Testing Molecular and Otolith Tools to Investigate Population-of-Origin and Migration in Arctic Cisco Found in the Colville River, Alaska (AK-06-08)

The lowest harvest rates ever occurred in the critical subsistence resource, Colville River arctic cisco, raised urgent concerns about the possible effects of offshore oil and gas development in the early 2000s. A 2003 Arctic Cisco Workshop conducted in Nuiqsut with both scientific and local arctic cisco experts identified the highest priority information needs with regard to the Colville River arctic cisco subsistence population. Identification of the source populations of arctic cisco recruits and their movement along the North Slope is a question of considerable importance to the native people in this area, and their subsistence harvest. The recent declines in the number and size of fish in the subsistence harvest have made this question a high priority for MMS in our responsibility to manage offshore development of oil and gas in the Beaufort Sea Planning area. This study will help determine the level of vulnerability of the Colville River arctic cisco by establishing the level of genetic and geographic isolation of the spawning stock. The study will also test the ability of recent innovations in otolith (fish ‘earbone’) microchemistry technology to answer the above question.
