1 218 NASS RIVER SALMON STOCK ASSESSMENT UPDATE MONDAY, 9 JULY The following is the fourth general public update for 218 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 Fishwheel Assessment data: 1 June to 8 July. Data summary below. 2. Meziadin Fishway data: Operations began on June 3. Counts to 8 July: 486 large Sockeye including 3 tagged fish (below average 2,925). 3. Kwinageese Weir data: Video weir operations began on 5 July. Count to 8 July: 3 large Chinook and 1 Bull Trout. GITWINKSIHLKW (GW) FISHWHEELS (NASS TEST FISHERY STARTED IN 1994 [25th year]): The Nass River test fishery fishwheels began operation on 1 June 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 1.1 m lower than average water levels (1.7 m vs. 2.8 m) based on operations after operating at record low water levels (up to 2.4 m lower than historical averages) from 1 17 June. 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.7 C above average (1.2 C vs. 9.5 C) based on the operations. GREASE HARBOUR (GH) FISHWHEELS: Start up dates of the GH fishwheels were on 5 June (FW5), 6 June (FW6), 7 June (FW3), and 15 June (FW4) for operating four fishwheels at Grease Harbour (upstream of Ts'im Anwiihlist). The GH fishwheels are used for inseason 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 Nisga a Lisims Government. Of the 4,355 Sockeye caught at all fishwheels to date, all have been released. The Nass fishwheel catches are currently below average for Sockeye, Chinook, and steelhead, and above average for pink, chum and Pacific Lamprey. Weekly comparisons of salmon and steelhead catches at the fishwheels to historical levels since 1994 follow the text summary as well as a catch summary of all fish species to date. Total fishwheel catches of salmon, steelhead, and Pacific Lamprey to date are shown below including tagging results and jacks caught.

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 are based on historical catch index and mark recapture methods. The current run sizes for 218 are currently below average for Nass Sockeye and Chinook salmon and just above average for summer run steelhead when compared to means to date from 1994 to 217. Summer run steelhead estimates began on 1 July and run size targets are based on minimum return goals as steelhead will enter the Nass River after the fishwheels shutdown in mid September.

Estimates to Gitwinksihlkw are based on two methods, mean run timing and log regression of the in season to final estimates to date. The current run size projection for Nass Sockeye is ranging between 17, and 35, to reach the run size goal (25,) based on the in season to final method with a point estimate of 26, based on 34% of the run entered to date based on mean run timing. The current run size projection for Nass Chinook is ranging between 8, and 15, to reach the run size goal (15,) based on in season to final method with a point estimate of 11, based on 79% of the run entered to date based on mean run timing. Of note, by 8 July, inseason run size forecasts for Nass Sockeye are performing well (mean absolute percent accuracy 82%; range=51 98% from 1994 to 217). For in season Chinook estimates to 8 July, mean percent accuracy is poorer (7%; range: 12 98% from 1999 to 217) than Sockeye but a reasonable indicator of abundance to date.

3 HARVEST ESTIMATES FOR ADULT NASS SALMON & STEELHEAD ALASKAN FISHERIES IN SE ALASKA (information courtesy from ADFG s website): Alaskan gillnet fisheries start dates in 218: District 11 (Tree Point) and District 16 (Sumner and Upper Clarence) opened on 17 June. Alaskan seine fisheries start dates in 218: District 11 (Lower Clarence/Revilla) on 1 July; District 12 (Middle Clarence) on 17 June; District 13 (Cordova) not open yet, and District 14 (Noyes/Dall) not open yet. The table below shows the current estimates of catches of salmon in Alaskan net fisheries in Districts (and mean catch comparisons from 2 to 217) to week ending 7 JULY 218 based on data from ADFG. Current salmon catches are below average for all species except for Chinook which is average. Of the total in season Sockeye catch reported in Alaskan fisheries to date (1,6), approximately 4, (4%) are estimated as Nass origin based on mean stock composition estimates from 1982 to 217 and are currently below average (24,) to date. The average total mean harvest of Nass Sockeye in Alaskan fisheries from 2 to 217 was 12, (range: 28, 3,). IN-SEASON SE ALASKAN CUM.

Total net fisheries conducted in Area 3 to date are four gillnet fisheries. Next commercial net fisheries announced in Area 3: 11 July (seine) with nonretention of Sockeye, Chinook, and steelhead.

The average total mean harvest of Nass Sockeye in Canadian commercial net fisheries in Areas 3 5 from 2 to 217 was 84, (range: 11, 28,). 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 Nass Sockeye stock requires rebuilding from a past spawning barrier detected in 211 that resulted in extreme poor returns in 213 (only 397 spawners) and 214 (only 498 spawners). Sockeye retention will not be permitted in commercial fisheries in Area 3 from approximately 9 July to 22 July (Weeks 28 and 29), the anticipated peak of the Kwinageese Sockeye migration, as documented in DFO s 218 Integrated Fisheries Management Plan (IFMP).

Cumulative harvests to week ending 3 JUNE are shown in the table below for Food, Social, and Ceremonial (FSC) catches. For the same week ending period, mean cumulative harvests from 2 to 217 are shown for comparison.

Nisga a Fisheries Weekly Update July 218 Page 4

5 Forecast models used were a combination of sibling (Sockeye and Chinook only) and brood year mean returns that project 25%, 5%, and 75% probability point estimates. Mean absolute accuracy for pre season total run predictions to actual are 8% for Nass Sockeye, 69% for Chinook, 52% for Pink, 62% for Coho, and 71% for Chum from 22 to 217. Pre season TRTC forecasts (5% probability estimates) for 218 predict a below average return forecast for Nass Sockeye (377, vs. 57,), Nass Area even year Pink (635, vs. 74,), Nass Chinook (19, vs. 31,), Nass Chum (33, vs. 52,; well below the 45, escapement goal), and above average return forecast for Nass Coho (223, vs. 2,) based on mean TRTC estimates from 1994 to 217. When reviewing Nass salmon returns over a 34 year period ( ), the forecasted returns in 218 are projected to be poor for Chinook (28 th ), Sockeye (27 th ) and Chum (22 nd ); fair for Pink (17 th ); and good for Coho (1 th ) with caution for Coastal Nass Coho salmon returns that returned in low numbers in 215.
