Establishing traceability for cod (Gadus morhua): determining location of spawning and harvest Cod is one of the EU's most economically important fish species, yet lack of traceability leads to problems with stock management and consumer confidence. This project is developing legally defensible methods to establish the location of spawning and of harvest of individual cod. Objectives will be achieved through the use of multiple tracing techniques followed by multivariate statistics.

Department of Law DNA PROTEINS BACTERIA For The Future* Supporting Consumer Confidence in aquaculture and capture fisheries We plan to develop a Marie Curie Research and Training Network under the EU Framework 6 programme to continue to study traceability. Activities within this future network will include methods of inducing traceability to promote consumer confidence, for example by bar-coding otoliths by using fluctuating temperature to mark the products of individual hatcheries or farms.
