  2. 2006 Fishery Summary • Pre-season forecast and plan/retrospective • Weekly fishery summary • Sockeye • Chinook • Escapements

  3. SOCKEYE Pre-season Forecast and Plan/Retrospective • Forecast 570,000 (represented an average of the two best performing forecast methods) • Actual forecast point estimates ranged from ~ 330K to 815K • Large esc in 2001 and 2002, but 2001 esc skewed to GCL with Sproat esc of 158K only slightly above the average for the stock. • Return of earlier age classes from the contributing brood years lower than expected (i.e. return 32’s and 42’s from the 2001 brood in 2004 and 2005 and 32’s from the 2002 brood in 2004).

  4. Somass Sockeye Pre-season Management Objectives: • avoid ‘front-end’ loading of catch • Manage by weekly harvest targets, • Commercial: First anticipated opening was June 28 (gillnet) • Sport: 4/day to end of June, reassess • First Nation: no explicit plans without agreement, goal, manage to weekly catch targets Intent: • To reduce risk later in the season (risk from factors such as a potential downgrade or environmental conditions that may lead to increased harvest rate due increased catchability and/or fish mortality … not meeting escapement target)

  8. 2006 Chinook Forecast • The 2006 return is a result of the 2001-2003 brood years. • Marine survival rates estimated to be almost 8% for 2001 and declined to less than 2% for the 2002 and 2003 brood years. • 25% 3 year olds from 2003’s 99,000 return • 28% 4 year olds from 2002’s 83,000 return • 46% 5 year olds from 2001’s 45,000 return • Expected return of females: 50%
