Distribution of Hyalella azteca in British Columbia in British Columbia


Hyalella azteca is found in continental North America, from Mexico north to the tree line in Canada and Alaska, from the Atlantic to the Pacific including coastal islands. It is the most common and widely distributed freshwater amphipod crustacean in North America (Bousfield, 1958). It is common and widespread in British Columbia. It is found in all permanent freshwater that reaches a monthly mean summer temperature of more than 10°C, in lakes, ponds, sloughs, marshes, estuaries, rivers, streams, ditches, and spring streams (Bousfield, 1958). It is sometimes found in alkaline and brackish waters (Pennak, 1989).
