a free country or free zone.

Early detection system

means an efficient system for ensuring the rapid recognition of signs that are suspicious of a listed disease, or an emerging disease situation, or unexplained mortality, in aquatic animals in an aquaculture establishment or in the wild, and the rapid communication of the event to the Competent Authority, with the aim of activating diagnostic investigation with minimal delay. Such a system will include the following characteristics:

  1. broad awareness, e.g. among the personnel employed at aquaculture establishments or involved in processing, of the characteristic signs of the listed diseases and emerging diseases;

  2. veterinarians or aquatic animal health specialists trained in recognising and reporting suspicious disease occurrence;

  3. ability of the Competent Authority to undertake rapid and effective disease investigation;

  4. access by the Competent Authority to laboratories with the facilities for diagnosing and differentiating listed diseases and emerging diseases.

Emerging disease

means a newly recognised serious disease, the cause of which may or may not yet be established, that has the potential to be spread within and between populations, for example by way of trade in aquatic animals and/or aquatic animal products.

Epidemiological unit

means a group of animals that share approximately the same risk of exposure to a disease agent with a defined location. This may be because they share a common aquatic environment (e.g. fish in a pond, caged fish in a lake), or because management practices make it likely that a disease agent in one group of animals would quickly spread to other animals (e.g. all the ponds on a farm, all the ponds in a village system).

Eviscerated fish

Fallowing

means, for disease management purposes, an operation where an aquaculture establishment is emptied of aquatic animals susceptible to a disease of concern or known to be capable of transferring the disease agent, and, where feasible, of the carrying water. For aquatic animals of unknown susceptibility and those agreed not to be capable of acting as carriers of a disease of concern, decisions on fallowing should be based on a risk assessment.

Feed

means any material (single or multiple), whether processed, semi-processed or raw that is intended to be fed directly to aquatic animals.

Feed additives

means any ingredient intentionally added in micro-amounts not normally consumed as feed by itself, whether or not it has nutritional value, which affects the characteristics of feed or animal products. Micro-organisms, enzymes, acidity regulators, trace elements, vitamins, substances used to attract aquatic animals to feed and promote feed intake, pigments, synthetic binders, synthetic amino acids, antioxidants and other products fall within the scope of this definition, depending on the purpose of use and method of administration. This excludes veterinary drugs.

Feed ingredient

means a component, part or constituent of any combination or mixture making up a feed, including feed additives, whether or not it has a nutritional value in the animal’s diet. Ingredients may be of terrestrial or aquatic, plant or animal origin and may be organic or inorganic substances.
