Subject: FN0759-Salmon - Fraser River Sockeye and Pink Update - Areas 11 to 29 - August 1, 2017
The Fraser River Panel met on Tuesday, August 1 to receive an update on the
migration of the Fraser sockeye and pink runs to date and review the status of
migration conditions in the Fraser River watershed.
Gill net test fishing catches remain very poor in Area 12 but have fluctuated
considerably in Area 20 in recent days while purse seine test catches have been
improving in Area 12 and declining in Area 20. The Area 13 purse seine test
fishery began on July 31 with a modest catch in the first day of operation. The
combination of the gill net and purse seine test catches in the two approach
areas has resulted in an increase in the projected diversion rate through
Johnstone Strait to 38% which remains below the pre-season forecast of 51%.
In-river gill net test catches have been mixed with Whonnock having extremely
low catches since testing began in early July and Cottonwood having increased
catches in recent days.
Stock identification information is currently indicating that Early Stuart
sockeye have cleared the marine and lower Fraser River test fishing areas. The
most recent DNA samples taken in the marine purse seine test fisheries show
sockeye stock compositions in Area 20 of approximately 0% Early Stuart, 13%
Early Summer, 85% Summer and 2% Late run stocks. In Area 12, the purse seine
stock composition was 0% Early Stuart, 21% Early Summer, 78% Summer and 1% Late
run stocks. In-river stock identification information remains highly uncertain
as sample sizes have been extremely low.
Daily Mission hydroacoustics escapement estimates have increased in recent days
with the largest daily escapement estimate to date being 12,400 on July 31. The
total estimated sockeye escapement as of July 31 is 119,300. Hell’s Gate
observations continue to be extremely low in recent days.
During the call today, the Fraser Panel made no changes to the Early Stuart or
Early Summer run sizes of 50,000 and 166,000 respectively. The estimated
escapement past Mission of Early Stuart, Early Summer and Summer run sockeye as
of July 31 is 44,600, 39,500 and 35,200 fish respectively.
At the current run size for Early Summer run sockeye there is no TAC available
and as such no sockeye directed fisheries are being considered at this time. In
addition Summer run stocks continue to track well below the p25 forecast level,
however, it is too early to make any run size modifications at this time.
On July 31, the Fraser River water discharge at Hope was 3,045 m3/s, which is
approximately 30% lower than average for this date. The water temperature of
the Fraser River at Qualark Creek on July 31 increased to 18.7°C which is 0.7°C
higher than average for this date. The forecast is for water temperatures to
increase to 19.9°C by August 6. Due to the very low discharge levels, water
temperatures are highly influenced by air temperatures.
For pre-season planning purposes the Fraser Panel had adopted management
adjustments (MA) for Early Summer, Summer and Late run sockeye that reflect the
forecast water temperature and discharge conditions based on the May and June
information for Early Summer and Summer run sockeye, and anticipated river
entry dates for Late run fish. Due to the very poor return of Early Summer run
stocks they are now being managed based on a Low Abundance Exploitation Rate
(LAER) limit and as such there will be no modifications to the in-season MA for
this group. Management adjustments are additional fish that are set aside from
identified harvest levels and allowed to migrate upstream in an attempt to
assist in achievement of identified spawner objectives for the different run
timing groups. In-season information in the coming weeks will help to inform
future decisions on management adjustments for the Summer management group
while the Early Stuart, Early Summer and Late run management groups will be
managed based on the respective LAER for each group (10% for Early Stuart and
Early Summers and 20% for Lates). There will be no in-season estimates of
management adjustment for Early Stuart, Early Summer and Late run groups in
2017.
At this time it is too early to assess the return of Fraser pink salmon. Recent
test fishery catches in the marine approach areas have shown increasing
abundances of pink salmon. The first stock ID samples analyzed for Areas 12 and
20 purse seine test fisheries indicate Fraser origin pink salmon comprise 24
and 16 percent respectively. Run size and timing updates for Fraser pinks will
likely begin in mid to late August.
First Nations food, social and ceremonial (FSC) sockeye fisheries have been
restricted by a 4 week window closure protecting Early Stuart and the earliest
timed Early Summer run stocks with limited fishing opportunities to date
directed at chinook salmon. Due to the apparent later than average run timing
and/or weakness in the returns of Early Summer and Summer run stocks, the start-
up of sockeye directed FSC fisheries will continue to be delayed until there is
an identification of TAC for Early Summer and/or Summer run sockeye.
FSC fishers in marine approach areas as well as the Fraser River are requested
to check for the opening times and any restrictions in their local area.
Given the low returns to date there are no fisheries directed upon Fraser River
sockeye scheduled at this time, and updates will continue to be provided
following meetings of the Fraser River Panel on Tuesdays and Fridays of each
week.
The next in-season meeting of the Fraser River Panel is scheduled to occur on
Friday, August 4, 2017.
