Lake Michigan Salmon Stocking Strategy Process Dennis Eade – Michigan Steelheaders Todd Pollesch – Great Lakes Fishery Commission Advisor (Wisconsin)
2
Collaborative Process The stocking reductions in 1999 and 2006 were determined by agencies and brought to the public for comment. This year’s process involved stakeholders from the beginning.
3
Establishment of Goals and Objectives (Work Shop 1) Stakeholder Meetings April 2011 in Michigan June 2011 in Wisconsin Stakeholders represented various Lake Michigan angling organizations from Indiana, Illinois, Wisconsin, and Michigan. Both Stakeholders and Agencies Stated Goals and Objectives
4
Goals and Objectives Stakeholder Maintain ecosystem balance Maximize harvest and catch rates Maximize sport fish potential Maximize sustainable benefits Protect forage biomass Minimize collapse of the forage base Avoid loss of native species Provide larger Chinook (16-18 lbs for age 3+) Maintain stable fishery Maintain a diverse fishery
5
Goals and Objectives Agency Maintain acceptable catch rates (8-12 fish/100 hrs) Maintain a diverse fishery (>50% Chinook; >25 % other species) Maintain good salmon growth (age 3 Chinook 7 kg [15.4 lbs], in late summer) Maintain alewife at or below undesirable levels Maintain adequate spawning stock biomass for lake trout
6
Core Stakeholder Group Each agency chose individuals that: Had good knowledge of the Lake Michigan ecosystem. Represented a large organization. Had the ability to network and share information. This Stakeholder Group also Participated in 2 full day workshops.

Work Shop 2 Overview November 5 th Portage, Indiana Discussed How Managers Make Decisions Reviewed Chinook salmon abundance, natural reproduction, growth, condition, and health Reviewed prey abundance and forecasts Learned about the Lake Michigan Decision Analysis Model Developed scenarios to evaluate and refine the model
9
Work Shop 3 Overview January 23 rd Chesterton, Indiana Reviewed Lake Michigan Decision Analysis Model outcomes Discussed model outcomes Began discussions about stocking strategies
10
Stocking Strategies and Options Three Stocking Strategies and a total of 16 stocking options were evaluated based on: Goals and Objectives Risk tolerance for low alewife abundance (20% or less) Based on email comments from stakeholders and agencies, four options were adopted for further public review
11
Next Steps Communicate the State of Lake Michigan to the Public Further Discussion of the proposed stocking options Assist agencies in making an informed decision to meet fishery goals and objectives
