Abstract

In the last years German food control laboratories have established proof of a significant number of cases of incorrectly labelled flatfish on the German market. A flatfish offered as sole (Solea vulgaris) in Southern Germany served as an example for mislabelled flatfish and for the difficulties food control laboratories may encounter and to identify products of unknown origin. Morphometric and meristic examination, as well as isoelectric focusing of sarcoplasmic proteins, PCR-based DNA-analysis failed to identify the fish. By using these methods, it only could be excluded that the fish belonged to the species of Solea vulgaris or another described flatfish species. DNA sequencing of an amplicon gave a sequence identical to a sequence in GenBank, which, however, turned out to be incorrectly assigned to Solea vulgaris. More research about characterization and identification of tropical flatfish is recommended, because of the growing importance of these fishes for the European market.
