Abstract The fish acanthocephalan fauna of Turkish waters is poorly known. In this study 8 fish species (Merluccius merluccius, Trachurus trachurus, Uranoscopus scaber, Gobius niger, G. cobitis, Scorpaena scrofa, Eutrigla gurnardus, Solea vulgaris) were collected from Gemlik Bay and examined for their acanthocephalan fauna. Four species not previously recorded in fish of Turkish waters were found: Solearhynchus soleae (Echinorhynchidae), Acanthhocephaloides propinquus, Paracanthocephaloides kostylewi (Arhythmacanthidae), and Longicollum pagrosomi (Pomphorhynchidae). The most common species was A. propinquus, a parasite that infects mostly gobiids (G. niger, G. cobitis). Longicollum pagrosomi was a new record for the Mediterranean basin.

Background and Objectives: In this article a comprehensive study was carried out for the determination of natural radioactivity in Mediterranean sea fishes and the evaluation of radiological health risks due to their ingestion. All analyzed samples came from the Calabria region, southern Italy, and, in particular, from the district of Reggio Calabria. Method: A total of seventy representative samples, five for each investigated species (Sardina Pilchardus, Mugil Cephalus, Scomber Scombrus, Sparus Aurata, Dicentrarchus Labrax, Tonnus Thynnus, Thunnus Alalunga, Xiphaias Gladius, Pagellus Erythrinnus, Engraulis Encrasicholus, Belone Belone, Solea Solea, Merluccius Merluccius, Mullus Surmuletus) were analyzed through HPGe gamma spectrometry. The evaluation of dose levels and lifetime cancer risks for adult members of the population due to the fishes ingestion was also performed. Results: The specific activity of 40K was investigated and its mean value was found to be: (157 ± 17) for Sardina Pilchardus, (138 ± 14) for Mugil Cephalus, (118 ± 13) for Scomber Scombrus, (128 ± 14) for Sparus Aurata, (146 ± 17) for Dicentrarchus Labrax, (93 ± 11) for Tonnus Thynnus, (137 ± 15) for Thunnus Alalunga, (98 ± 10) for Xiphaias Gladius, (105 ± 12) for Pagellus Erythrinnus, (132 ± 14) for Engraulis Encrasicholus, (113 ± 12) for Belone Belone, (34 ± 5) for Solea Solea, (76 ± 9) for Merluccius Merluccius and (96 ± 11) for Mullus Surmuletus, respectively. Conclusions: The committed effective dose and the lifetime cancer risks for adult members of the population due to the consumption of the investigated samples are lower than the average world value, the maximum acceptable level and the allowed range, respectively. It can then be concluded that the Mediterranean sea fishes consumed in the study area pose no significant health risks to the population from a radiological point of view.

Fish authentication is a major concern not only for the prevention of commercial fraud, but also for the assessment of safety risks deriving from the undeclared introduction of potentially dangerous toxic or allergenic substances or environmentally damaging fish where endangered species are involved. Moreover, food authentication might affect the diet of certain groups of consumers, such as followers of religious practices. Considering the authentication of fish products is one of the key issues in food safety, quality and sustainability, the aim of this work was to investigate the prevalence of mislabelling in sole (<em>Solea solea</em>), plaice (<em>Pleuronectes platessa</em>), Atlantic salmon (<em>Salmo salar</em>), and hake (<em>Merluccius merluccius</em>) fillets from markets and supermarkets located in Apulia (Southern Italy) using DNA barcoding. The results of the molecular investigations reveal that 42/98 (42.8%) fillet samples were not correctly labelled. In particular, 12/27 (44.4%) fillets of sole (<em>Solea solea</em>) were identified as belonging to Solea senegalensis. In addition, 13/28 (46.4%) plaice (<em>Pleuronectes platessa</em>) samples were identified as Pangasius hypophtalmus. All Atlantic salmon (<em>Salmo salar</em>) samples were correctly labelled. Post-sequencing data analysis revealed that 17/30 (56.6%) hake fillets (<em>Merluccius merluccius</em>) were not correctly labelled, of which 8/30 samples identified as <em>Merluccius hubbsi</em>, 5/30 samples as Merluccius products and 4/30 as <em>Merluccius capensis</em>. The study reveals a high occurrence of species mislabelling in the prepared fish fillet products, further evidence of the need for increased traceability and assessment of the authenticity of food products.

ABSTRACT Mycobacteria were isolated from defrost water and tissue of sole (Solea solea), hake (Merluccius merluccius), cod (Gadus morhua), ling (Genypterus blacodes), and monkfish (Lophius piscatorius) on Löwenstein-Jensen medium after incubation at different temperatures. Samples of frozen fish were obtained under sterile conditions inside a refrigeration chamber (−18 to −22°C) in a wholesale market from which these products are distributed to shops for retail sale and human consumption.

Clestobothrium Crassiceps

AbstractVitellogenesis and vitellocytes of the bothriocephalidean cestode Clestobothrium crassiceps (Rudolphi, 1819), a parasite of the teleost fish Merluccius merluccius (L., 1758), were studied by means of transmission electron microscopy (TEM) and cytochemistry. During vitellogenesis, four developmental stages were distinguished at the TEM level: (I) a stem cell stage of the gonial type; (II) an early differentiation stage, predominantly exhibiting lipid and protein synthetic activity; (III) an advanced differentiation or vitellocyte maturation stage, primarily exhibiting active glycogenesis still accompanied by an increase in lipid accumulation; and (IV) a mature vitellocyte stage. Vitellogenesis involves: (1) an increase in cell volume; (2) an extensive development of parallel, frequently concentrically arranged, cisternae of granular endoplasmic reticulum (GER) that produce dense, proteinaceous shell-gobules; (3) the development of Golgi complexes engaged in the packaging of this material; (4) an accelerated accumulation of unsaturated and saturated lipid droplets, along with their continuous enlargement and fusion; (5) the formation of individual β-glycogen particles and α-glycogen rosettes and their accumulation in the form of glycogen islands scattered among lipid droplets in the cytoplasm of maturing and mature vitellocytes; and (6) the rapid accumulation of large, saturated lipid droplets accompanied by dense accumulations of α- and β-glycogen along with proteinaceous shell-globules or shell-globule clusters in the peripheral layer during the advanced stage of vitellocyte maturation. Vitellogenesis in C. crassiceps generally resembles that previously described for three other bothriocephalideans, but differs from that of other cestode orders. Cytochemical staining with periodic acid-thiocarbazide-silver proteinate for glycogen indicates a strongly positive reaction for β-glycogen particles and α-glycogen rosettes, which form several large glycogen accumulations around the large, saturated lipid droplets of maturing and mature vitellocytes. Some hypotheses concerning the interrelationships between patterns of vitellogenesis, the possible modes of egg formation, embryonic development and life cycles in cestodes, and their phylogenetic implications are commented upon.
