| [fatty acid profile of mero (epinephelus morio) raw and processed oil captured in the yucatan peninsula, mexico]. | unsaturated fatty acids are of current interest for their potential to reduce cardiovascular disease, the first cause of death worldwide. by its content of essential fatty acids, fish is one of the food products most in demand among the population. one of the most popular processes for fish consumption in yucatan peninsula, mexico is frying. however, studies show that frying food causes changes in the composition generating trans fatty acids. the objective of this study was to evaluate the fatty ... | 2014 | 25617583 |
| temporal and spatial mapping of red grouper epinephelus morio sound production. | the goals of this project were to determine the daily, seasonal and spatial patterns of red grouper epinephelus morio sound production on the west florida shelf (wfs) using passive acoustics. an 11 month time series of acoustic data from fixed recorders deployed at a known e. morio aggregation site showed that e. morio produce sounds throughout the day and during all months of the year. increased calling (number of files containing e. morio sound) was correlated to sunrise and sunset, and peaked ... | 2014 | 25141790 |
| modeling coral reef fish home range movements in dry tortugas, florida. | underestimation of reef fish space use may result in marine reserves that are too small to effectively buffer a portion of the stock from fishing mortality. commonly used statistical home range models, such as minimum convex polygon (mcp) or 95% kernel density (95% kd) methods, require the exclusion of individuals who move beyond the bounds of the tracking study. spatially explicit individual-based models of fish home range movements parameterized from multiple years of acoustic tracking data we ... | 2014 | 24558320 |
| spatial and temporal repeatability in parasite community structure of tropical fish hosts. | an assessment is made of the repeatability of parasite community structure in space for a marine fish, and in space and time for a freshwater fish from south-eastern mexico. the marine fish species was the red grouper, epinephelus morio (collected from 9 localities), and the freshwater species was the cichlid, cichlasoma urophthalmus (collected from 6 localities: including monthly at 2 localities for 1 year, and bimonthly at 1 locality in 1990 and 1999). pairwise interspecific associations and a ... | 2003 | 14636025 |
| effects of preservation methods of muscle tissue from upper-trophic level reef fishes on stable isotope values (δ (13)c and δ (15)n). | research that uses stable isotope analysis often involves a delay between sample collection in the field and laboratory processing, therefore requiring preservation to prevent or reduce tissue degradation and associated isotopic compositions. although there is a growing literature describing the effects of various preservation techniques, the results are often contextual, unpredictable and vary among taxa, suggesting the need to treat each species individually. we conducted a controlled experime ... | 2015 | 25834776 |

| '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 |
| first description of the male and redescription of the female of philometra salgadoi vidal-martínez et al., 1995 (nematoda: philometridae) from the ocular cavity of the marine fish epinephelus morio in mexico. | a redescription of the female and the first description of the male of the philometrid nematode philomnetra salgadoi vidal-martínez, aguirre-macedo et moravec, 1995 are presented on the basis of specimens collected from the type host, the red grouper. epinephelus morio (valenciennes; pisces: serranidae), in the gulf of mexico off the northern coast of yucatan, mexico. the morphology of this species is compared with that of related congeneric species. | 2001 | 11484847 |
| pearsonellum lemusi n. sp.
