In this book, for the first time, scientists from various disciplines and all partners in the fishery chain address the important issues of quality labelling, monitoring and traceability of fish. The complexity of the European fishery sector, the attitudes towards quality labelling GMP and the needs for quality information are presented. The progress of implementing traceability (schemes) from catch to consumer is covered. Fishermen give their view on GMP on board of their vessels. New tools for measuring the quality of the catch and the experience with quality grading of the landed fish by QIM are described. Attention is paid to recent developments of E-commerce of fish via the auctions. The possibilities of combining various instrumental methods for measuring fish quality are highlighted. A range of contributions on labelling systems, industrial standards, awards and certification procedures for the quality of fish are included. An overview on consumer research on fish in Europe is presented.
