Chapter 3 of Part 1 of The Aquaculture and Fisheries (Scotland) Act 2013 provides powers for the Scottish Ministers to control the movement of commercially damaging species.
Commercially damaging species are defined within the Act as being a species which is specified in an order made by the Scottish Ministers where Ministers consider that, if not controlled, the species would be likely to have a significant adverse impact on the economic or commercial interests of a fish or shellfish farmer and the species is itself of little or no commercial value.
The Aquaculture and Fisheries (Scotland) Act 2013 (Specification of Commercially Damaging Species) Order 2014 came into force on 23rd August 2014.
It specifies Mytilus trossulus, a type of mussel, as a commercially damaging species. When suspected, Mytilus trossulus, must be notified to Scottish Ministers as soon as reasonably practicable. Where the Scottish Ministers are satisfied that Mytilus trossulus is present the Order will enable the emergency control measures - control agreements, control schemes, emergency action notices and associated powers and offences- to be brought in to deal with that species of mussel.
