Presentation Transcript

  1. Robert Emmett, Marisa Litz, Andrew Claiborne, and Paul Bentley NOAA Fisheries, Northwest Fisheries Science Center Oceanographic Conditions and Sardine off Oregon/Washington

  2. 2007 2006 June Sea Surface Temperature Anomalies 2008 2010 2011 2009

  3. Average monthly surface temperatures (3 m depth) off the Columbia River 1998-2011.

  4. Catches of sardines in 2011 in surface trawl during daytime tows and surface temperature.

  5. Length frequency of Pacific sardine (Sardinops sagax) captured off Oregon/Washington in May, June, and Sept 2011 during BPA plume study.

  6. Length-frequency of Pacific sardine captured during September 2006 – 2011 off the Oregon/Washington coast during the BPA plume study. Only 3 caught in September 2010

  7. Length frequency of Pacific sardine captured off the Columbia River August 2010

  8. 2011

  9. Columbia River estuary sardine length frequencies

  10. Primary findings in 2011 • The ocean was relatively cold in spring/early summer 2011 – La Nina and cold PDO • Ocean conditions appeared poor for successful spawning /recruitment off OR/WA in 2011 – No 0-age sardines were observed in September 2011. • We were unable to estimate the sardine population abundance off the Columbia River because of reduced night time surface trawling sampling efforts. • Most sardines caught in 2011 were large/older individuals –2009 year-class is around but nearshore.

  11. Sardine tagging in 2011 Pacific Ocean Shelf Tracking Project (POST) V7, operating at 180kHz 365 day life
