2017 NASS RIVER SALMON STOCK ASSESSMENT UPDATE – MONDAY, 19 JUNE
The following is the first general public update for 2017 of Nass River salmon and summer‐run steelhead stock assessments from the Nisga’a Lisims Government Fisheries and Wildlife Department. All data presented in this update are preliminary and subject to change with further assessment information that becomes available and should be interpreted cautiously. For in‐season assessment purposes only. NASS RIVER ASSESSMENT OPERATIONS UPDATE OPERATIONAL ASSESSMENT INFORMATION FOR 2017
1. Fishwheel Assessment data: 31 May to 18 June (see below) 2. Meziadin Fishway data: Operation will begin on 1 July 3. Kwinageese Weir data: Operation will begin in mid‐July GITWINKSIHLKW (GW) FISHWHEELS (NASS TEST FISHERY –STARTED IN 1994 [24th year]):
The Nass River test fishery fishwheels began operation on 31 May for tagging and historical catch index assessments for salmon and summer‐run steelhead. All fish caught in the GW fishwheels to date were released alive after tagging and/or counting. Fishwheels 1 and 2 are currently operating at 0.9 m lower than average water levels (2.3 m vs. 3.2 m) based on 1994–2016 operations after operating at high water levels, peaking at just under 6 m (4000 m3/s). A chart of the water levels at the test fishery follows the text summary that compares current levels to historical levels. The Nass River water temperature is 0.2 °C above average (8.6°C vs. 8.4°C) based on the 1994–2016 operations. GREASE HARBOUR (GH) FISHWHEELS:
Start‐up dates of the GH fishwheels were 6 June (FW3 and FW6), 7 June (FW5), and 15 June (FW4). Four fishwheels are currently operating at Grease Harbour (upstream of Ts'im Anwiihlist). The GH fishwheels are used for in‐season mark‐recapture tag recoveries, abundance estimates passing upstream, additional tagging (adult Chinook and Chum salmon, and Pacific Lamprey), and for selective harvesting when permitted by NLG. Of the 133 Sockeye caught at all fishwheels to date, all have been released. The Nass fishwheel catches are currently below average for Sockeye and Chinook, about average for steelhead, and above average for Pacific Lamprey. Weekly comparisons of salmon and steelhead catches at the Gitwinksihlkw and all fishwheels to historical levels since 1994 follow the text summary as well as a catch summary of all fish species. Total fishwheel catches of salmon, steelhead, and Pacific Lamprey to date are shown below including tagging results and jacks caught.
Nisga’aFisheriesWeeklyUpdate–19June2017Page2
Other adult species and juvenile salmon catches at the fishwheels to date include: 17 Rainbow Trout, 6 Dolly Varden, 6 Whitefish sp., 4 Pike Minnow, 2 Cutthroat Trout, 1 Peamouth Chub, 1 Sucker, and 20 salmon smolts (10 Coho and 10 Chinook). RUN SIZE AND ESCAPEMENT ESTIMATES FOR NASS SALMON & SUMMER‐RUN STEELHEAD
In‐season estimates of run size and projected forecasts to Gitwinksihlkw fishwheels for adult Nass salmon and summer‐run steelhead are shown below and currently based on historical catch index methods. The current run sizes for 2017 are currently below average for Nass Sockeye and Chinook salmon when compared to means to date from 1994 to 2016. Summer‐run steelhead estimates begin on 1 July.
In‐season projected return forecasts to date are shown below. Estimates to GW are based on two methods, mean run timing and log‐regression of the in‐season to final estimates. The run size projections for Chinook and Sockeye are currently below target to reach the run size goal based on the mean run timing method with approximately 3.9% and 3.1% of runs entering the Nass River, respectively; but projections are early and the in‐season to final method indicates targets could be reached. The mean run‐timing projections are highly uncertain at this time with wide projected bounds for Chinook (13,000 – 25,000) and Sockeye (229,000 – 326,000).
Net Escapement Estimates for adult Nass salmon and summer‐run steelhead to date are shown below and relative to the Upper Nass escapement goals.

104 (Noyes/Dall) – not open yet. No catches of salmon in Alaskan net fisheries in Districts 101–104 have been reported to date for week ending 17 JUNE. The average total mean harvest of Nass Sockeye in Alaskan fisheries from 2000 to 2016 was 126,000 (range: 47,000‐300,000). CANADIAN COMMERCIAL NET FISHERIES IN AREA 3 (information courtesy from DFO Prince Rupert):
Area 3 commercial net fisheries started on 6 June 2017 for gillnets. Total net fisheries conducted in Area 3 to date are four gillnet fisheries. Next fisheries in Area 3 are 19 June and 20 June for gillnets. Commercial net harvest and release data to 18 June 2017 for salmon and steelhead in Area 3 are shown below:
LABELS: SO=SOCKEYE, PK=PINK, CO=COHO, CH=CHINOOK; STEEL=STEELHEAD, HARV=HARVESTED, AND REL=RELEASED; VESSELS=BOAT DAYS.
DFO plan to implement management actions in Area 3 to reduce harvest impacts on the Kwinageese Sockeye stock during their migration through Area 3 in mid‐July. The Sockeye stock requires rebuilding from a past spawning barrier detected in 2011 and poor returns from 2012 (<4,000 fish), 2013 (<400 fish), and 2014 (<500 fish). Sockeye retention will not be permitted in commercial fisheries in Area 3 from approximately 9‐22 July (WK 28 & 29), the anticipated peak of the Kwinageese Sockeye migration, as documented in DFO’s 2017 Integrated Fisheries Management Plan (IFMP). Sub‐area breakout of catch is as follows:
*Sub‐area catches reporting fewer than 5 boats are not shown by sub area but included in totals by gear type.
Of the total commercial catch (8,600) of Sockeye in Area 3, NFWD is estimating approximately 8,599 are of Nass origin (100%) based on stock composition modeling. The average total mean harvest of Nass Sockeye in Canadian commercial net fisheries from 2000 to 2016 is 211,000 (range: 25,000‐725,000). The table below shows hail data comparisons by week.

NISGA’A DOMESTIC (FSC) AND SALE FISHERIES:
Nisga’a domestic and sale fisheries are monitored by the Nisga’a Fisheries and Wildlife Department and began on 7 May 2017. Cumulative harvests to week ending 10 JUNE are shown in the table below for FSC catches. For the same week ending period, mean cumulative harvests from 2000 to 2016 are shown for comparison. The current total harvests estimated in 2017 are below average for all salmon and steelhead to date with exception of Pink.
Nisga’a Sale fishery information to date:
NFWD announced two 16 hour marine IS fishery openings for Friday, 23 June and Saturday, 24 June. The Nisga’a sale fisheries closure periods to allow the Kwinageese Sockeye stock to pass upriver are
planned for approximately: 9‐22 July for Marine and 13–26 July for In‐river sale fisheries. The total harvest summary of Nass salmon and steelhead to date in all of the Nisga’a harvest fisheries is as follows:
TOTAL RETURN TO CANADA (TRTC) AND NISGA’A ENTITLEMENT ESTIMATES FOR NASS SALMON
Pre‐season TRTC forecasts: Based on the preliminary Nass salmon return and age information from 2016, preliminary forecasts for Nass salmon and Nisga’a entitlement allocations for 2017 were calculated using pre‐season forecast models. Forecast models used were a combination of sibling (Sockeye and Chinook only) and 5‐year mean returns that project 25%, 50%, and 75% probability point estimates. Pre‐season TRTC forecasts (50% probability estimates) for 2017 predict a below average return forecast for Nass Sockeye (454,000 vs. 580,000), Nass Area odd‐year Pink (355,000 vs. 770,000), Nass Chinook (24,000 vs. 32,000), and Nass Chum (24,000 vs. 44,000), and above average return forecast for Nass Coho (276,000 vs. 210,000) based on mean TRTC estimates from 1994 to 2016.

Nisga’aFisheriesWeeklyUpdate–19June2017Page6
In‐season TRTC and Nisga’a entitlement estimates: Preliminary in‐season TRTC estimates estimated by NFWD for Nass Sockeye and Chinook are 424,000 (200,000–1,500,000) and 27,000 (10,000–55,000), respectively, based on harvest and run size data and mean run timing to date (Sockeye 3.1% and Chinook 3.9%) with standard deviation range estimates from 1994 to 2016 returns. The current in‐season TRTC estimates are currently tracking below the pre‐season forecasts for Sockeye and above for Nass Chinook salmon; but estimate ranges are large and uncertain until more of the returns enter the Nass River.
The next Nass River general stock assessment update from Nisga’a Fisheries is planned for: Monday, 26 June 2017. Nass stock assessment updates are available at the following links (no passwords are required): Weekly updates are posted after each Monday’s update to DFO and NLG’s websites:
