1 Overview of the Process
PrOACT The Problem - A problem statement was developed by the coaches and the team prior to the workshop at NCTC. Objectives – the coaches and team identified fundamental and mean objectives during the first part of the workshop. Alternatives – examples of alternatives based on changes to hatchery production and stocking strategies were developed by the team during the workshop. Other alternatives related to reducing production costs (changes in fish feed; eliminate heating or pumping of hatchery water…..).

2 Overview of the Process
PrOACT Consequences – The development of a model was initiated by the coaches and the team during the workshop to determine the potential consequences of the different alternatives with regards to effective population size (used as a surrogate for extinction probability) and hatchery budget constraints. The model will be finalized by the end of August, 2013. Trade-Offs and Take Action – Once the model is completed and the alternatives have been evaluated in terms of meeting our Fundamental and Means Objectives, trade-offs will be discussed and evaluated. A decision will be made by October 1, 2013 on how best to manage conservation hatchery production in a manner that meets our objectives and budget constraints. NO DECISIONS HAVE BEEN MADE AT THIS TIME. The decision will be implemented in partnership with our state, federal, tribal, and non-government partners within the auspices of salmon recovery framework and governance structure.

3 U.S. Fish and Wildlife Service
Problem Statement How should the USFWS, in partnership with NOAA, MDMR, PIN and NGO's use Atlantic salmon brood stock and the hatchery system to minimize risk of Atlantic salmon decline in terms of abundance, distribution, and genetic diversity within the three Salmon Habitat Recovery Units given current and future budget constraints? In addressing this problem it is particularly imperative that the decision process be transparent and recognizes the importance and values of our partners.

4 “OBJECTIVES HIERARCHY”
Minimize p(Extinction), (model derived, est. growth rate) Maximize number of habitat units occupied across the SHRUs Maximize p Number of River Basins (In accordance with Broodstock Management Plan and available resources) Maintain genetically and behaviorally distinct GOM population Maximize genetic isolation of river specific stocks Maximize p(genetically fit populations) Minimize p loss of hatchery established family groups Maximize adult returns (# of adult fish) Maximize total viable hatchery product Maximize Effective Population Size Maximize natural spawning (redd counts) Minimize insitu competition between hatchery fish and wild Minimize domestication effects (time in hatchery, # females) Maximize stage specific survival (of individuals) Maximize p(Self-Sustaining Wild GOM salmon) Maximize p(balanced budget) $$ “OBJECTIVES HIERARCHY” Fundamental Objectives Means Objectives

5 Alternatives The following seven alternatives represent examples of how salmon production at Craig Brook NFH and Green Lake NFH can be managed and in some examples changed to meet the fundamental and means objectives of the conservation hatcheries. Each alternative will be evaluated in terms of its consequences to maintaining effective population size, adult salmon returns and work within the budgetary constraints of the hatcheries. The status quo Increase parr in Downeast SHRU (and no Penobscot smolts) 20% reduction across the portfolio Reduced Penobscot river smolt production; increase in Penobscot River parr Increase smolt and parr production in Downeast SHRU; reduce smolts for Penobscot River 6. No fry production or stocking; egg planting in each of the three SHRU’s 7. Add kelts to status quo

6 Alternative #1 1. The Status Quo

7 Alternative #2 2. Increase parr in Downeast SHRU – (no smolts in Penobscot River)

8 Alternative #3 3. Across the board reduction – approx. 20%

9 Alternative #4 4. Reduced Penobscot smolt targets; increase Penobscot parr targets

10 Alternative #5 5. Add smolt and parr stocking to Downeast SHRU; No egg planting in that SHRU

11 Alternative #6 6. Eliminate fry production and stocking; add egg planting to all SHRU’s

12 Alternative #7 7. Add kelts to the Status Quo

13 Summary of Alternatives
Recognizes need to maintain the seven existing broodstocks - to achieve goals of distribution, diversity, and extinction prevention. Alternatives represent different stocking strategies, final production numbers will be determined by USFWS Fisheries budget constraints and availability of resources from partners. Alternatives may be weighted to reflect programmatic objectives and values of partners involved in the decision making process. Highest value will be assigned to production portfolio that meets budgetary goals, minimizes the probability of extinction and maximizes adult returns. Reflect the need for more balance among the broodstocks. Adult returns in the context of the conservation hatchery program should be viewed as a potential source of genetic diversity and the hatchery program is one of several tools necessary to move closer to recovery of the species.

15 Next Steps Further develop and complete the Model - End of August
Test alternatives using the model once completed Reconvene the team in September to discuss trade-offs and make decision Implement decision based on results from short-term model; longer term model development initiated to guide future hatchery production Communicate, communicate, communicate…throughout the proceed to achieve goal of transparency and inclusiveness
