Each year, rotary screw traps (smolt wheels) are installed in the Kedgwick River, Upsalquitch River and main Restigouche channel from early/mid May to mid/late June. All traps are checked daily, and all fish species are counted. The majority of Atlantic salmon smolts are measured and a fraction are weighted. Everyday, Atlantic salmon smolts are tagged with unique streamer tags and released upstream of the trap they were caught in with the hope that a fraction of them will be recaptured so the trap efficiency and abundance can be estimated (capture-mark-recapture experiment).

Results from temperature preference experiments demonstrated that individual personality was consistent and repeatability. Individual preferred and maximum avoidance temperatures were significantly reduced in hypoxia compared to normoxia. Standard metabolic rate increased with temperature and body mass. Patterns of projected habitat change suggest the spatial extent of the current distribution of Carmine shiner would shift north with global warming.

This service provides a compilation of Electronic Navigational Charts (ENC) produced by the Canadian Hydrographic Service. All information provided by this service conforms to the International Hydrographic Organization (IHO) Publication S-57. An ENC contains all the chart information useful for navigation, and may contain supplementary information in addition to that contained in the paper chart. This service is not for navigation.

Moored instrument time series data include current velocity, temperature, salinity, oxygen, fluorescence, transmissivity, turbidity, and particle capture of carbon, nitrogen, and silicon. Also included are sediment trap, ice drift and ice draft data. These data were collected by researchers from the Institute of Ocean Sciences, Sidney, BC, from locations ranging from the Beaufort Sea, and across the Canadian Arctic Archipelago to Baffin Bay. The data links below are only a representative sample of the entire collection.

This dataset is a contribution to the development of a kelp distribution vector dataset. Bull kelp (Nereocystis leutkeana) and giant kelp (Macrocystis pyrifera) are important canopy-forming kelp species found in marine nearshore habitats on the West coast of Canada. Often referred to as a foundation species, beds of kelp form structural underwater forests that offer habitat for fishes and invertebrates. Despite its far-ranging importance, kelp has experienced a decline in the west coast of North America.

The objectives of the fish component of the integrated oil sands monitoring program are to provide the necessary data/information to address key questions related to both environmental health of fish populations and fish health issues that can be used to inform human use and consumption.

The questions underlying the fish monitoring design are related to the status and health of wild fish populations in the Lower Athabasca River including and in an expanded geographical extent. Data is being collected to provide a baseline against which future changes in fish populations will be evaluated, and compared to data from historical studies to assess change over time to the current state. Data is also being collected in areas of new oil sands development, to develop baseline data for future site-specific comparisons, contribute to an expanded geographic basis of the overall monitoring plan, and contribute to an improved ability to examine cumulative effects.

Data on fish contaminants is collected across Ontario. Contaminants are chemicals that could be harmful to environment and human health. Toxic contaminants can enter in waterbodies in different ways and can accumulate in fish. Contaminants include: * mercury * polychlorinated biphenyls (PCBs) * dioxins/furans * organochlorine pesticides and others.

This dataset contains a list of Notification of Contamination (NOC) submissions and the most recent annual update information (if applicable). Regulated companies are required to report contamination to the CER through the online submission of a NOC when Contamination is identified or encountered during any phase of the Facility’s lifecycle, and the presence of Contamination is confirmed through analytical sampling, or when Contamination resulting from an Incident cannot be remediated within 12 weeks of the Incident being reported to the CER.
