Subject: FN0737-Salmon: Fraser River Sockeye Update - August 27 - Areas 11 to 29 - Update

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 Johnstone
Straits. DNA analyses indicate that the stock composition of Fraser sockeye in
the Areas 12 and 20 marine approach routes to the Fraser River are currently
less than 1% Early Summer-run, 5-6% Summer-run, and 93-94% Late-run sockeye.
The diversion rate of Fraser sockeye through Johnstone Strait is currently
estimated to be approximately 95%. The migration of sockeye past Mission and
Hells Gate continues to be strong over the past several days. The estimated
total catch of Fraser sockeye to-date is 5,700,000 fish. Total escapement past
Mission is 6,400,000 for a total accounted to date of 12,100,000 fish.
The marine migration of Early Summer-run sockeye is essentially complete; the
current run size estimate of 3,200,000 Early Summer-run sockeye was increased
to 3,700,000 fish. The 50% marine migration timing of Early Summer-run sockeye
through Area 20 is estimated to be August 9. The estimated escapement of Early
Summer-run sockeye past Mission through August 26 is 2,473,000 fish.

The marine migration of Summer-run sockeye has been decreasing in recent days.
At the meeting today, the Panel approved a run size increase from 4,500,000
Summer-run sockeye to 4,800,000. The 50% marine migration timing of Summer-run
sockeye through Area 20 is August 15. The estimated escapement of Summer-run
sockeye past Mission through August 26 is 2,471,000 fish.

Late-run sockeye are the dominant stock group in marine approach areas and in
addition there are large numbers of Late-run sockeye delaying in the lower
Strait of Georgia prior to entering the Fraser River. This migration pattern is
more consistent with historical migrations which we had not seen for a few
years. At the meeting today the Panel approved an increase to Shuswap/Weaver
Late-run sockeye from 16 million to 20 million with an August 24 timing date
through Area 20. At the meeting today run size estimate of 1 million Harrison
sockeye was increased to 1.2 million with a marine timing through Area 20 of
August 11th. The estimated escapement of Late-run sockeye past Mission through
August 26 is 1,839,000 fish. Birkenhead run size is unchanged at 241,000.

On August 26 the discharge of the Fraser River at Hope was 2,070 cms, which is
32% below average for this date. The temperature of the Fraser River at Qualark
Creek on August 26 was 17.8 0C, which is 1.0 0C above average for this date. At
the meeting today, after reviewing environmental and stock assessment
information, the Panel changed the management adjustment factor for Early
Summer-run sockeye from 0.38 to 0.36 and for Summer-run sockeye a management
adjustment factor from 0.15. Management adjustments are employed to help
achieve spawning escapement targets for Fraser River sockeye.


The following fisheries are planned/ongoing:

The Area B Seine fishery remains open until further notice with new vessel
quota levels in portions of Area 12 and 13 from 06:00 hours to 21:00 hours
daily. Area 20 will close on Friday, August 27th, Friday at 21:00 hours as
scheduled. Please refer to the specific Fishery notices for more 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 Notices for further details.

The Area D Gill Net fishery is currently open until 08:00 hours Sunday, August
29 at which time they will close. The Area D Gill Net fishery will re-open on

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
