RECREATIONAL FISHERY IN LAKE SUPERIOR Don Schreiner, MNDNR Steve Schram, WIDNR Shawn Sitar, MIDNR Mike Petzold, OMNR
History of Recreational Fishing • Native Americans – first anglers – subsistence • Commercial fishing began - fur trade subsidized • Commercial families started resorts began sport fishing
History of Recreational Fishing • Much of first angling experience was from shore/stream • Fly fishing • Elite class of anglers • Superior Fishing-Robert Barnwell Roosevelt-1865 • First charter captains were commercial fisherman
History • Increased access roads • New harbors/marinas • WW II • Sea Lamprey
History • Sea lamprey control • Introduced Pacific salmon • Larger/safer boats • New electronics/technique
Characteristics of Fishery • Stream fishery in spring and fall • Targeted at introduced salmonids • Lake fishery relatively near shore - summer • Bottom bouncing and jigging for lake trout • Planner boards for salmon • Bays and estuaries - seasonal • Cool water species, splake, brown trout
Waters of Lake Superior Bays 0-240 ft (0-80 meters) > 240 ft (> 80 meters)
Creel or Angler Surveys • Pressure – angler hours • Number of fish harvested or caught • CPUE – catch per effort or no. of fish/angler hr
Status – Creel Surveys • Wisconsin – 1972 – 2000 May 1 – Sept. 30 • Minnesota – 1972 – 2000 Memorial W.E. – Sept. 30 • Michigan – 1987 – 2000 Standard sites May 1 – Sept. 30 • Ontario – Intermittent – selected sites - diaries

Estimates of Fishing Pressure in Days Among Upper Great Lakes ****From Bence and Smith (1999)
Comparison of Salmonid CPUE Among Upper Great Lakes for Salmonids
Mean Size of Major Salmonids Caught Among Upper Great Lakes **Estimates for L. Huron from 1990-1998, L. Michigan from 1995-1997, L. Superior from 1990-2000. For each lake, data were from lake-wide creels
Mean Catch Composition Among Upper Great Lakes ****L.Huron Estimates from 1986-1998, L.Michigan Estimates from 1991-2000, L. Superior Estimates from 1990-2000
Summary – Upper Lakes Recreational Fishery • Fishing pressure much lower on Lake Superior • CPUE of sport and charter fishery for Lake Superior equal to or greater than in Lakes Michigan and Huron • Catch composition dominated by lake trout in L. Superior, chinook salmon in L. Huron and rainbow trout in L. Michigan • Average size of all fish smaller in L. Superior
Summary– Lake Superior Recreational Fishery • Fishing pressure has decreased since late 1980s, while catch rate has increased • Annual catch of all salmonids averaged approximately 70,000 fish from 1990 - 2000 • Average CPUE is 0.15 for all salmonids from 1990-2000 • Approximately 67% of catch composed of lake trout, 17% coho and 8% chinook salmon
