Subject: FN0613-Salmon: Fraser River Sockeye Update - August 6 - Areas 11 to 29

The Fraser River Panel met today to review stock assessment data on the Fraser
River sockeye runs, plan fisheries, and discuss sockeye migration conditions in
the Fraser River watershed.

Test fishing catches over the past week indicate that the migration of Fraser
sockeye through both the northern and southern approach routes to the Fraser
River is increasing. DNA analyses indicate that the stock composition of Fraser
sockeye in the marine approach areas is presently about 30% Early Summer-run,
32% Summer-run, and 38% Late-run sockeye. The diversion rate of Fraser sockeye
through Johnstone Strait is currently estimated to be approximately 28%. There
has been a strong migration of sockeye observed at Hells Gate over the past
several days. The estimated total commercial catch of Fraser sockeye to-date is
75,000 fish, while non-commercial catches (from test, First Nations FSC,
Charter, and recreational fisheries) total 189,000 fish.

The Scotch/Seymour stock component of the Early Summer-run sockeye timing group
is continuing to show strength in marine area DNA samples. At the meeting
today, the provisional run size estimate of 950,000 Early Summer-run sockeye
was increased to an estimate of 1,600,000 fish. The 50% marine migration timing
of Early Summer-run sockeye through Area 20 is estimated to be August 2. The
estimated escapement of Early Summer-run sockeye past Mission through August 5
is 641,000 fish. Summer-run sockeye abundance assessments are ongoing. An
estimate of the Summer-run run size should be available next week after the
expected peak migration through Area 20 has occurred. The estimated escapement
of Summer-run sockeye past Mission through August 5 is 380,000 fish. DNA
analyses of sockeye samples from Juan de Fuca and Johnstone Straits indicate
that Late Shuswap sockeye are the most abundant Late-run stock in the marine
approach areas, which is consistent with the pre-season forecast. A run size
assessment for Late-run sockeye should be available by about mid August unless
their peak marine migration timing is later than expected. Late-run sockeye
migratory behavior in terminal areas will be assessed over the next several
weeks in order to estimate the proportion of the run delaying in the Strait of
Georgia prior to entering the Fraser River. It is too early to provide an
assessment of the run size of Late-run sockeye, however, if they are near their
forecast level of abundance they will comprise most of the Fraser sockeye
migrating through the marine assessment areas in the coming weeks. At the
meeting today, the provisional run size estimate of 400,000 Harrison sockeye
was unchanged. The estimated escapement of Late-run sockeye past Mission
through August 5 is 332,000 fish.

On August 5 the discharge of the Fraser River at Hope was about 3,200 cms,
which is 22% below average for this date. The temperature of the Fraser River
at Qualark Creek on August 5 was 19.0 0C, which is 1.4 0C above average for
this date. Fraser River water temperatures at Qualark Creek are forecast to
increase to approximately 20 0C over the next few days and then decrease to
18.8 0C by August 13. Water temperatures between approximately 19 0C and 20 0C
can adversely affect the upstream migration of Fraser sockeye and may cause en
route mortality of some of these fish. At the meeting today, after reviewing
environmental and stock assessment information, the Panel approved an increase
in the management adjustment factor for Early Summer-run sockeye from 0.62 to
0.84. Management adjustments are employed to help achieve spawning escapement
targets for Fraser River sockeye.

The following fisheries are planned:

The Area B seine fishery will open daily 0600 hrs to 2100 hrs Sunday, August 8
through Thursday, August 12 in portions of Management Area 12, 13 and 20.
Please see separate Fishery Notice for further details on this opening.

The current Licence Area D gillnet opening will be extended from 1500 hrs
Friday, August 6 to 1200 hrs Saturday, August 7 in portions of Management Areas
11, 12 and 13. Please see separate Fishery Notice for further details on this

The Area H troll fishery will open Sunday, August 8 at 0001 hrs until further
notice in portions of Management Areas 12, 13, 18 and 29. Please see separate
Fishery Notice for further details on this opening.

The Area E gillnet fishery will open Tuesday, August 10 from 1400 hrs to 1700
hrs in portions of Area 29 with 100 fathom net length restriction. Please see
separate Fishery Notice for further details on this opening.

Fraser River recreational fishing will open for sockeye retention upstream of
Mission bridge to Alexandra Bridge and in the Harrison River downstream of the
Highway 7 bridge to the Fraser River confluence in Region 2 on Monday, August
9thuntil further notice. Please see separate Fishery Notice for further details
on this opening.

First Nation fisheries vary by areas with opportunities in marine areas, lower
Fraser and portions of the BC interior area; consult with local DFO offices for
openings. Window closure restrictions are still in effect in portions of the BC
Interior area at this time. Refer to the 2010 Southern B.C. Salmon IFMP for
details on the timing dates for these closures.

The next Fraser River Panel meeting is scheduled for Monday, August 9th. A
further update will be provided on this date.
