Range and Identity
Cottus cognatus has a broad northern distribution, including much of Canada and Alaska, selected United States drainages and Siberian records. The range spans distinct regional populations. A historical locality should retain its date and identification rather than being treated as proof of present occupancy.
Habitat and Behavior
Adults use rocky riffles in cold streams, rocky lake habitat, springs and spring outflows. Some lake records come from substantial depth, while spawning movements can bring fish into shallower water. Stream and lake observations therefore describe complementary parts of the species’ habitat.
Food and Life History
The upper reference is 12.1 centimeters total length. Food is mainly aquatic insect larvae and nymphs, with crustaceans, small fishes and some plant material also recorded. Males select cover beneath a rock or ledge and guard deposited eggs.
Field Note
Include the nesting cover and life stage when observing reproduction. An occupied space beneath a rock may contain eggs and a guarding male, so it should remain undisturbed.
