Article 25g Specific rules for aquatic containment systemsF1
United Kingdom
Closed recirculation aquaculture animal production facilities are prohibited, with the exception of hatcheries and nurseries or for the production of species used for organic feed organisms.
Rearing units on land shall meet the following conditions:
for flow-through systems it shall be possible to monitor and control the flow rate and water quality of both in-flowing and out-flowing water;
at least five percent of the perimeter ( ‘ land-water interface ’ ) area shall have natural vegetation.
Containment systems at sea shall:
be located where water flow, depth and water-body exchange rates are adequate to minimize the impact on the seabed and the surrounding water body;
shall have suitable cage design, construction and maintenance with regard to their exposure to the operating environment.
Artificial heating or cooling of water shall only be permitted in hatcheries and nurseries. Natural borehole water may be used to heat or cool water at all stages of production.
