Skin mucus is the first barrier of fish defence. Proteins from skin mucus of European sea bass ( Dicentrarchus labrax ) were identified by 2DE followed by LC‐MS/MS. From all the identified proteins in the proteome map, we focus on the proteins associated with several immune pathways in fish. Furthermore, the real‐time PCR transcript levels in skin are shown. Proteins found include apolipoprotein A1, calmodulin, complement C3, fucose‐binding lectin, lysozyme and several caspases. To our knowledge, this is the first skin mucus proteome study and further transcriptional profiling of the identified proteins done on this bony fish species. This not only contributes knowledge on the routes involved in mucosal innate immunity, but also establishes a non‐invasive technique based on locating immune markers with a potential use for prevention and/or diagnosis of fish diseases.
