Residence Description

• Residence description for Coastrange Sculpin (Cottus aleuticus), Cultus population in Canada (2022)
  It is generally assumed that female Coastrange Sculpin (Cottus aleuticus) lay egg masses under stones that are then guarded by males (National Recovery Team for Cultus Pygmy Sculpin 2007).
• Residence description for the Bull Trout (Salvelinus confluentus) (Saskatchewan-Nelson rivers populations) in Canada (2022)
  A spawning nest, or “redd” is considered to be the residence for Bull Trout (Salvelinus confluentus). Similar to all salmonids that spawn within rivers, Bull Trout construct redds in locations that contain gravel substrates and exhibit groundwater upwelling.
• Residence description for the Misty Lake Sticklebacks (Gasterosteus aculeatus) in Canada (2022)
  Due to the dark colour of the lake and streams, it is difficult to know exactly where the Misty Lake Sticklebacks (Gasterosteus aculeatus) build their nests. Breeding activity occurs in the lake and streams of the Misty Lake system; however gravid females of both the inlet stream and lake populations were collected in the inlet swampy transition zone (McPhail 1994).
• Residence description for the Nooksack Dace (Rhinichthys cataractae ssp.) in Canada (2022)
  Nooksack Dace (Rhinichthys cataractae ssp.) spawn at night during the spring and usually at the upstream end of riffles (McPhail 1997). They establish small breeding territories (a 10 cm diameter nest) in coarse substrate (Bartnik 1972).
• Residence description for the Rainbow Trout (Oncorhynchus mykiss) Athabasca River populations in Canada (2022)
  Redds are created by female Athabasca Rainbow Trout (Oncorhynchus mykiss) for spawning and the initial development of eggs and alevins. Athabasca Rainbow Trout redds meet the SARA definition of residence.
• Residence description for the Rocky Mountain Sculpin (Cottus sp.), Eastslope populations, in Canada (2022)
  Rocky Mountain Sculpin (Cottus sp.; Eastslope populations) are largely sedentary and relatively uniform in distribution in Alberta streams where they exist, so nests can likely occur at any location in a stream channel where appropriate structure exists.
• Residence description for the Western Brook Lamprey – Morrison Creek Population (Lampetra richardsoni) in Canada (2022)
  Morrison Creek Lamprey (Lampetra richardsoni) are known to have one type of residence: a nest. Both sexes of Morrison Creek Lamprey participate in building a nest before spawning, though males do much of the work (Beamish et al. 1999; COSEWIC 2010).
• Residence description for the Westslope Cutthroat Trout (Oncorhynchus clarkii lewisi), Alberta Populations in Canada (2022)
  Westslope Cutthroat Trout (Oncorhynchus clarkii lewisi) are known to have one type of residence: a redd. In Alberta, Westslope Cutthroat Trout generally spawn in small gravel-bottomed streams where the female prepares a redd in the gravel by thrashing her tail to displace gravel until a depression about 30 cm wide and 12 cm deep is dug.
• Description of Residence for Paxton Lake and Vananda Creek Stickleback Species Pairs in Canada (2019)
  Paxton Lake and Vananda Creek Benthic and Limnetic Sticklebacks build nests within the littoral zone of the lakes in which they are found. These nests are considered residences as defined by the Species at Risk Act SARA.
• Description of Residence for Vancouver Lamprey (Lampetra macrostoma) in Canada (2019)
  Vancouver Lamprey construct nests in or near tributary deltas of streams flowing into either Cowichan or Mesachie lakes, or in Cowichan, Bear, or Mesachie lakes themselves.
• Description of Residence for Bank Swallow (Riparia riparia) in Canada (2019)
  The following is a description of residence for Bank Swallow (Riparia riparia), created for the purpose of implementing section 33 of the Species at Risk Act (SARA) which relates to the damage or destruction of residences. Such damage or destruction can result from any alteration to the topography, structure, geology, soil conditions, vegetation, chemical composition of air/water, surface or groundwater hydrology, micro-climate, or sound environm ...
• Description of Residence for Barn Swallow (Hirundo rustica) in Canada (2019)
  The following is a description of residence for Barn Swallow (Hirundo rustica), created for the purpose of implementing section 33 of the Species at Risk Act (SARA) which relates to the damage or destruction of residences. Such damage or destruction can result from any alteration to the topography, structure, geology, soil conditions, vegetation, chemical composition of air/water, surface or groundwater hydrology, micro-climate, or sound environm ...
• Residence statement for the Atlantic Salmon (Salmo salar), inner Bay of Fundy population (2018)
  A spawning redd is a residence for Atlantic Salmon, inner Bay of Fundy population (iBoF Salmon). The redd has the structural form and function of a nest and is used for salmon egg incubation, hatching, and the early rearing of hatchlings (alevins). One redd can contain hundreds to several thousands of eggs from a single female salmon. The female salmon constructs the redd during spawning and invests energy in its creation. A redd is typically occ ...
• Residence Description for the Atlantic Mud-piddock (Barnea truncata) in Canada (2018)
  The Atlantic Mud-piddock’s burrow is its residence. Once a Mud-piddock larva settles on its preferred red mudstone substrate, it invests energy in creating a burrow that is essential to its survival. The Mud-piddock grows and matures in its burrow. It feeds and releases spawn from within its burrows where it remains for the duration of its adult life stage.
• Description of Residence for the Western Chorus Frog – Great Lakes, St. Lawrence- Canadian Shield Population (Pseudacris triseriata) in Canada (2016)
  The following is a description of residence for the Western Chorus Frog, Great Lakes, St. Lawrence – Canadian Shield population (Pseudacris triseriata, hereafter Western Chorus Frog), created for the purpose of implementing section 33 of the Species at Risk Act (SARA) which relates to the damage or destruction of residences. Such damage or destruction can result from any alteration to the topography, geology, soil conditions, vegetation, chemica ...
