Skeena Fisheries Review and Update Ryan Whitmore Rodney Harris Gitksan Watershed Authorities

2017 Skeena Sockeye Review Forecasted Return Pre-season “forecast” was ~595,000 large Sockeye Range: 284k < 595k < 1.24M Age distribution Forecast estimated 20% age 4 and 80% age 5 Low proportion of age 4 due to record low proportion of jacks in 2016 (N=5,435) Raises Concern > 2013 return (585k forecast), < target escapement of 1.05M Reduction in productivity……

First Nations Planning 2017 OBJECTIVE To meet the minimum benchmark of ≥240k wild sockeye spawners All First Nations within the Skeena collectively collaborated and successfully implemented specific management objectives Raise the minimum aggregate escapement from 400k to 600k Should enable wild stocks to meet minimum escapement levels FSC Fishers to use mesh size ≥7” to ↓ impact on Sockeye

Gitksan FSC Catch Annually, Gitksan and Wet’suwet’en Nations have a combined allocation of 100k Sockeye With ≥7” mesh rule in place from June 18th to August 5th Gitksan harvested ~7k sockeye ~80% ↓ when compared to those weeks in 2016 <45% effort (# of net sets) from 2017 to 2016 Reason: limited access to ≥7” mesh nets?

Gitksan FSC Catch On August 5th it was estimated >600k sockeye passed by Tyee The following day (August 6th) FNs would now target sockeye ~75% of Gitksan FSC Fishers switched over to nets with <7” mesh ~21k large sockeye were harvested from August 6th to September 9th ~23% ↑ in total catch compared to 2016 though effort (# of net sets) was slightly higher than in 2016

Gitksan FSC Catch Catch Effort 2017 ~28k 1,844 Average (2005-2016) 2017 Catch and Effort compared to the 12 year average (2005-2016) The Gitksan and Wet’suwet’en Nations are clearly not harvesting their Skeena allocation of 100k sockeye Catch Effort 2017 ~28k 1,844 Average (2005-2016) ~54k 2,436

Skeena FNs FSC Catch 2017 Catch Gitksan & Wet’suwet’en ~28k Lake Babine Nation (including Yech & Takla) ~7k Below Tyee (Tsimp, Met & Area 4 Kit) ~6k Total ~41k Skeena First Nations are clearly not harvesting their food fish needs.

2017 Skeena River Sockeye Escapement Total escapement was 989k, DFO forecasted 595k Estimated ~298k were wild stocks Remember: minimum benchmark for wild Skeena sockeye is 240k Levels of Uncertainty 2013; forecasted 585k, only ~430k returned Only ~380k returned to spawn

2017 Skeena River Sockeye Escapement - Wild ↓ fishing effort benefited some small wild populations Lakelse Lake – Average return (~5k) Mcdonell Lake – Largest return on record (~8K) Nanika Lake – Above average (~15k) Slamgeesh Lake – Greater than forecasted (~350) Azuklotz Lake – Largest return on record (~7k)

2017 Skeena River Sockeye Escapement Age Distribution Expected: 20% at age 4 and 80% at age 5 Actual: 4% at age 4 and 92% at age 5 Size at Age Sockeye smaller than expected Age 5 fish are the size of age 4 fish Reduction in productivity

Skeena Sockeye Productivity Trends In theory, Pacific Salmon have a recruitment rate of 2:1 =

Skeena Sockeye Productivity Trends In recent years, Skeena has been witnessing roughly a 0.5:1 = WHY? Problematic ocean and fresh water conditions

2017 Skeena River Sockeye Escapement RECAP: Return greater than expected but……. Age distribution is alarming Fish are starving: size at age Reduction in productivity

2018 Forecasted Return Similar to 2017……Range: 283,712 < 645,112 < 1,466,874 Concern: though > 600k < target escapement of 1.05M Age distribution estimated to be highly skewed towards age 4 fish Meaning the 2013 cohort has completely failed Size at age to be similar to 2017 a “phenomenon” seen since 2014 In 2017 we saw an escapement of 989k sockeye with 298k being wild….will 645k sockeye be comprised of at least 240k wild fish?

Skeena Chinook 2017 Estimated return of ~33k Exploitation Rates (Chinook Harvested) Ocean 26% (~8,500) In-River Sport 1.9% (~600) Terminal FNs 13.8% (~4,500) In TOTAL ~42% of Skeena Chinook harvested in 2017 This means estimated escapement was only ~19k Lowest ever recorded on Skeena

FN’s Chinook Harvest 2017 In-River FN’s harvested an estimated 4,554 Chinook in 2017 Nation Chinook Harvested Exploitation Rate Gitksan 3,524 10.6% Kitsumkalum 453 1.4% Wet’suwet’en 367 1.1% Kitselas 210 0.6% Gitksan FSC fishers harvested 1:3 Chinook that entered the Gitksan Territory in 2017 Only ~9k Chinook made it to the spawning grounds within or above Gitksan Territory

Skeena Chinook 2018 Estimated to be similar to 2017; ~33k Precautionary measures already set in place No sport fishery within the Skeena Watershed No commercial fishery near the mouth of Skeena River Precautionary measures being pursued Reduction in harvest of Skeena Chinook in ocean sport & commercial fishery Gitksan and Wet’suwet’en Nations are pursuing a complete closure

FN’s Draft Plan Sockeye 35 (1) Fisheries closures trigger levels will be maintained at 600,000 Commercial fisheries that intercept Skeena sockeye will start closed FN’s FSC fisheries will open if in season abundance is greater than expected Unlikely to occur before July 26 Recreational fishing (tidal and in-river) that target Skeena sockeye will start closed Will open once 1.05 million Skeena sockeye have returned to the Skeena
