In the Kotzebue region of northwestern Alaska, Inconnu is one of the most important fishes harvested for subsistence purposes. With ongoing climate change, it is important to understand how a changing environment will affect Inconnu habitat use. This study described the habitat use of Inconnu in the Hotham Inlet/Selawik Lake complex from 2010 to 2012. Data collection consisted of surgically implanting acoustic telemetry tags in 80 fish from both rivers in 2010 and 2011 (n = 320), and deploying a fixed array of 20 Vemco VR2W acoustic receiving stations affixed with archival tags throughout the study area. Inconnu were detected at water temperatures and salinities ranging from −1.39 to 23.51°C and 0 to 31.3psu, respectively, and there was no detection of stock-specific or temporal trends in habitat use. Fish occupied colder water temperatures (−0.5 to 0.5°C) during winter and primarily occupied the upper (15°C) and lower (0°C) ends of the temperature spectrum during summer. Although Inconnu occupied the entire range of salinities available during summer and winter months, they generally occupied waters of 5 to 20psu. By providing a more thorough account of Inconnu habitat use, our results contribute baseline data for future comparisons to evaluate effects from climate-induced changes to Inconnu sustainability.
