2017 Returning Sockeye are a product of 2012/2013 spawners
The preseason forecast that we are basing this meeting off of is calculated by looking at the number of returning 3 year old jacks and 4 year olds from previous years and using that as an index for returning 4 & 5 year olds this upcoming season

Low Returns & Food Fishery Considerations
[ Comparable to 2013 : 463,500 Sockeye ] Skeena Sockeye Preseason “Just A” Forecast 2017: 594,678 Sockeye (284, ,241,622 uncertain till July) Returns below 550,000 requires conservation discussions Skeena First Nation’s Food Fishery : 150,000

Overall Skeena Sockeye Run Timing

2014-2016 Later Timed Sockeye= Alaskan % back up
Trends in Skeena Sockeye Exploitation Rates (% of the return) Later Timed Sockeye= Alaskan % back up

Pacific Salmon Treaty CHAPTER 2 Northern BC and SE Alaska
Skeena/Nass sockeye
11
Skeena Sockeye The US shall manage the District 104 fishery prior to Statistical Week 31 to: achieve a catch share of 2.45 % Skeena/Nass sockeye Annual Allowable Harvest , ~80% of Skeena sockeye were past D104 and this is the timing that is still used today. The PST has no Skeena sockeye management restrictions on Ak in Wk 31 and later.
12
District 104 District 101 Just so where we know where we are talking about. The grey is where fisheries occur in Alaska that impact Skeena sockeye.
13
Impacted Skeena Sockeye Migration
District 104 Impacted Skeena Sockeye Migration This shows the migration route Skeena sockeye intercepted in Alaskan fisheries. Almost all of Sk sy interception occurs in D104 with small catches in D101. D104 is discussed in the treaty for Skeena sockeye.
14
Alaskan Exploitation 2008-12 Run norm – ave exploitation
Avg. 5% of Tot Run Run early – low exploitation Avg. 3% of Tot Run Run late – high exploitation Avg. 14% of Tot Run To 2012 In general before Wk 31 the Alaskans do pretty good on following the treaty. 1.74% average of AAH It is Wk 31 onward that the interception of Skeena sockeye has no management measures in the treaty and this increases the overall harvest rate on Skeena sockeye. ~9% average of total run In 2012 Skeena sockeye were early and the Ak harvest rate on Skeena sockeye was 2.74% of the total run. Runs were later. Only about 55% to 60% of run past D104 prior to Wk 31

16
Climate News Global –Regional – Local Last 3 years has been different
El Nino & “The Blob” Conditions – no widespread sockeye failure but did mess with: size for age groups of some populations – like Skeena/Nass return timing Impact fresh water conditions
17
Recent Ocean Conditions
The blob is essentially a mass of warm water – you can see in January it was up to 3 degrees above normal temperatures and it moved in towards the BC coast in 2015 and appears to be returning to normal temperatures
18
Impacts of warmer ocean temperatures:
Warmer temperatures negatively changed the zooplankton food that sockeye eat It can impact the fish’s body function Smaller Sockeye Wide swings in survival both marine and in fresh water Smolts that went into the ocean in 2014 & 2015 produced very low age 3 and poor age 4 sockeye returns for 2016 Skeena and Nass 2015 conditions – impacts to sockeye returns
19
Migration Changes It can also influence return timing if sockeye need to swim further north to be in cooler water Later & Smaller Sockeye Higher Harvest by Alaska
21
Fresh Water Conditions
Multiple years of warm ocean conditions influence land and freshwater ecosystems. Low water, high water temperatures, strange distribution of rain or snow and early spring melt have all had consequences for the different life stages salmon For Skeena, marine survival declines have added to the ongoing issues of apparent poor/low freshwater production from Babine Lake. Studies ongoing…
22
Concern is Skeena-Wide
23
Discussion What are our Options?
24
First Nations 2017 Draft Food Fish Proposal
Background on working group Key Points: Healthy growth of salmon populations into future Prioritization of First Nations’ Access & Allocation for Food Fisheries Mutual respect for all Skeena First Nations to meet their food fish needs Pre-season forecasting leaves room for us to err on the side of caution to avoid creating irreversible damage to the salmon populations that sustain us
25
Skeena First Nations Technical Committee
Draft Proposal
26
First Nations 2017 Draft Food Fish Proposal
Looking At the Numbers Pre-season forecasting leaves room for us to err on the side of caution to avoid creating irreversible damage to the salmon populations that sustain us
27
Discussion Points Food Needs and Options
How Gitksan information can be used if we take a conservation approach Other 2017 Fisheries Concerns besides sockeye Next Steps
