Aspects of the Life History of the Pond Smelt (Hypomesus olidus) in the Yukon and Northwest Territories
The pond smelt (Hypomesus olidus) has a limited North American distribution, being restricted to the west coast of Alaska and the drainage of the lower Mackenzie River, N.W.T. This study examined an isolated population in a small tundra lake on the Yukon coastal plain. Otolith interpretation reveale...
