Regions of the Atlantic area are characterised by an intense economic and social relationship with marine resources. Most of them are linked with important fishery and aquaculture industries. For these regions, seafood traceability and labelling are essential, as their products may be under threat from low-cost, third country imports. Imports which could potentially be of doubtful origin and/or which may have been handled or produced under inadequate controls. The main objective of LabelFish was to set up a network of entities interested in developing a common traceability strategy, using standardised and innovative analytical techniques of genetic traceability and labelling of seafood products in the European Atlantic areas. Protection of European consumers and SMEs was achieved by ensuring consumers’ rights to correct product information and by implementing reliable genetic traceability and authentication tools for the protection of market niches.
