Tenacibaculum adriaticum B390 is isolated from the bryozoan Schizobrachiella sanguinea from the Adriatic Sea. The Adriatic Sea is part of the Mediterranean Sea and is positioned between the eastern coastline of Italy, and countries of the Balkan Peninsula, from Slovenia, south through Croatia.(3) The Adriatic Sea is about 500 miles (800 km) long, northwest-southeast, and up to 140 miles (225 km) wide. It has an area of approximately 51,000 square miles (132,000 km 2 ), slightly less than that of Lakes Superior and Michigan combined. The Adriatic is one of the shallowest parts of the Mediterranean, with an average depth of about 800 feet (240 m). The deepest spot, 4,034 feet (1,230 m), is about midway between Bari, Italy, and the coast of Montenegro. (4) ...

Predatory bacteria are ubiquitous in aquatic environments and may be important players in the ecology and biogeochemistry of microbial communities. Three novel strains belonging to two genera of marine flavobacteria, Olleya and Tenacibaculum, were cultured from coastal sediments and found to be predatory on other bacteria on surfaces. Two published species of the genus Tenacibaculum were also observed to grow by lysis of prey bacteria, raising the possibility that predation may be a widespread lifestyle amongst marine flavobacteria, which are diverse and abundant in a variety of marine environments. The marine flavobacterial clade is known to include species capable of photoheterotrophy, scavenging of polymeric organic substances, pathogenesis on animals, the degradation and lysis of phytoplankton blooms and, now, predation on bacterial communities. Strains from the two genera were found to exhibit divergent prey specificities and growth yields when growing predatorily. Olleya sp. predatory ...

Retinal photodamage has previously been studied in teleost fish but very few have been performed on aquaculture species. To study retinal damage, Atlantic cod (Gadus morhua), Atlantic salmon (Salmo salar) and European sea bass (Dicentrarchus labrax) were previously acclimated to a control 12L:12D photoperiod with standard experimental low light intensity (0.1 W/m(2), equivalent to 3.2 x 10(13) photons/s/cm(2)) for at least 4 weeks and then kept under constant darkness (DD) for 3 days. Thereafter, fish were exposed to continuous high intensity light (51-380 W/m(2), equivalent to 1.63 x 10(16)-1.22 x 10(17) photons/s/cm2) for 3, 7, 15 or 25 days before returning to a control 12L:12D photoperiod (same intensity than during acclimation period) to study retinal regeneration over a period of 30 days. Retinal damage was exclusively assessed through the analysis of morphometric parameters. Results showed the presence of light-induced damage in the three species examined, as well as recovery once the ...

The aim of the study was to validate a dummy regression approach for predictive modelling the fillet fatty acid (FA) composition of cultured European sea bass with dietary FA composition and lipid fillet content as independent variables. The model used our own data on gilthead sea bream as reference subgroup dataset and data from turbot, sole and European sea bass as dummy variables. Most of the observed variance within and among species was explained by the regression model without statistical significant interactions on blocks between diet composition and fish species subgroups. For the validation of European sea bass FA descriptors, predictive values derived from data on fish reared at laboratory scale were plotted against those obtained in farmed fish harvested at commercial size. A close linear association near to equality was found for 12 representative FAs, including saturated FAs, monoenenes and polyunsaturated FAs. This finding reinforces the possibility to produce tailored and healthy ...

Locomotor ability is a key organismal performance trait in the chain of interactions that link biochemical, morphological and physiological traits to fitness (Arnold, 1983). For many species, essential ecological functions such as predator-prey interactions, reproductive activities or foraging, are dependent upon an animals capacity for movement. The intuitive recognition of this relationship has led to a consistent interest in fish locomotion among scientists, but the nature of the relationship between locomotion and fitness remains largely unknown for most fish species.. The study of fish locomotion began in earnest around 60 years ago (e.g. Black, 1955; Bainbridge, 1958a; Bainbridge, 1958b; Brett, 1964; Fry, 1971; Beamish, 1978) but there are still large gaps in our understanding of the elements that determine swimming performance. For instance, the nature of maximal swimming performance as well as the factors which contribute to the transition between aerobic and anaerobic swimming modes, ...

DMRT1 is conserved from invertebrates to human and has been implicated in sex differentiation and testis function in many organisms. We report the cloning of two DMRT1 transcripts, DMRT1a and DMRT1b, encoded by a single gene in the European sea bass, Dicentrarchus labrax, a teleost fish with polygenic sex determination influenced by temperature. DMRT1a and DMRT1b are specific to the testis and are ...

Coldwater-associated ulcers, i.e. winter ulcers, in seawater-reared Atlantic salmon Salmo salar L. have been reported in Norway since the late 1980s, and Moritella viscosa has been established as an important factor in the pathogenesis of this condition. As routine histopathological examination of winter ulcer cases in our laboratory revealed frequent presence in ulcers of long, slender rods clearly different from M. viscosa, a closer study focusing on these bacteria was conducted. Field cases of winter ulcers during 2 sampling periods, 1996 and 2004-2005, were investigated and long, slender rods were observed by histopathological examination in 70 and 62.5% of the ulcers examined, respectively, whereas cultivation on marine agar resulted in the isolation of yellowpigmented colonies with long rods from 3 and 13% of the ulcers only. The isolates could be separated into 2 groups, both identified as belonging to the genus Tenacibaculum based on phenotypic characterization and 16S rRNA sequencing. ...

Purpose: Teleost is a successful vertebrate group, constituting more than 50% of vertebrate species. These fishes are the only vertebrate group that presents spinules from the lateral dendrites of Cone Horizontal Cells into cone pedicles. Previously, we observed that the number of spinules in any given species depended on both taxonomic placing and degree of predatory behavior. Then, species with the most spinules were also the most predatory and vice versa. The aim of this work was to study the density of spinules and synaptic ribbons, per cone pedicle, in central and peripheral retina.. Methods: The study was performed on European sea bass (Dicentrarchus labrax), one specie of teleost fish belonging to perciform order and moronidae family. Light-adapted fishes were sacrificed. Retinas were extracted and whole mounts embedded in EPON for transmission-electron-microscopy study. Thin sections from eight representative retinal areas were observed and photographed in an Electron Microscope. The ...

Tenacibaculum maritimum is a devastating bacterial pathogen of wild and farmed marine fish with a broad host range and a worldwide distribution. We report here the complete genome sequence of the T. maritimum type strain NCIMB 2154T. The genome consists of a 3,435,971-base pair circular chromosome with 2,866 predicted protein-coding genes. Genes encoding the biosynthesis of exopolysaccharides, the type IX secretion system, iron uptake systems, adhesins, hemolysins, proteases, and glycoside hydrolases were identified. They are likely involved in the virulence process including immune escape, invasion, colonization, destruction of host tissues, and nutrient scavenging. Among the predicted virulence factors, type IX secretion-mediated and cell-surface exposed proteins were identified including an atypical sialidase, a sphingomyelinase and a chondroitin AC lyase which activities were demonstrated in vitro.

That experience is a valuable base for the partners, and associated partners, to analyse the use cases and to elaborate the implementation process in the partner countries (Portugal; Spain; Uk; Ireland and France).. Euroshore and its members, in particular Eco-oil, have worked to set out best solutions to deal with oil and other ships effluents. The feedback on these works, and their perception on new issues such as BW is another pillar for future works of the partners: what could be improved, especially on an economic and regulatory point of view.. Around these two groups, the port authorities and scientific organizations presented their own works, advances and results regarding in particular the protection of the environment. The EU, and particularly the DG Mare, has there been a federative agency, providing funds and support to develop years after years databases, charts and models of European sea waters. Thats another pillar of project, which intends to complete that work, focusing on port ...

Counting every single fish in the European seas may sound as likely as finding a mermaid, but it seems the world of technology has no boundaries.

The teleost brain is characterized by exceptionally high levels of aromatase, the enzyme that converts androgens into estrogens, and by its continuous growth throughout life. Gonadal estrogens have been implicated in sex differentiation and the control of reproduction in adult fish, but the role of neural estrogens during early development is far from clear. The present study describes the isolation and characterization of the cDNA sequence from brain aromatase (P450aromB) in the European sea bass (Dicentrarchus labrax L.), a well established model for neuroendocrine research in fish. P450aromB was cloned from a brain cDNA library and encoded a predicted protein of 505 residues, with a calculated molecular weight of 57.2 kDa. Comparisons of the deduced amino acid sequence to that of the ovarian aromatase (P450aromA) in the same species revealed 62% identity, lower than the 84% identity shared between sea bass and tilapia brain aromatases. Phylogenetic analysis showed the occurrence of a gene ...

Marine fish species exhibit low capacity to biosynthesise highly unsaturated fatty acid (HUFA) in comparison to strict freshwater and anadromous species. It is admitted that the Delta(6) desaturase (FADS2) is a key enzyme in the HUFA biosynthetic pathway. We investigated by quantitative PCR the relative amounts of FADS2 mRNA in European sea bass (Dicentrarchus labrax) in comparison with a salmonid species, the rainbow trout (Oncorhynchus mykiss L.). The analysis of the expression data was performed regarding the difference of the characteristics of a critical fragment of the fads2 gene promoter between sea bass and Atlantic salmon. The lower level of fads2 gene expression observed in sea bass suggested that fads2 gene putative promoter, which exhibited an E-box like Sterol Regulatory Element (SRE) site but lacked a Sp1 site, is less active in this marine species. The cytosine methylation of CpG sites in the putative promoter region including E-box like SRE and NF-Y binding sites of sea bass fads2 gene

The monoclonal antibody (Mab) against Nodavirus (also know as VNN) is specific for this virus. The MAb has been tested by ELISA with Betanodavirus isolated from four different fish species, including European Sea Bass, Atlantic cod, halibut and Striped Jack.The Mab reacted with Nodavirus isolated from European Sea Bass that has been shown to belong to the RGNNV (red spotted groupe rnervous necrosis virus) cluster. It also reacted against Nodavirus isolated from Atlantic cod and halibut that have been shown to belong to the BFNNV (Barfin flounder nervous necrosis virus) cluster. The Mab did not react with SJNNV (striped jack nervous necrosis virus). SJNNV has been shown to be phylogenetically quite different to the other Nodavirus clusters.. ...

A fishs sense of smell is a pretty cool phenomenon. Unfortunately, though, climate change is harming the olfactory capabilities of many fish living in our oceans.. According to EcoWatch, carbon dioxide released from carbon emissions mixes with seawater to create a harmful substance called carbonic acid.. In a collaborative study, researchers in Portugal and the UK found that European sea bass living in highly acidic waters didnt respond to the smell of a predator.. Granted, this experiment took place in waters which are about two times more acidic than todays oceans. However, the test aligns with predictions about carbon dioxide levels in Earths oceans by the end of the 21st century.. This is an alarming fact to note, considering that 75% of life on earth lives underwater. Not only does this affect the fish themselves, but it affects us as well.. Three billion people, just under half of the current total human population, rely on seafood for 20% of their protein intake.. The researchers ...
