The Fraser River Panel met today to review stock assessment data on the Fraser
River sockeye and pink salmon runs and to discuss fishery planning. Purse seine
test fishing catches of Fraser River sockeye in Johnstone Strait were strong
over the weekend. The diversion rate of Fraser sockeye through Johnstone Strait
continued to increase over the past week and is currently estimated to be
approximately 75%. Thus far this season, the diversion rate of Fraser sockeye
through Johnstone Strait has been higher and their marine migration timing
later than was expected during pre-season planning. DNA analyses indicate that
the stock composition of Fraser sockeye in the marine approach areas is
presently about 5% Early Summer-run, 40-50% Summer-run, and 50-55% Late-run
sockeye. The proportions of four-year-old Fraser sockeye migrating through the
marine assessment are approximately 50%, excluding the Harrison sockeye.
Abundance estimates of sockeye passage at Mission has been in the 40,000-65,000
range over the past few days and expected to increase to 100,000-150,000 per
day. The estimated escapement of Early Summer-run sockeye past Mission through
August 7 is 228,000. The estimated escapement of Summer-run sockeye past
Mission through August 7 is 185,000 fish. The estimated escapement of Late-run
sockeye past Mission through August 7 is 211,000 fish.
There were no run size changes at today's meeting.
DFO's forecast of the 50% marine timing of Fraser River pink salmon through
Area 20 is August 31. The forecast diversion rate of Fraser pinks through
Johnstone Strait this season is 59%. The marine timing and diversion rate
forecasting models for Fraser pink salmon have high uncertainty associated with
them. The forecast of later than expected marine timing of Fraser pinks and
higher than expected diversion rate is consistent with present sockeye
observations. The migration of pink salmon through Johnstone Strait has been
higher over recent days. DNA analyses of pink salmon samples collected in
Johnstone Strait and Juan de Fuca Strait test fisheries indicate that Fraser
pink salmon currently comprise only a low proportion of the samples. Their
contribution to marine area abundances of pink salmon is expected to increase
over the next few weeks as they near their expected peak marine migration
period near the end of the month. Fisheries targeting Fraser River pink salmon
will be constrained by conservation concerns for Late-run Fraser sockeye stocks.
On August 7, the Fraser River water discharge at Hope was approximately 5800
cms, which is about 42% higher than average for this date. The temperature of
the Fraser River at Qualark Creek on August 7 was 16.4C°, which is 1.4°C cooler
than average for this date. There were no changes to any management adjustments
at the meeting today. Management adjustments are additional fish that are
allowed to escape upstream to help achieve spawning escapement targets for
Fraser River sockeye.
The following fisheries are planned:
The First Nations food, social and ceremonial fisheries for sockeye are now
underway in all areas.
Licence Area E gill nets to open in portions of Management Areas 29, Thursday,
August 11 from 1PM to 3PM. Check with specific Fishery Notices for further
details.
Tsawwassen Harvest Agreement gill net fishery to open in portions of Management
Area 29 Wednesday, August 10 from 11AM to 3PM.
Marine recreational fishery retention of sockeye to start Wednesday, August
10th. Check with specific Fishery Notices for further details.
The next meeting of the Panel is scheduled to occur on Tuesday, August 9, 2011.
