Found 10 records similar to Fish thermal stress - Terra Nova

Federal

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.

Since 2009, up to nine (9) streams (White River, Willow River, Oiseau Creek, White Gravel River, North Swallow River, Swallow River, Cascade River, Tagouche Creek and Imogene Creek) are monitored with stream temperature HOBO loggers to assess thermal suitability for Brook trout (Salvelinus fontinalis). In 2016 and 2017, a second logger was deployed at each of the streams. Loggers are deployed in each stream during the summer, between Lake Superior and the first barrier. Data from the two loggers are analyzed separately for each week and the lower maximum weekly trimean temperature from each stream is used.

Terra Nova National Park uses fixed station stream gauges and pressure temperature loggers to monitor the following stream flow aspects: Richards-Baker index of flashiness, ratio of yearly precipitation to runoff, low flow volume, annual maxima/minima, and mean monthly flow.

Stream hydrology strongly affects habitat quality for most stream-dwelling species, and is affected by both climate and land use. This measure, which is colocated with stream temperature regime, reports on flow parameters in 10-12 park streams over time - using in-situ water level data loggers, as well as hydrometric stations.

Hydrology is a key factor affecting biodiversity and the ecological functioning of aquatic and riparian ecosystems through sediment transport, erosion, water chemistry, etc. Automated data loggers are being used to record year-round hourly measurments of absolute in-stream pressure, absolute barometric pressure and water level in headwater streams of the Ivitak focal watershed, in Torngat Mountains national park. Note that because the data loggers being used (Hobo U20) also records hourly water temperature readings this measure is co-located with a stream temperature measure.

Water temperature is a critical variable in stream ecology, and in particular has direct implications for fish populations. Automated data loggers are being used to record year-round hourly measurments of water temperature in various watersheds in Torngat Mountains national park. Note that because the data loggers being used (Hobo U20) also records hourly water level readings this measure is co-located with a stream hydrology measure.

What? Stream temperatures on third order streams in Cape Breton Highlands National Park are being monitored to determine if mean water temperatures are changing over time. When? Monitoring frequency occurs annually from June 15th to September 15th on various park streams.

Terra Nova National Park employs a kicknet sampling procedure to monitor the species richness and relative species abundance of stream invertebrates. Streams chosen for sampling are randomly selected within second order watersheds.

The influence of water temperature on the ecology of aquatic organisms with optimal thermal ranges is quite substantial, as these regimes regulate activity, growth, survival, and spawning behaviour. In consequence, a deviation from normal temperature ranges often cause displacement, disease, or even mortality therefore water temperature constitutes an important limiting factor for the condition of fish habitat and freshwater ecosystems. The purpose of the fish thermal stress monitoring program at Kouchibouguac National Park is to determine the number of consecutive “hot” days within a particular time period and detect changes in the level of thermal stress imposed on fish due to warm temperatures. Atlantic salmon (Salmo salar) was selected as a focus species due to its lowest thermal tolerance compared to several other fish groups.
