| the prevalence of trypanosoma catostomi in white sucker (catostomus commersoni) from southern ontario. | during the summer of 1975, 285 white suckers (catostomus commersoni) from 10 localities in southern ontario were examined for trypanosomes. trypanosoma catostomi daly and degiusti, 1971 was found in the blood of 11.6% of the fish examined using the haematocrit centrifugation technique. infected juvenile fish (33%) and infected adult fish (4%) were found in 6 of 10 locations. | 1979 | 501849 |

| non-linear radionuclide transfer from the aquatic environment to fish. | uptake of 226ra, 232th, 230th, and 228th from water, sediment, and diet sources to bone and muscle of white suckers (catostomus commersoni) was studied in sixteen lakes in the uranium-mining district of ontario, canada. fish tissues did not increase linearly with environmental concentrations. the best relationship appears to be a power function. this has implications for the accuracy of radiological dose and risk estimates for uranium mining impacts, which are often based on a linear model. | 1997 | 9287090 |
| polybrominated diphenyl ethers (pbdes) in great lakes fish: levels, patterns, trends and implications for human exposure. | levels of polybrominated diphenyl ethers (pbdes) were measured in edible portions of great lakes fish, with the goal of examining patterns/trends and evaluating implications for human exposure. a total of 470 fillets of 18 fish species collected from various parts of the canadian waters of the great lakes between 2006 and 2013 were analyzed for 17 (expanded to 33 in 2009) pbdes. for a limited number of species, fillet to whole body and fillet to eggs pbdes were compared to examine pattern and co ... | 2017 | 27865120 |
| direct and indirect responses of a freshwater food web to a potent synthetic oestrogen. | endocrine-disrupting chemicals (edcs) in municipal effluents directly affect the sexual development and reproductive success of fishes, but indirect effects on invertebrate prey or fish predators through reduced predation or prey availability, respectively, are unknown. at the experimental lakes area in northwestern ontario, canada, a long-term, whole-lake experiment was conducted using a before-after-control-impact design to determine both direct and indirect effects of the synthetic oestrogen ... | 2014 | 25405967 |
| pathogenesis of skin and liver neoplasms in white suckers from industrially polluted areas in lake ontario. | increased prevalences of epidermal and hepatobiliary neoplasms in white suckers (catostomu commersoni) and brown bullheads (ictalurus nebulosus) in the western region of lake ontario have been associated with industrial pollution, but the identity and causative role of environmental carcinogens have not yet been established. most epidermal tumors of lip and body skin are benign focal proliferations that occur in fish from the polluted hamilton region, and also in fish from less polluted sites in ... | 1990 | 2360036 |
| linking mechanistic toxicology to population models in forecasting recovery from chemical stress: a case study from jackfish bay, ontario, canada. | recovery of fish and wildlife populations after stressor mitigation serves as a basis for evaluating remediation success. unfortunately, effectively monitoring population status on a routine basis can be difficult and costly. in the present study, the authors describe a framework that can be applied in conjunction with field monitoring efforts (e.g., through effects-based monitoring programs) to link chemically induced alterations in molecular and biochemical endpoints to adverse outcomes in who ... | 2015 | 25943079 |
