| hematology and condition factor of tui chub and fathead minnow parasitized by nematode from upper klamath lake, oregon, usa. | this study evaluated the hematological profile and condition factor (kn) of tui chub siphateles bicolor and fathead minnow pimephales promelas and their associations with larvae of contracaecum sp. infection of the heart. a total of 30 tui chub and 17 fathead minnow were collected from upper klamath lake, oregon, usa, measured, and weighed and blood was drawn for hematological analysis. nematode larvae parasitized tui chub with a prevalence of 50% and mean intensity of 1.40, while 11.8% of fathe ... | 2017 | 29160223 |
| responses of fathead minnows (pimephales promelas) during life-cycle exposures to pulp mill effluents at four long-term receiving water study sites. | we exposed fathead minnows (pimephales promelas to 7 concentrations of effluents from pulp mills at 4 long-term receiving water study (ltrws) sites. the primary objective of these investigations was to determine the potential for toxicity, particularly on fish reproduction, of the pulp mill effluents using laboratory tests. these tests were performed as ltrws fish community assessments were being completed, thus results of the laboratory fish reproduction tests could be compared to in-stream fis ... | 2009 | 19146231 |
| a long-term, multitrophic level study to assess pulp and paper mill effluent effects on aquatic communities in four us receiving waters: characteristics of the study streams, sample sites, mills, and mill effluents. | watershed characteristics, study streams, sample sites, mills, and mill effluents are provided for 4 streams included in a long-term study to assess potential effects of pulp and paper mill effluents on us receiving waters. the study streams are codorus creek (pennsylvania, usa), leaf river (mississippi, usa) and mckenzie and willamette rivers (oregon, usa) and were chosen to represent a blend of mill process types, effluent concentrations, and coldwater/warmwater stream systems. the described e ... | 2009 | 19063588 |
