| contribution to the knowledge of species of the genus stephanostomum looss, 1899 (digenea: acanthocolpidae) from teleosts of the western mediterranean, with the description of s. gaidropsari n. sp. | four species of the acanthocolpid genus stephanostomum are redescribed from the digestive tract of teleosts in the western mediterranean: the type-species, s. cesticillum from lophius piscatorius is described with a ventrally interrupted ring of 35 circum-oral spines and as lacking a uroproct; s. bicoronatum from sciaena umbra has a ventrally interrupted ring of 31 circum-oral spines and a uroproct; s. pristis from phycis phycis has an uninterrupted ring of 36 oral spines and no uroproct; s. min ... | 2001 | 11466478 |
| anisakid parasites of two forkbeards (phycis blennoides and phycis phycis) from the mediterranean coasts of andalucía (southern spain). | an epidemiological survey of anisakids was carried out on 209 specimens of greater forkbeard (phycis blennoides) and 58 of forkbeard (phycis phycis) captured off the mediterranean coasts of andalucía (southern spain). four species of nematodes were identified: anisakis simplex s.l., anisakis physeteris, hysterothylacium aduncum and hysterothylacium fabri. the total prevalence was 62.06% in the forkbeard and 58.85% in the greater forkbeard. the highest values of prevalence (56.90%), mean intensit ... | 2006 | 16168705 |
| anisakid parasites of two forkbeards (phycis blennoides and phycis phycis) from the eastern mediterranean coasts in tunisia. | two gadiform species with a successive bathymetric and an ecological and economical importance in the mediterranean fishing industry, phycis blennoides and phycis phycis, were selected for the present study. a total of 592 fresh specimens belonging to the gadiformes genus were obtained from local commercial fisheries. the investigation was centred on anisakid parasites of 272 specimens of the greater forkbeard (p. blennoides) and 320 of the forkbeard (p. phycis) captured off the mediterranean co ... | 2006 | 16847607 |
| intra- and inter-specific variability in total and methylmercury bioaccumulation by eight marine fish species from the azores. | we relate fish biological and ecological characteristics to total and organic mercury concentrations to determine whether accumulation is influenced by trophic level, hg concentration in the diet, and vertical distribution. levels of total mercury and methylmercury were determined in the muscle tissue of eight species of fish: pagellus acarne, trachurus picturatus, phycis phycis, p. blennoides, polyprion americanus, conger conger, lepidopus caudatus and mora moro, caught in the azores. all such ... | 2007 | 17727898 |
| site influence in parasite distribution from fishes of the bonifacio strait marine reserve (corsica island, mediterranean sea). | the spatial distribution of parasite communities from teleost fishes (diplodus vulgaris, mullus surmuletus, pagellus erythrinus, phycis phycis, scorpaena scrofa and symphodus tinca) was studied in the bonifacio strait marine reserve (corsica island) with different protection levels. canonical correspondence analysis was used to study spatial patterns and to quantify the importance of site influence on parasite communities. to supplement these results, we used the indicator species analysis (indv ... | 2009 | 19132390 |
