The antibacterial activity present in the s k ~ n mucus of turbot Scophthalmus maximus, seabream Sparus aurdtd and seabass Dicentrarchus labrdx against Pasteul-ella piscicida and Flex~bacter maritimus was evaluated. Using assays on agar plates, none of the mucus samples from the above fish showed any antibacterial activity against E maritimus isolates. Turbot mucus inhibited the growth of the P...

Hatchery-reared turbot (Scophthalmus maximus L.) were exposed for 3 weeks, under laboratory conditions, to sediment collected from polluted sites in Cork Harbour and a reference site at Ballymacoda, Co. Cork, Ireland. The potential of surficial sediment for inducing hepatic biomarkers was assessed at two levels of biological organisation: expression of cytochrome P450 [Western blotting analysis...

Experimental infection with Pseudomonas anguilliseptica was performed both by intraperitoneal (i.p.) and bath route on juvenile turbot (Psetta maxima) in order to evaluate the pathology induced. Turbot was found to be sensitive to i.p. challenge (1.7x10(6) CFU/fish) but no to bath exposure. The i.p. challenge induced septicaemic infection and mortality. Externally, moribund fish showed distende...

As part of a regionwide collaboration to determine the occurrence of contaminants and biological effects in coastal ecosystems offshore of urban southern California, the present study characterized the reproductive endocrinology of an indigenous flatfish, the hornyhead turbot (Pleuronichthys verticalis), and compared groups sampled from different study sites representing varying degrees of poll...

The turbot (Scophthalmus maximus) is a commercially valuable flatfish and one of the most promising aquaculture species in Europe. Two transcriptome 454-pyrosequencing runs were used in order to detect Single Nucleotide Polymorphisms (SNPs) in genes related to immune response and gonad differentiation. A total of 866 true SNPs were detected in 140 different contigs representing 262,093 bp as a ...

Turbot is one of the most important farmed fish in Europe. This species exhibits a considerable sexual dimorphism in growth and sexual maturity that makes the all-female production recommended for turbot farming. Our knowledge about the genetic basis of sex determination and the molecular regulation of gonad differentiation in this species is still limited. Our goal was to identify and compare ...

This work reports on the antigenic characterization and virulence for rainbow trout Oncorhynchus rnykiss of Vibrio anguillarurn-related (VAR) strains isolated from diseased turbot Scophthal1nus maximus and cod Gadus niorhua in Spain and Denmark. These vibrio strains belong to Mbrio splendldus biovar 1 (serogroups B , C , D, F and G) and pelagius biovar I (serogroup A). The pathogenicity assays ...

Aeromonas salmonicida subsp. is the causative agent of furunculosis, a disease affecting numerous fish species worldwide. It highly pathogenic bacterium for turbot, whose farming production represents an important economic activity in several European countries and China. To better understand response this organism to A. , we conducted RNA-Seq analysis head kidney from experimentally infected u...

Two 70-day feeding trials were conducted to reevaluate the necessity of cholesterol supplementation in diets two important marine fish species, turbot and tiger puffer. Graded levels (0, 0.5, 1.0, 2.0, 4.0% dry matter) added into basal diet (with 30% fishmeal but no oil) make five experimental diets, which designated as control, CHO-0.5, CHO-1.0, CHO-2.0, CHO-4.0, respectively. The dietary conc...
