From 1999-2006, approximately 80,000 Atka mackerel have been tagged and released in the Aleutian Islands, Alaska, specifically at Seguam Pass, Tanaga Pass, Amchitka Island and Kiska Island. To date, over 2,600 have been recovered. Tag releases were conducted aboard the chartered fishing vessel, Pacific Explorer, and tag recoveries were conducted aboard the chartered fishing vessel, Seafisher. In addition, the Atka mackerel fishery provided a substantial amount of the tag recoveries in the areas open to fishing. Tagging procedures and recovery sampling are described in detail in McDermott et al 2005.
The goal of this project is to use tagging methods to estimate local abundance and small scale movement of Atka mackerel around Steller sea lion rookeries and to examine potential fishery effects on Atka mackerel movement and abundance.
