A fisheries and water quality survey of ten lakes in the Richardson Tower area, Northeastern Alberta. Vol I: Methodology, summary, and discussionDownload
A fisheries and water quality survey was conducted in September 1979 on 10 small lakes (67.4 to 338.9 ha) in the vicinity of Richardson Tower, approximately 140 km north of Fort McMurray, Alberta. The major objectives were: (1) to determine morphometric and water quality characteristics in...

A fisheries and water quality survey was conducted in September 1979 on 10 small lakes (67.4 to 338.9 hal in the vicinity of Richardson Tower, approximately 140 km north of Fort McMurray, Alberta). The major objectives were: (1) to determine morphometric and water quality characteristics in...
A laboratory study of long-term effects of mine depressurization groundwater on fish and invertebratesDownload
This study was conducted to determine long-term toxic effects, on selected species of fish and invertebrates, of mine depressurization at concentrations non-lethal in acute toxicity tests. The study also includes chronic toxicity experiments, studies of sublethal effects of groundwater, and a...
Mathematical models have been widely applied to perform chemical risk assessments on biological populations for a variety of ecotoxicological pro- cesses. In this paper, by introducing a dose-dependent mortality rate function, we formulate a toxin-dependent aquatic population model that...
A socioeconomic evaluation of the recreational use of fish and wildlife resources in Alberta, with particular reference to the AOSERP study area. Volume I: Summary and conclusionsDownload
An estimated total of 1,390,980 Albertans over five years of age engaged in nonconsumptive recreational fish and wildlife activities in the Province during 1975-76, of whom 102,600 also engaged in hunting and of whom 308,500 also engaged in fishing activities during the same period. The annual...
Syncrude Canada Ltd., which has operated an oil sands extraction plant at Mildred Lake since 1978, has undertaken various environmental studies associated with the development since 1971. The purpose of the 1984 investigation, which involved a multi-disciplinary study team, was to characterize...
Analyses are given for up to 12 metals and 4 pesticides with PCBs, of aquatic environment from 15 study sites along or near the Athabasca River from Fort McMurray north to the confluence of the Peace and Slave Rivers. There were 560 fish (8 species), 15 water, 14 sediment and a few phyto-plankton...
A synopsis of the physical and biological limnology and fishery programs within the Alberta oil sands areaDownload
“A Synopsis of the Physical and Biological Limnology and Fishery Programs within the Alberta Oil Sands Area\" forms a background reference document on the limnology of the AOSER Program study area in northeastern Alberta. Within the report, the following items are discussed and summarized: data...
Vanadium concentrations of 2.4 to 5.6 mg/L were lethal in 7 days to rainbow trout of wet weight 1.2-6.2 g. The LC50 varied slightly over the 12 combinations of water quality, from hardness 30 to 350 units and pH 5.5 to 8.8. The 7-day LC5O may be estimated by the following equation, which...
The purpose of this study was to determine the acute and subacute toxicity of bitumen to rainbow trout. The bitumen was collected along the banks of the Athabasca River downstream of Fort McMurray during 1984. Prior to experimentation, the bitumen was fractionated in water at 35°C, using an...
