Subject: FN0700-Salmon: Fraser River Sockeye Update - August 20 - 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 7-8% Early Summer-run, 11-20% Summer-run, and 71-79% Late-run
sockeye. The diversion rate of Fraser sockeye through Johnstone Strait is
currently estimated to be approximately 75%. 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 2,634,000 fish. Total
escapement past Mission is 4,869,000 for a total accounted to date of 7,503,000
fish.

The marine migration of Early Summer-run sockeye continues to drop off in the
latest samples; the current run size estimate of 2,600,000 Early Summer-run
sockeye was increased to 2,900,000 fish. The 50% marine migration timing of
Early Summer-run sockeye through Area 20 is estimated to be August 7. The
estimated escapement of Early Summer-run sockeye past Mission through August 19
is 1,961,000 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 3,300,000 Summer-run
sockeye to 4,000,000. 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 19 is 1,823,000 fish.

Late-run sockeye are now the dominant stock group in marine approach areas and
there are indications of significant delaying in the lower Strait of Georgia
prior to entering the Fraser River. The gulf troll test fishery confirms
assessments of the abundance of Late-run sockeye that are delaying their
migration. A Late-run sockeye of 11 million Late Shuswap/Weaver stocks was
adopted at todays meeting. At the meeting today run size estimate of 700,000
Harrison sockeye was increased to 900,000 with a marine timing through Area 20
of August 6. The estimated escapement of Late-run sockeye past Mission through
August 169 is 1,417,000 fish.

On August 19 the discharge of the Fraser River at Hope was 2,540 cms, which is
25% below average for this date. The temperature of the Fraser River at Qualark
Creek on August 19 was 19 0C, which is 1.5 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 0.71 to 0.39 and for Summer-run sockeye a management
adjustment factor was unchanged at 0.22. Management adjustments are employed to
help achieve spawning escapement targets for Fraser River sockeye.


The following fisheries are planned:
