This study analyses the microbiological changes with traditional methods for total mesophilic aerobic, psychrotrophic, Aeromonas sp., Pseudomonas sp., Shewanella putrefaciens, Enterobacteriaceae, sulfide-reducing Clostridium and Photobacterium phosphoreum in muscle, skin and gills of whole ungutted gilthead sea bream (Sparus aurata) stored in ice during 18 days. The muscle tissue showed the min...

Sinanoglou V., Houhoula D., Kyrana V., Lougovois V. (2017): Visceral oil from farmed Sparus aurata, Dicentrarchus labrax and Diplodus puntazzo as a source of ω-3 PUFA. Czech J. Food Sci.,35: 414–423. Crude oils recovered from the viscera of conventionally and organically farmed gilthead sea bream (Sparus aurata), European seabass (Dicentrarchus labrax), and sharpsnout sea bream (Diplodus puntaz...

The nuclear DNA content in Dicentrarchus labrax, Sparus aurata, Liza ramada, and Anguilla anguilla, was measured by flow cytometric analysis. Male human leukocytes were used as internal reference cells. Nucleated fish erythrocytes were stained simultaneously to human leukocytes with a staining buffer containing propidium iodide (PI). Nuclear DNA contents of target species were estimated in rela...

The main source of calcium carbonate (CaCO₃) in the ocean comes from the shells of calcifying planktonic organisms, but substantial amounts of CaCO₃ are also produced in fish intestines. The precipitation of CaCO₃ assists fish in intestinal water absorption and aids in whole body Ca²⁺ homeostasis. Here we report that the product formed in the intestinal lumen of the gilt-head seabream, Sparus a...

The population dynamics of pseudomonads in gilt-head sea bream Mediterranean fish (Sparus aurata) stored under different conditions were studied. Phenotypic analysis and sodium dodecyl sulfate-polyacrylamide gel electrophoresis of whole-cell proteins were performed to identify a total of 106 Pseudomonas strains isolated from S. aurata stored under different temperatures (at 0, 10, and 20 degree...

The radiological differences between the urinary tract of  Dicentrarchus labrax, Sparus aurata, Tinca tinca, and Cyprinus carpio are shown. In fresh water teleosts the urinary bladder is sigmoid and a short urethra leads to the urinary pore. Genital and anal pores are present. In Sparus aurata the urinary bladder has a globoid shape. In Dicentrarchus labrax the urinary bladder is smaller and el...

Using antisera to regions of human parathyroid hormone-related protein (PTHrP) the saccus vasculosus (SV) of the sea bream (Sparus aurata) has been shown to contain immunoreactive PTHrP. By immunohistochemistry (IHC) the epithelial coronet cells in fixed and wax-embedded SV tissue reacted with antisera to the prepro region of human PTHrP (-13 to +2), the N-terminus PTHrP (1-16), and the midmole...

Neurotoxicity induced in fish by domoic acid (DA) was assessed with respect to occurrence of neurotoxic signs, lethality, and histopathology by light microscopy. Sparus aurata were exposed to a single dose of DA by intraperitoneal (i.p.) injection of 0, 0.45, 0.9, and 9.0 mg DA kg(-1) bw. Mortality (66.67 ± 16.67%) was only observed in dose of 9.0 mg kg(-1) bw. Signs of neurological toxicity we...
