anaerobic bacteria associated with epizootics in grey mullet (mugil cephalus) and redfish (sciaenops ocellata) along the texas gulf coast. | anaerobic bacteria tentatively identified as species of catenabacterium were recovered from brain, liver, kidney and blood of fish involved in a massive epizootic of grey mullet (mugil cephalus) and redfish (sciaenops ocellata). pathogenicity was demonstrated for grey mullet (m. cephalus) and sea catfish (arius felis) but not for channel catfish (ictalurus punctatus) or white mice. diseased fish were disoriented, weak and swimming at the surface of the water. thioglycolate and salt bovine blood ... | 1976 | 16498893 |
environmental contaminants and biomarker responses in fish from the rio grande and its u.s. tributaries: spatial and temporal trends. | we collected, examined, and analyzed 368 fish of seven species from 10 sites on rivers of the rio grande basin (rgb) during late 1997 and early 1998 to document temporal and geographic trends in the concentrations of accumulative contaminants and to assess contaminant effects on the fish. sites were located on the mainstem of the rio grande and on the arroyo colorado and pecos river in texas (tx), new mexico (nm), and colorado. common carp (cyprinus carpio) and largemouth bass (micropterus salmo ... | 2005 | 16227080 |
mercury concentrations in fish from lake meredith, texas: implications for the issuance of fish consumption advisories. | we examined how length of fish is related to mercury concentrations in muscle tissue of seven species of fish from lake meredith, texas and determined how sex and growth rate are related to mercury concentration in walleye (sander vitreus). flathead catfish (pylodictis olivaris), walleye and white bass (morone chrysops) had the highest concentrations of mercury and channel catfish (ictalurus punctatus), common carp (cyprinus carpio), river carpsucker (carpiodes carpio) and gizzard shad (dorosoma ... | 2006 | 17054010 |
concentrations of polychlorinated biphenyls (pcbs) in water, sediment, and aquatic biota in the houston ship channel, texas. | polychlorinated biphenyls (pcbs) were quantified in water, sediment, and catfish and crab tissue collected from the houston ship channel (hsc) in texas. the total concentrations of the 209 pcb congeners ranged from 0.49 to 12.49 ng l(-1), 4.18 to 4601 ng g(-1) dry wt, 4.13 to 1596 ng g(-1) wet wt, and 3.44 to 169 ng g(-1) wet wt, in water, sediment, catfish and crab tissue, respectively. all media showed maximum concentrations greater than studies in other regions with the highest concentrations ... | 2008 | 17850847 |
bioaccumulation of polychlorinated dibenzodioxins and dibenzofurans in catfish and crabs along an estuarine salinity and contamination gradient. | elevated but variable levels of polychlorinated dibenzodioxins and polychlorinated dibenzofurans (pcdd/fs) were observed in hardhead sea catfish (hh) and blue crabs (bcs), as well as in water and sediment, of the houston ship channel system, texas, usa. it is hypothesized that the variation was caused by the spatial variability of pcdd/f contamination, together with the natural mobility of organisms in satisfying prey, temperature, salinity, and reproductive requirements. structural equation mod ... | 2009 | 19606914 |
perfluorinated compounds, polychlorinated biphenyls, and organochlorine pesticide contamination in composite food samples from dallas, texas, usa. | the objective of this article is to extend our previous studies of persistent organic pollutant (pop) contamination of u.s. food by measuring perfluorinated compounds (pfcs), organochlorine pesticides, and polychlorinated biphenyls (pcbs) in composite food samples. this study is part of a larger study reported in two articles, the other of which reports levels of polybrominated diphenyl ethers and hexabromocyclododecane brominated flame retardants in these composite foods [schecter et al. 2010. ... | 2010 | 20146964 |
snp discovery in wild and domesticated populations of blue catfish, ictalurus furcatus, using genotyping-by-sequencing and subsequent snp validation. | blue catfish, ictalurus furcatus, are valued in the united states as a trophy fishery for their capacity to reach large sizes, sometimes exceeding 45 kg. additionally, blue catfish × channel catfish (i. punctatus) hybrid food fish production has recently increased the demand for blue catfish broodstock. however, there has been little study of the genetic impacts and interaction of farmed, introduced and stocked populations of blue catfish. we utilized genotyping-by-sequencing (gbs) to capture an ... | 2014 | 24797164 |
predicted and observed therapeutic dose exceedances of ionizable pharmaceuticals in fish plasma from urban coastal systems. | instream flows of the rapidly urbanizing watersheds and estuaries of the gulf of mexico in texas (usa) are increasingly dominated by reclaimed waters. though ionizable pharmaceuticals have received increasing attention in freshwaters, many research questions remain unanswered, particularly in tidally influenced urban coastal systems, which experience significant spatiotemporal variability in ph that influences bioavailability and bioaccumulation. the authors coupled fish plasma modeling of thera ... | 2016 | 27003720 |
