Antibacterial drugs in products originating from aquaculture: assessing the risks to public welfare
(2010)As aquaculture expands to meet human demand and compensate for pessimistic forecasts of fisheries catches, use of antibacterial agents to combat or forestall bacterial diseases is still a necessity, although effective ... -
Comparison of heavy metal concentrations in fish samples from three fish farms (Eastern Mediterranean) utilizing antifouling paints
(2015)Although aquaculture is considered the fastest growing food production industry, nevertheless there is little information regarding pollutant levels in cultured fish. Samples of cultured sea bass - Dicentrarchus labrax ... -
Fish farming and anti-fouling paints: a potential source of Cu and Zn in farmed fish
(2014)The accumulation of copper and zinc, the basic components of anti-fouling paints, was examined in cultured sea bass Dicentrarchus labrax and sea bream Sparus aurata. Samplings were carried out at 4 eastern Mediterranean ... -
Fish farming effects on local fisheries landings in oligotrophic seas
(2006)The effects of fish-farming on local landings in five regions of the Aegean and Ionian Seas (eastern Mediterranean basin) were analysed, together with certain parameters related to environmental changes and fishing fleet ... -
Interconnectivity vs. isolation of prokaryotic communities in European deep-sea mud volcanoes
(2013)During the past two decades, European cold seep ecosystems have attracted the scientific interest and to date there are several studies which have investigated the community structure and biodiversity of individual sites. ... -
A non-phylogenetic alpha diversity approach on prokaryotic community structure in aquatic systems
(2013)Comparative analyses of accumulating phylotype-abundance data of prokaryotic communities are relatively scarce and mainly approached with phylogenetic methodologies. However, when a great fraction of phylotypes is captured ... -
Poor bioavailability of oxytetracycline in sharpsnout sea bream Diplodus puntazzo
(2004)The pharmacokinetics of oxytetracycline (OTC) were investigated following single intravascular injection (40 mg/kg) in sharpsnout sea bream (90 g) at 19 degreesC. The distribution half-life (t(1/2alpha)) and the elimination ... -
Prokaryotic community structure and diversity in the sediments of an active submarine mud volcano (Kazan mud volcano, East Mediterranean Sea)
(2010)We investigated 16S rRNA gene diversity at a high sediment depth resolution (every 5 cm, top 30 cm) in an active site of the Kazan mud volcano, East Mediterranean Sea. A total of 242 archaeal and 374 bacterial clones were ... -
Spatial monitoring of arsenic and heavy metals in the Almyros area, Central Greece. Statistical approach for assessing the sources of contamination
(2015)The purpose of this work was to provide information on As and heavy metals content in surface soils of the Almyros area, in Central Greece. A 3-year (2009-2011) research was conducted, in order to investigate the possible ... -
Variability of Prokaryotic Community Structure in a Drinking Water Reservoir (Marathonas, Greece)
(2012)The structure of the Bacteria and Archaea community in a large drinking water reservoir (Marathonas, Greece; MR) was investigated in October 2007 and September 2008, using 16S rRNA gene clone libraries. The bacterial ...
