Individually numbered loop spaghetti tags released during research cruises; all recoveries from fishing industry. Main release groups in February 2003 at two locations: 1) N of Cape Sarichef, Unimak Island, and 2) off Amak Island, north of the Alaska peninsula. Other smaller releases at several locations in southeat Bering Sea from April 2002 to November 2003. Pacific cod (Gadus macrocephalus) caught with commercial and research pot gear from depths of 50-150 meters; length of tagged fish primarily 50-80 cm. Data in MS Access format (digital tabular). Data include lat/long of capture and release locations, release date/time, fish length and condition at release. Recovery data includes location and date of recovery, recovering vessel and gear, fishery observer, recipient for tag reward. Most recovery locations in lat/lon to nearest minute, some to state or federal stat area only; variables code quality of recovery location and date info. Most records include length, weight, sex, and condition of recovered fish, some otoliths collected. Recoveries primarily documented by fishery observers on vessel or at delivery plant. Database includes tags recovered through Dec 2007. Total of 6871 tags released, 2634 tags recovered. Important caveats: 1) tags released opportunistically, not in design or associated with quantitative model, 2) most tage releases were in main commercial fishing ground during fishing season, assumptions of mixing with overall population are invalid, 3) all recoveries through industry, spatial and temporal distribution of recovery effort very non-uniform, some areas little or no effort. Raw data including coordinates of tag recoveries and vessel information are considered observer data and are confidential under the Magnuson-Stevens Act. Pilot/feasibility study for spaghetti tagging of Pacific cod in Alaskan waters. Qualitative evaluation of cod movement patterns near large spawning ground. Local movement of cod in area of localized depletion study off Cape Sarichef, Unimak Island. Most of the releases were performed from cruises funded by NMFS (Steller Sea Lion Research), and recovery information processing and rewards were also funded by NMFS (staff salaries). Data analysis was funded by NPRB. completed McDermott, Susanne susanne.mcdermott@noaa.gov pointOfContact Felthoven, Ron 206-526-4114 7600 Sand Point Way NE Seattle WA 98115-6349 USA ron.felthoven@noaa.gov custodian notPlanned tagging theme Alaska continental shelf Amak Island Bering Sea Pribilof Islands Unimak Island Unimak Pass southeast Bering Sea western Gulf of Alaska place DOC/NOAA/NMFS/AFSC > Alaska Fisheries Science Center, National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

Recovery location generally lat/long to degrees/minutes at end of commercial tow. Some records location to state or federal stat area only; some lat/longs estimated as centroid of stat area. Tags recovered in deliveries to processing plants may have estimated dates over range of vessel trip (usually 3-days). All recovery data reviewed for data entry accuracy and recovery locations checked. Variables in database classify quality of recovery location and date data. Opportunistic release locations selected to qualitatively assess movement in area northeast of Unimak Pass, not uniform or desigend pattern over space/time. Lat/lon of release locations collected by research vessel navigation GPS/software. Size of fish tagged restricted by size selectivity of pot gear. Most fish tagged 50-80 cm fork length (3-5 yrs old). No juvenile fish tagged. Sex of tagged fish determined at recovery in most cases. Species id of tagged fish confirmed by AFSC scientists during tagging. Release length recorded to nearest cm. Accuracy of recovery data dependent on observer training/experience. Fish with obvious injuries or barotrauma culled before tagging. Some initial tag mortality studies, but no quantiative tag mortality rate estimates. No tag loss or tag recovery rate estimates. Completeness Report Tag number -999 indicate tags that were returned but where the tag was damaged and the serial number unreadable. For some tags the number was partially obscured, where tag number was partially inferrred from fish data is indicated in comment field. Missing values occur in all data fields except primary tag type and number. Conceptual Consistency All data subjected to QA/QC review. Release data files reviewed in Excel format after field cruise. Recovery data entry proofed for accuracy. GIS used to plot release and recovery locations for reasonableness (e.g., not on land) Database scanned for impossible values (recovery length less than release length, recovery date earlier than release date); anomalies flagged but not removed.
