Increased productivity from sewage effluents can enhance species richness locally. Results from a study of Spottail shiners (Notropis hudsonius) in 1999 showed that prevalence and the mean number of myxozoan parasite species per host were higher downstream of the wastewater outflow from the...

Dataset contains laboratory-studied Fathead minnow (Pimephales promelas) survival when exposed to bitumen sediments from the oil sands region of northern Alberta, cut through the McMurray Formation (MF). These are the results of the toxicological exposures, when Fathead minnow embryos were...

Wild fish community data (species, abundance, diversity, length, weight) for 2013 and 2019 are now available for tributaries of the Athabasca River (rivers Steepbank, Ells, Firebag, High Hills, Dunkirk, Horse, Muskeg, Tar and Calumet) and 2017 data for rivers and creeks adjacent to Christina Lake...

Wild fish health data (length, weight, gonad size, etc.) are now available for trout perch collected from the Athabasca and Peace Rivers; white sucker collected from the Athabasca River; longnose sucker collected from the Peace River; slimy sculpin collected from the Steepbank River; lake chub...

The Canadian Environmental Sustainability Indicators program provides data and information to track Canada's performance on key environmental sustainability issues. The Polybrominated diphenyl ethers in fish and sediment indicators identify the drainage regions where concentrations are below or...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Perfluorooctane sulfonate in fish and water indicators provide information on the presence of perfluorooctane sulfonate...

Parasite communities were examined in Johnny Darters (Etheostoma nigrum) collected from five localities in the St. Lawrence River in southwestern Quebec: two reference localities, one polluted locality upstream of the Island of Montreal and downstream of industrial and agricultural activity, and...

Annual fish monitoring data for 20 lakes across Canada. Collection season was standardized to provide temporal comparability within each lake. In most lakes, fishing occurred in the fall. Predator fish were limited to trout, pike or walleye, to facilitate spatial comparisons. Ten to twenty top...

Environmental quality data from water, fish and sediments in 20 lakes across Canada. Measurements include mercury, methylmercury, physical-chemical parameters such as pH and alkalinity, stable isotopes, fish biological data, nutrients, ions, and metals. The data collection includes sites with a...
