Fish life history, diets, and habitat use in the Northwest Territories : freshwater sculpin species / by T. Arciszewski ... [et al.]. : Fs97-4/3066E-PDF

"The Family Cottidae consists of over 300 species across 70 genera that are found in both marine and fresh waters. Although most sculpin species are marine, there are three freshwater sculpin species reported in the Northwest Territories (NWT): Slimy Sculpin (Cottus cognatus, Richardson 1836), Spoonhead Sculpin (C. ricei, Nelson 1876), and Deepwater Sculpin (Myoxocephalus thompsonii, Girard 1851). This report reviews the literature for life history, diet, and habitat requirements of these three species. Scientific and anecdotal information from other sculpin species is also included where relevant. Not surprisingly there is an extreme paucity of information on sculpins in the north when compared to other areas (e.g., the Laurentian Great Lakes basin), and therefore this report relies heavily on life history information gathered about these species from areas other than Arctic and sub-Arctic regions. Clearly there is a strong need for research to better understand how these three sculpin species may be affected by current and future developments, and to determine how well the information from southern areas relates to the NWT"--Introd., p. 1.
