Subject: FN0741-Salmon - Fraser River Sockeye and Pink Update - Areas 11 to 29 - July 28, 2017
The Fraser River Panel met on Friday, July 28 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 improved
substantially in Area 20 yesterday. Conversely, purse seine test fishing
catches improved substantially in Area 12 while Area 20 showed only modest
increases yesterday. In-river gill net test catches have continued to be very
poor since testing began in early July.
Stock identification information continues to show a decline in the proportion
of Early Stuart sockeye in all areas with Summer run stocks now dominating the
stock proportion in all marine areas. In-river stock identification information
is highly uncertain as sample size has been extremely low. The first
observation of late run stocks occurred in Area 20 on July 26.
Daily Mission hydroacoustics escapement estimates have continued to be very low
ranging from 1,300 to 4,500 over the past several days. The total estimated
sockeye escapement as of July 27 is 80,600. Hell's Gate observations continue
to be extremely low in recent days.
During today's Panel call, the start-up of the purse seine test fishery in Area
13 was confirmed for Monday, July 31. Based on the gill net and seine test
fishery catches in Areas 12 and 20, the diversion rate through Johnstone Strait
has increased to 32% which remains below the pre-season predicted rate of 51%
for the entire season.
The most recent DNA samples taken in the marine test fisheries show sockeye
stock compositions in Area 20 of approximately 2% Early Stuart, 30% Early
Summer, 67% Summer and 1% Late run stocks. In Area 12 the stock composition
was 0% Early Stuart, 22% Early Summer, 78% Summer and 0% Late run stocks.
During the call today, the Fraser Panel made no changes to the Early Stuart run
size of 50,000 with an Area 20 peak run timing of July 3. The estimated
escapement past Mission of Early Stuart sockeye as of July 27 is 43,900 fish.
Early Summer run stocks continue to track well below the p25 forecast of
166,000 with some of the later timed stocks in this group just beginning to
show in recent marine test fisheries samples. During the Panel call today the
decision was made to remain at the provisional run size for Early Summers of
166,000 (p25 forecast) that was adopted at Tuesdays meeting. It is anticipated
that a further reduction to the Early summer run size is likely to occur at
next Tuesdays meeting. At this run size there is no TAC available and as such
no sockeye directed fisheries are being considered at this time.
Summer run stocks are also tracking well below the p25 forecast level, however,
it is far too early to make any run size modifications at this time. The
estimated escapement of Early Summer-run and Summer-run sockeye past Mission
through July 27 is only 25,300 and 11,400 respectively. Both are well below the
expected levels for this date.
On July 27, the Fraser River water discharge at Hope was 3,280 m3/s, which is
approximately 29% lower than average for this date. The water temperature of
the Fraser River at Qualark Creek on July 27 increased to 18.6°C due largely to
warming air temperatures in recent days and is 0.7°C higher than average for
this date. The forecast is for water temperatures to increase to 19.9°C by
August 2. 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) approach 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.
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
Tuesday, August 1, 2017.
