This dataset contains temperature data taken from 11 streams or rivers in Forillon National Park since 2008. Temperature data are collected hourly by a HOBO probe installed on the watercourse’s bottom in June and removed in September or October. For each watercourse studied, the temperature probe is installed at the benthic invertebrate community sampling site (CABIN) close to the site at which the electrofishing is carried out. Temperature data are particularly useful for assessing the quality of brook trout aquatic ecosystems in Forillon National Park.
This dataset covers the monitoring of benthic invertebrate communities in 11 streams or rivers in Forillon National Park since 2007. The sampling methods and techniques used for this monitoring are based on those of the Canadian Aquatic Biomonitoring Network (CABIN) established by Environment Canada. This follow-up is usually done in early fall. The collection site is located near the brook trout community and water temperature monitoring site for each of the watercourses studied.
This dataset covers the status of the commercial lobster (Homarus americanus) fishery. Commercial lobster fishing activities within the administrative boundaries of Forillon National Park inevitably have impacts on this invertebrate population. Through annual stock status monitoring, it is possible to study the impacts of the fishery and changes in the lobster population in the coastal waters of the park. Data are gathered by means of at-sea sampling, whereby a monitoring team boards lobster vessels to collect data at sea during three periods of the fishing season.
This dataset concerns monitoring of the Penouille eelgrass beds. Because of the ecological importance not only of eelgrass beds, but also of the animal communities they support, eelgrass beds are often used as indicators of coastal ecosystem health. Two sets of data deal more specifically with animal species, mainly fish, which use this habitat for different stages of their life cycle. They contain data related to each of the three sites sampled in the spring and fall using fyke nets since 2013.
Water temperature is considered a key ecosystem driver in freshwater ponds and streams of PEI National Park. American eel and Eastern Brook trout have been chosen for evaluating pond and stream temperature conditions as they are a common residents in most Atlantic Canada water bodies. Eastern brook trout are intolerant of warm water conditions. Stream temperature and brook trout growth are important factors that can directly influence survival, growth and distribution.
Stream temperature increases due to climate change, land clearing, beaver activity, etc... can be stressful for resident fishes and other aquatic species. Bruce Peninsula National Park monitors three creeks for thermal stress; particular emphasis is on Brook Trout habitat suitability.
Fisheries Information Summary System (FISS) layer of Historic (pre 2001) Fish Distribution Points of BC Streams. Points represent site locations where a fish species is rearing, spawning or observed or where a point is located at the mouth of a stream it indicates the presence of a fish species somewhere in the stream as a whole. Georeferenced to the stream centreline network layer of the 1:50,000 scale BC Watershed Atlas.
Stream thermal regime has important consequences for aquatic organisms, and is sensitive to climate and land use. The Park is monitoring thermal regimes at 10 sites annually from spring to fall using temperature loggers. The water temperature is recorded hourly and these data used to assess the suitability of the thermal environment of streams for Brook Trout.
The effects of climate warming, eutrophication, air pollutant inputs and forestry activity that occurred before La Mauricie National Park was created influenced and continue to influence today water quality in the park. These stress factors threaten the natural evolution of aquatic ecosystems. On several small lakes, the quality of the habitat has not ensured the maintenance of the eastern brook trout population and has decreased the beaver population. In order to monitor the aquatic ecosystems, sampling of a number of predetermined lakes is being carried out and water quality is being measured by evaluating parameters related to acidification, eutrophication, general water quality, and oxygen and temperature conditions.
This is a backpack electrofishing based survey that enumerates all species caught a random selection of sites within a given watershed. Cascade, Panther and Spray watersheds were sampled in the fall of 2015, 2016 and 2017 respectively. The purpose is to repeat these surveys every 10 years to quantify changes to the distribution of native and non-native fishes.
