History of Recreational Fishing Native Americans – first anglers – subsistenceNative Americans – first anglers – subsistence Commercial fishing began - fur trade subsidizedCommercial fishing began - fur trade subsidized Commercial families started resorts began sport fishingCommercial families started resorts began sport fishing
3
History of Recreational Fishing Much of first angling experience was from shore/streamMuch 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 fishermanFirst charter captains were commercial fisherman

History Increased access roads New harbors/marinas WW II Sea Lamprey

6
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
7
Waters of Lake Superior Bays 0-240 ft (0-80 meters) > 240 ft (> 80 meters)
8
Creel or Angler Surveys Pressure – angler hours Number of fish harvested or caught CPUE – catch per effort or no. of fish/angler hr
9
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

15
Distribution of Major Salmonids in Catch from U.S. Waters of Lake Superior 1990-2000
16
Distribution of Major Salmonids in Ontario Waters of Lake Superior 1987-1999

21
Number of Charter Captains in U.S. Waters of Lake Superior
22
Comparison Between Overall Sport and Charter CPUE for U.S. Waters of Lake Superior
23
Comparison of Charter CPUE Among States
24
Estimates of Fishing Pressure in Days Among Upper Great Lakes ****From Bence and Smith (1999)
25
Comparison of Salmonid CPUE Among Upper Great Lakes for Salmonids
26
Comparison of Charter CPUE Among Upper Great Lakes
27
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
28
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
29
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
30
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
