Subject: FN0447-Salmon - Fraser River Spring 5-2 and Summer 5-2 Chinook - June 3rd Abundance Update
In 2013, the Department has identified concerns associated with expected poor
returns of Spring 5-2 and Summer 5-2 chinook to the Fraser River. Management
of these stocks is based on an in-season assessment of returns using the
cumulative catch per unit effort (CPUE) of chinook caught at the Albion Test
Fishery. A three zone management approach is used to identify management
actions.
The Department is planning to begin the season with management actions based on
the lowest management zone (zone 1) based on the number of spawners in the 2008
parental generation (32,000 chinook) and the recent lower than average survival
rates.
The model used to predict the returns of Spring 5-2 and Summer 5-2 chinook to
the Fraser River uses data from the standard chinook net at the Albion Test
fishery and does not use catch from the multi-panel net (which is currently
fished on alternating days). The standard chinook net is an 8 inch (approx.
20 cm) mesh.
The 2013 Albion chinook test fishery began operating on April 21st. A total of
two (2) chinook have been caught in the standard chinook net; no additional
chinook have been caught in the multi-panel net. This is the lowest catch
observed for this time period since the inception of the Albion chinook test
fishery in 1981. The CPUE input into the model falls below the range of
historical observations of CPUE (1995 to 2012, excluding 2007) used to develop
the Albion prediction model. Based on this CPUE, for the period May 5 to June
1, the current predicted return of Spring 5-2 and Summer 5-2 chinook to the
mouth of the Fraser ranges from 21,000 to 45,000 chinook (median of 31,000). A
need for a cautious approach to management of Fraser chinook continues to apply.
Management actions will be confirmed pending the final in-season update planned
for June 17th. Previously announced fishery management actions to conserve
Fraser River chinook remain in effect.
