| levels of 226ra, 210pb and total u in fish near a saskatchewan uranium mine and mill. | radionuclide levels in fish from the beaverlodge lake area, saskatchewan, canada, varied significantly among lakes, species and tissues, but did not vary with fish sex or age. fish from lakes affected by an operating uranium mine and mill had radionuclide levels one to two orders of magnitude above levels in fish from an uncontaminated control lake. concentrations were greatest in white suckers, intermediate in lake whitefish, and low in lake trout. skin and bone contained the highest radionucli ... | 1983 | 6688247 |
| chemical contaminants and parasites: assessment of human health risks associated with consumption of whitefish (coregonus clupeaformis) from two boreal lakes in northern saskatchewan, canada. | in canada there is increasing concern about potential effects of industrial activities on wildlife and human health. in an interdisciplinary study concentrations of inorganic (metals, metalloids) and organic (pcbs, organochlorine pesticides) contaminants, and parasitic infections of lake whitefish (coregonus clupeaformis) from montreal and reindeer lakes, saskatchewan, were investigated to assess human health risk related to fish consumption. in both lakes contamination of fish with chemical sub ... | 2012 | 22440886 |
| a toxicological examination of whitefish (coregonus clupeaformis) and northern pike (esox lucius) exposed to uranium mine tailings. | operation of the gunnar uranium mine, in nothern saskatchewan, canada, from 1955 to 1964, resulted in the deposition of radioactive tailings in langley bay, a small bay connected to lake athabasca. previous publications have described the contamination of the sediments, water, macrophytes and fish of this area. the present study compares the parasite infestations, blood hematocrit, histopathology and condition factor (k) of the langley bay whitefish and northern pike populations with these facto ... | 2013 | 2386411 |
| flavobacterium columnare: an important contributing factor to fish die-offs in southern lakes of saskatchewan, canada. | during june and july 2012, buffalo pound lake and blackstrap lake in saskatchewan, canada were visited biweekly and surveyed for sick and dying fish. during this investigation, 2 fish kills were identified. buffalo pound experienced a large die-off of yellow perch (perca flavascens) in june, while blackstrap experienced a die-off of lake whitefish (coregonus clupeaformis) in july. in excess of 50 fish were examined for gross lesions at each lake, and dead and moribund fish consistently had 1 or ... | 2014 | 25274742 |
