Subject: FN0838-Salmon - Fraser River Sockeye and Pink Update - Areas 11 to 29 - September 4, 2013

As a result of significant increases in Fraser pink sun size during the past
two weeks, pink directed fishing opportunities with non-retention of sockeye
are being planned in several areas. The Department is planning any fishery
openings with a cautious approach to minimize additional impacts on Fraser
River sockeye. The Department's priorities are to ensure that there is
sufficient sockeye returning to the spawning grounds and all fisheries are
being managed to minimize sockeye impacts Fishers are requested to check for
any restrictions in their local areas.

An update from the September 3, 2013 Fraser River Panel meeting follows:

The Fraser River Panel met on September 3, 2013 to review assessment data on
Fraser River sockeye and pink salmon, to discuss fisheries management plans for
the harvest of pink salmon, and to review environmental conditions in the
Fraser River watershed. Water temperatures within the Fraser River have
remained above average for this time of year in recent days. However,
temperatures have declined from the approximately 21.5 degrees Celsius peak
experienced during the peak summer run migration period. The passage of Fraser
sockeye through the marine assessment areas has been variable in recent days.
The most recent 5 day average diversion rate of Fraser sockeye through
Johnstone Strait has increased to 99% as of September 2, 2013. DNA analysis of
samples collected from recent test fisheries in Johnstone Strait and Juan de
Fuca Strait continue to be dominated by Summer-run sockeye followed closely by
Late run sockeye. The daily migration of sockeye past the Mission hydro
acoustic site has been in the range of 41,500 to 75,300 sockeye per day for the
last five days bringing the total estimated escapement to 3,133,900 as of
September 2, 2013. Pink salmon have also begun to enter the Fraser River with
daily migrations in the last few days in the 95,000 to 384,000 pink per day
range.

On September 3, 2013, there was no change to the Summer run size nor the 50%
run timing date. The low return of Summer-run sockeye has severely constrained
harvest opportunities that were expected during pre-season planning. Based on
pre-season information, Summer-run sockeye (Chilko, Quesnel, Late Stuart,
Stellako, Harrison, Raft, and North Thompson) were expected to provide most of
the fishing opportunities directed at Fraser sockeye this season. The estimated
escapement of Summer-run sockeye past Mission through September 2, 2013 is
2,026,200 fish.

At the Fraser Panel meeting today the panel adopted a run size change for late
run sockeye from the current 500,000 to a run size estimate of 600,000, with a
50% Area 20 run timing date of August 17, 2013. DNA analysis from marine test
fisheries indicates that Late Shuswap sockeye continue to make up the majority
of the Late run sockeye currently migrating through the marine approach areas.
The escapement of Late run sockeye past Mission as of September 2, 2013 is
estimated to be 414,700 fish.

Catches of pink salmon in marine test fisheries have continued to be at very
high levels in recent days. Recent DNA samples indicate that the proportion of
Fraser pink salmon have increased to 69-77% of the stock composition in
approach areas. The other pink stocks are non-Fraser South Coast Canadian
stocks and stocks destined for Washington State river systems. The diversion
rate of Fraser River pink salmon through Johnstone Strait has increased
significantly to 91% over last last 5 days. At the Fraser Panel meeting
yesterday the Fraser Panel adopted a run size increase from 16 million to 24
million for Fraser Pink salmon with an estimated 50% migration timing through
Area 20 of August 29, 2013.

On September 2, 2013, the Fraser River water discharge at Hope was 2,245 cms,
which is approximately 16% lower than average for this date. The temperature of
the Fraser River at Qualark Creek on September 2nd was 18.7 C, which is 2.4 C
higher than average. The Fraser Panel manages fisheries to provide additional
Fraser sockeye above the spawning escapement targets through application of
management adjustments. The management adjustments help ensure that the
escapement targets are achieved by off-setting en-route mortality and other
factors that could affect meeting spawning escapement targets. At the meeting
today the management adjustment factors remained unchanged at 2.48 for the
aggregate Summer run component and 0.90 for the Late run component.

At the meeting today the Panel approved extending ongoing US pink fisheries,
most of which are operating with non-retention sockeye restrictions in place.
For further information on US fisheries please see News and Announcements at
www.psc.org.

In Canada, the Area B seine fishery is scheduled to continue in portions of
Area 29. The commercial Area B Seine fishery is also scheduled to open in
portions of Area 12 on Wednesday September 4, 2013 until further notice. These
seine fisheries will be managed as Individual Transferable Quota (ITQ)
fisheries and will be based on available commercial total allowable catch (TAC)
for pink salmon. Sockeye impacts will also be managed using an ITQ of total
allowable mortalities to account for sockeye release mortality. As there is no
available commercial sockeye TAC, mandatory sockeye non-retention will be in
effect and any sockeye encountered must be released with the least possible
harm. Survival rates of sockeye released in this fishery are expected to be
high. Area 13 will remain closed at this time but it is anticipated to open
for both commercial seine and troll directed pink fishing later this week.

The next in-season meeting of the Panel is scheduled to occur on Friday,
September 6th, 2013.
