| 'cebiche'--a potential source of human anisakiasis in mexico? | five fish species used for preparation of a popular dish (cebiche) made with raw fish flesh in mexico were obtained from five localities of the coast of yucatan. lutjanus synagris, gerres cinereus, sphyraena barracuda, epinephelus morio and haemulon plumieriwere examined for the presence of larvae of anisakid nematodes, causative agents of human anisakiasis. the nematode pseudoterranova sp. was found in e. morio and s. barracuda with a total prevalence of 83% and 6.5 +/- 6.2 worms per fish for e ... | 2000 | 10881286 |
| interoceanic occurrence of species of aristocleidus mueller, 1936 (monogenoidea: dactylogyridae) parasitizing the gills of gerreid fishes in the neotropics. | during investigations of fish parasites in the neotropics (including the state of veracruz and the yucatán peninsula in the gulf of mexico, the chautengo lagoon on the pacific coast of the state of guerrero in mexico, and lake gatun in the panama canal), three monogenoidean (dactylogyridae) species were found parasitizing the gills of gerreids (gerreidae): aristocleidus hastatus mueller, 1936, was recovered from eugerres plumieri (cuvier) and diapterus auratus ranzani in veracruz, from d. auratu ... | 2009 | 19415330 |
| lead in clams and fish of dietary importance from coatzacoalcos estuary (gulf of mexico), an industrialized tropical region. | with the aim of knowing seasonal variability of lead in fish and bivalve species from coatzacoalcos estuary, biota collected during three seasons was examined. in muscle tissue of fish, the highest level (5.4 microg g(-1)) was found in the longnose gar lepisosteus osseus from san francisco stream (a highly impacted site); the lowest value (0.2 microg g(-1)) was registered in yellowfin mojarra gerres cinereus from ostión lagoon (control site). in bivalves, concentrations in soft tissue ranged fro ... | 2007 | 17924041 |
| seasonal blood chemistry response of sub-tropical nearshore fishes to climate change. | climate change due to anthropogenic activity will continue to alter the chemistry of the oceans. future climate scenarios indicate that sub-tropical oceans will become more acidic, and the temperature and salinity will increase relative to current conditions. a large portion of previous work has focused on how future climate scenarios may impact shell-forming organisms and coral reef fish, with little attention given to fish that inhabit nearshore habitats; few studies have examined multiple cha ... | 2014 | 27293649 |
| prey selection and functional response of juvenile lemon sharks negaprion brevirostris. | prey preference of juvenile lemon sharks negaprion brevirostris was examined in experiments conducted in field-based pens where the fish were offered meals of live teleosts: grey snapper lutjanus griseus and yellow fin majorra gerres cinereus in ratios of l. griseus:g. cinereus varying from 10:0 to 2:8. relative electivity indices for each treatment showed that n. brevirostris preyed on g. cinereus rather than l. griseus. they showed a prey preference relating to density of g. cinereus (type ii ... | 2009 | 20738496 |
