| systematics of scorpaeniformes species in the mediterranean sea inferred from mitochondrial 16s rdna sequence and morphological data. | genetic and morphological divergence and phylogenetic relationships of scorpaeniformes fish including two genera and six species, helicolenus dactylopterus, scorpaena maderensis, scorpaena porcus, scorpaena elongata, scorpaena scrofa, scorpaena notata, living in the mediterranean sea, were investigated with morphological and mitochondrial 16s rdna sequence data. the mean nucleotide diversity was found to be 0.0792. average sequence divergence between species of sebastidae and scorpaenidae was 8. ... | 2009 | 19777968 |
| total mercury in muscle of benthic and pelagic fish from the south adriatic sea (italy). | total mercury concentrations were measured from the muscle of different kinds of fish: yellow gurnard (trigla lucerna), red gurnard (aspitrigla cuculus) red fish (helicolenus dactylopterus), skate spp. (raje spp.), goldline (sarpa salpa), atlantic bonito (sarda sarda), mackerel (scomber scombrus), chub mackerel (scomber japonicus) caught in the south adriatic sea (south italy) in the period june/august 1995. the highest total mercury levels were found in the benthic marine organisms and particul ... | 1998 | 10366996 |
| [a new acanthocephala breizacanthus ligur sp. n. (palaeacanthocephala: arhythmacanthidae yamatugi, 1935) parasite of some species of benthic fishes from the ligurian sea]. | breizacanthus ligur sp.n. is described and figured from several benthic fishes from the ligurian sea. the host species are: argentina sphyraena, chlorophthalmus agassizi, gadiculus argenteus, phycis blennoides, coelorhynchus coelorhynchus, capros aper, callionymus phaeton, helicolenus dactylopterus. the parasites were considered as belonging to the family arhythmacanthidae yamaguti, 1935 and to the genus breizancanthus golvan, 1969. breizancanthus ligur differs from the only two known species of ... | 2006 | 1233404 |
| a new species of microcotyle (monogenea: microcotylidae) from scorpaena notata (teleostei: scorpaenidae) in the mediterranean sea. | we collected specimens of microcotyle spp. from two species of scorpaeniform fishes off algeria, namely scorpaena notata and helicolenus dactylopterus. the identification of both fishes was confirmed by molecular barcoding of the coi gene. sequences of coi gene were also obtained for both parasite species. the species from s. notata is described as microcotyle algeriensis n. sp., on the basis of morphological differences from other species (number of clamps, number of spines in genital atrium, n ... | 2017 | 27840197 |
| dna damage, severe organ lesions and high muscle levels of as and hg in two benthic fish species from a chemical warfare agent dumping site in the mediterranean sea. | the aim of the present study was to evaluate the environmental threat to benthic species from chemical weapons dumped in the southern adriatic sea. an ecotoxicological approach using chemical analysis and biological responses was applied, in two sentinel species: the blackbelly rosefish helicolenus dactylopterus and european conger conger conger. specimen were collected in a stretch of sea, where had been dumped war materials and from a reference site free of ordnance. residues of yperite, hg an ... | 2010 | 20083295 |
| comparing deep-sea fish fauna between coral and non-coral "megahabitats" in the santa maria di leuca cold-water coral province (mediterranean sea). | two experimental longline surveys were carried out in the santa maria di leuca (sml) cold-water coral province (mediterranean sea) during may-june and september-october 2010 to investigate the effect of corals on fish assemblages. two types of "megahabitat" characterized by the virtual absence of fishing were explored. one was characterized by complex topography including mesohabitats with carbonate mounds and corals. the other type of megahabitat, although characterized by complex topographic f ... | 2012 | 23028551 |
| assessment of the essential element and heavy metal content of edible fish muscle. | the aim of this work was to determine the concentrations of some essential and toxic elements in the muscle of ten species of commercial fish consumed in portugal. we combined two different techniques for determination of the elements--energy-dispersive x-ray fluorescence (edxrf) was used to quantify k, ca, fe, zn, se, rb, and sr and flame atomic-absorption spectrometry for analysis of cr, ni, cu, cd, hg, and pb. the latter technique was used because of its higher sensitivity, because these elem ... | 2005 | 15830192 |
