| health of flatfish from localities in placentia bay, newfoundland, contaminated with petroleum and pcbs. | this study compared the health of flatfish inhabiting two areas in placentia bay, newfoundland, contaminated either with polycyclic aromatic hydrocarbons (pahs) or polychlorinated biphenyls (pcbs) with samples from reference sites. initially, four species of flatfish, including american plaice (hippoglossoides platessoides), yellowtail flounder (limanda ferruginea), gray sole (glyptocephalus cynoglossus), and winter flounder (pleuronectes americanus), were sampled only for external lesions from ... | 2003 | 12712279 |
| influence of a thermal discharge on parasites of a cold-water flatfish, pleuronectes americanus, as a bioindicator of subtle environmental change. | a study was conducted to ascertain the influence of a thermal discharge on the health and parasites of a coastal cold-water flatfish, the winter flounder (pleuronectes americanus), a species sensitive to environmental change. flounder were sampled in spring 1998 and 1999 beneath the plume and at reference sites north and south up to 1 km from the discharge. species diversity and estimates of abundance of macroscopic algae, invertebrates, and fish were also recorded. after capture by scuba divers ... | 2007 | 18163365 |
| parasites of winter flounder (pleuronectes americanus) as an additional bioindicator of stress-related exposure to untreated pulp and paper mill effluent: a 5-year field study. | a study was conducted in a marine inlet to assess the effects of untreated discharges from a pulp and paper mill, a municipality, and industries in western newfoundland on winter flounder (pleuronectes americanus), a fish species shown previously to be sensitive to environmental contaminants in sediment. the fish were captured by scuba divers about 2 km down-current from the mill discharging effluent containing resin acids, and at three reference sites 2 to 11 km away near the opposite shore, ea ... | 2007 | 17160488 |
| assessment of stress-related bioindicators in winter flounder (pleuronectes americanus) exposed to discharges from a pulp and paper mill in newfoundland: a 5-year field study. | this study assessed the effects of discharges from a sulphite-bleaching paper mill on winter flounder (pleuronectes americanus) sampled each spring over a 5-year period in st. george's bay, newfoundland, prior to foraging activity. the fish were captured by scuba divers near the mill and at a reference site 10 km up current. several bioindicators were used to assess fish health. larger and older flounder exhibiting gross and microscopic tissue lesions, lower condition factor, and elevated hepato ... | 2006 | 16485169 |
