Subject: FN0672-Salmon: Fraser River Sockeye Update - August 17 - 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 data collected over the past several
days indicates continued strong migration of Fraser sockeye through the marine
approach routes. DNA analyses indicate that the stock composition of Fraser
sockeye in the Areas 12 and 20 marine approach routes to the Fraser River are
ranging about 12-17% Early Summer-run, 18-32% Summer-run, and 56-64% Late-run
sockeye. The diversion rate of Fraser sockeye through Johnstone Strait is
currently estimated to be approximately 74%. The migration of sockeye past
Mission and Hells Gate has also been strong over the past several days. The
estimated total catch of Fraser sockeye to-date is 1,669,000 fish. Total
escapement past Mission is 3,167,000 for a total accounted to date of 4,836,000
fish.

The marine migration of Early Summer-run sockeye is dropping off in the latest
samples; the current run size estimate of 2,400,000 Early Summer-run sockeye
was increased to 2,600,000 fish. The 50% marine migration timing of Early
Summer-run sockeye through Area 20 is estimated to be August 4. The estimated
escapement of Early Summer-run sockeye past Mission through August 16 is
1,400,000 fish.

The marine migration of Summer-run sockeye has increased in recent days. At the
meeting today, the Panel approved a run size increase from 3,000,000 Summer-run
sockeye to 3,300,000. The 50% marine migration timing of Summer-run sockeye
through Area 20 is August 10. The estimated escapement of Summer-run sockeye
past Mission through August 16 is 1,139,000 fish.

Late-run sockeye are increasing in proportion of the sockeye migrating through
the marine approach areas and there are early indications that a portion of
them are delaying in the lower Strait of Georgia prior to entering the Fraser
River. The gulf troll test fishery started Monday to conduct assessments of the
abundance of Late-run sockeye that are delaying their migration. A total
abundance assessment for Late-run sockeye should be available later this coming
week. At the meeting today run size estimate of 700,000 Harrison sockeye was
unchanged with 50% marine timing through Area 20 of August 4. The estimated
escapement of Late-run sockeye past Mission through August 16 is 931,000 fish.

On August 16 the discharge of the Fraser River at Hope was 2,740 cms, which is
21% below average for this date. The temperature of the Fraser River at Qualark
Creek on August 16 was 18.8 0C, which is 1.2 0C above average for this date.
Fraser River water temperatures at Qualark Creek are forecast to increase only
slightly over the next few days then decrease. At the meeting today, after
reviewing environmental and stock assessment information, the Panel changed the
management adjustment factor for Early Summer-run sockeye from 0.8 to 0.71 and
for Summer-run sockeye a management adjustment factor was changed from 0.24 to
0.22. Management adjustments are employed to help achieve spawning escapement
targets for Fraser River sockeye.

The following fisheries are planned/on-going:

The Area B Seine fishery remains open with new vessel quota levels in portions
of Area 12, 13 and 20 from 06:00 hrs to 21:00 hrs daily until Friday August 20,
2010. Also, Seines will open in a portion of Area 29 from 06:00 hrs to 21:00
hrs on Wednesday, August 18 for a limited assessment fishery. Please refer to
the specific Fishery notices for further details.

The Area H Troll fishery remains open until further notice in portions of
Management Areas 12, 13, 18 and 29 with new vessel quota levels. Please refer
to the specific Fishery Notice for further details.

The Area D Gill Net fishery is extended from Tuesday August 17 at 14:00 hrs to
Thursday August 19 at 18:00hrs in portions of Areas 11, 12 and 13. Please refer
to the specific Fishery Notice for further details.

The Area E Gill Net fishery will open Wednesday August 18 for 5 hours from
10:00 hrs to 15:00 hrs in portions of Area 29. Please refer to the specific
Fishery notice for more details.

Recreational fishing is open for sockeye retention in south coast marine areas
and in the Fraser River. Please refer to the specific Fishery Notices for
further details.

First Nation fisheries vary by areas with opportunities in marine and Fraser
River area; consult with local DFO offices for openings.

The next Fraser River Panel meeting is scheduled for Friday, August 20th. A
further update will be provided on this date.
