| Introduction : Quality attributes of fish flesh, including food safety, organoleptic features, nutritional quality and aptitude to industrial transformation, influence consumption and acceptability of fish as food. Fish sensorial changes and texture properties are closely linked to freshness. Along with ante mortem muscle biochemistry, postmortem biochemical processes are directly linked to final quality attributes. The understanding of postmortem mechanisms is a prerequisite for an accurate control of the quality of commercialized fish by the identification of objective markers or indicators. Postmortem tenderization is one of the most important quality attributes of fish muscle. Loss of freshness is due to a complex combination of biochemical, chemical... |

| Mislabelling of food products has recently received a great deal of public scrutiny, but it remains unclear exactly what methods are being utilised in laboratories testing the authenticity of foods. In order to gain insight into the specific area of the analysis of seafood, a questionnaire focusing on the taxonomic groups typically analysed and the techniques utilised was sent to over one hundred accredited laboratories across the UK, Ireland, Spain, Portugal, France and Germany. Forty-five responded positively, demonstrating significant differences in both the species analysed and methods utilised among the countries included in the survey. Indeed, a diversity of methods was employed across laboratories and efforts to harmonise and/or standardise testing... |

| Tuna fisheries and processing represent economic activities of paramount importance around the world. Most of these products are traded for human consumption and in general are highly demanded commodities. However, not all tuna products achieve the same market price, some consumers are willing to pay a huge amount of money for certain species (i.e. Japanese market for Bluefin tuna) while other species are rather affordable (i.e. Skipjack tuna), therefore mislabelling has been observed frequently. We collected and analysed 545 tuna samples in six European countries, including fresh, frozen and canned products, and we have investigated whether or not these products were correctly labelled under European and national legislations. We found an overall... |

| Overlapping external morphometric characters easily confound the flatfishes Solea aegyptiaca and Solea solea (Soleidae) in areas of the Mediterranean Sea where both species live in sympatry. This leads to uncertainties in the fisheries and marketing of the species, in addition to misinterpretations in biogeography and conservation studies. Here we describe a simple restriction fragment length-based diagnostic test, which differentiates S. solea from S. aegyptiaca, as well as from other species of the Soleidae family. Furthermore, we show that the two species living in sympatry in the Gulf of Kavala (North Aegean Sea, Greece) present significant qualitative differences in muscle fatty acid composition, a property which can also be used to distinguish the... |

| Over the span of a decade, genetic identification methods have progressively exposed the inadequacies of the seafood supply chain, revealing previously unrecognized levels of seafood fraud, raising awareness among the public, and serving as a warning to industry that malpractice will be detected. Here we present the outcome of the latest and largest multi-species, transnational survey of fish labeling accuracy to date, which demonstrates an apparent sudden reduction of seafood mislabeling in Europe. We argue that recent efforts in legislation, governance, and outreach have had a positive impact on industry regulation. Coordinated, technology-based, policy-oriented actions can play a pivotal role in shaping a transparent, sustainable global seafood market... |

| Surimi is a japanese term refering to minced and thoroughly washed fish meat. Quality of surimi is determined by its ability to form a firm and elastic gel after heat treatment. The parameters affecting this property are : fish species, storage before further processing (refrigeration, icing, freezing), addition of cryoprotectors limiting the protein denatura during freeze storage, addition of texturing agent such as starch and egg white. The effects of some of these parameters have been studied on Whiting-pout surimi (Trisoptesus Luscus). Water content of surimi has a great influence on kamaloko quality. Increase ,in starch and egg white concentration does not improve gel quality in terms of rigidity and cohesiveness. A ten day storage of whiting-pout on... |

| The sea lamprey Petromyzon marinus, which is among the most phylogenetically ancient vertebrates, is a hematophagous ectoparasite that feeds on vertebrates and is considered vulnerable in Europe but is a pest in the North American Great Lakes. We conducted a literature review of helminth parasites of Petromyzon marinus and investigated postmetamorphic lampreys sampled in rivers and northeast Atlantic coastal waters (western France) during spawning migration. Based on the literature review, 16 helminth taxa have been recorded in Petromyzon marinus, among them 14 in North America but only 2 in Europe, with no species in common between these areas. Specific parasites are lacking, and helminth parasites recorded in Petromyzon marinus are mostly opportunistic... |

| A better knowledge on spawning grounds of principal commercial fishes from North Sea is necessary for their monitoring. Fish egg taxonomic identification based on morphological characters cannot always be carried out effectively. This is particularly the case for a number of Gadidae fish species eggs (i.e. cod, haddock and whiting, and three rockling species) which have the same range of size and for which molecular-based techniques can help improving the accuracy of egg taxonomic identification, and hence the reliability of studies on spawning areas. In this study, formalin fixation, egg conservation and DNA extraction were optimized in order to develop a specific PCR-RFLP method. Based on the sequence of the cytochrome b gene of reference specimens, a... |

| A la question : Qu'est-ce que le surimi ?, l'introduction du rapport annuel d'activité de juin 1985 "Essais préliminaires et premleres études de l'influence des paramètres technologiques sur la texture du surimi et gel de surimi de chinchard (Trachurus trachurus)" a tenté d'apporter une réponse. Après le détail de la fabrication du surimi employée ainsi que les résultats de quelques essais préliminaires permettant de choisir les méthodes de mesures adéquates, nous avions abordé la premiere grande partie du travail - l'optimisation des conditions technologiques - et indiqué les prémices d'une étude sur la microstructure du surimi et du kamaboko. Actuellement la première partie de l'étude est terminée et deux articles "Texture du kamaboko de chinchard... |

| This report describes a set of 21 polymerase chain reaction primers and amplification conditions developed to barcode practically any teleost fish species according to their mitochondrial cytochrome b and nuclear rhodopsin gene sequences. The method was successfully tested in more than 200 marine fish species comprising the main Actinopterygii family groups. When used in phylogenetic analyses, its combination of two genes with different evolutionary rates serves to identify fish at the species level. We provide a flow diagram indicating our validated polymerase chain reaction amplification conditions for barcoding and species identification applications as well as population structure or haplotyping analyses, adaptable to high-throughput analyses. |
