Found 10 records similar to Freshwater Inventory and Surveillance of Mercury: Fish Biological and Chemical Data

Federal

Annual freshwater quality monitoring data for 20 lakes across Canada. Parameters include total mercury, methylmercury, pH, alkalinity, specific conductance, colour, chlorophyll, nutrients, ions, dissolved inorganic and organic carbon, and total metals. In most years surface samples were collected from three locations on each lake, following nationally standardized protocols. Sampling occurred from 2008 to 2016, with six core lakes sampled throughout the eight-year period.

Sediment quality data for 20 lakes across Canada. Parameters include total mercury, methylmercury, sulfate, inorganic and organic carbon, nitrogen, and total recoverable metals. Bottom sediment samples were collected from one to three locations on each lake, following nationally standardized protocols. Sampling period was 2011 to 2016, with some core lakes sampled throughout the period and others sampled one time only.

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 period of record ranging from one year to eight years, starting in 2008. Fish analysed at each site include at least one top predator species and one prey species.

Effort, catch, and biometric fish data are produced using the Summer Profundal Index Netting (SPIN) methodologies developed by the Ontario Ministry of Natural Resources. Monitoring is generally conducted generally on a five year cycle, with additional sampling as necessary. Data are from Kingsmere Lake, where the majority of the park’s recreational lake trout fishing occurs. This monitoring allows the park to collect data on the size, structure and physical condition of the lake trout population.

Lakes and ponds are a significant aquatic feature in Waterton Lakes National Park. Due to the extreme topography, many of these water bodies were fishless prior to historic stocking. Historic stocking practices have highly altered fish
communities. In many locations the presence of nonnative fish is putting native fish populations in jeopardy.

Monitoring and surveillance data on the concentration of contaminants in selected species of fish and other aquatic biota collected to determine the environmental trends in contaminant levels and relationship to sources of pollution, the effectiveness of management actions, and the risk to fish and fish-consuming wildlife in the Great Lakes aquatic ecosystem are included in this dataset.

The contaminants in fish database is a compilation of contaminant data analysed from fish tissue at the Fresh Water Institute from 1970 to 2005. Data include lab number, region, analysis, organs, species, lake, form (whole fish, headon dressed, headless dressed), weight, and length and contaminant concentrations. Total mercury was the predominant contaminant measured. Results were expressed as ppm or ppb based on the parameter analyzed.
