Title: RECREATIONAL FISHERY IN LAKE SUPERIOR


1
RECREATIONAL FISHERY IN LAKE SUPERIOR
  • Don Schreiner, MNDNR
  • Steve Schram, WIDNR
  • Shawn Sitar, MIDNR
  • Mike Petzold, OMNR

2
History of Recreational Fishing
  • Native Americans first anglers subsistence
  • Commercial fishing began - fur trade subsidized
  • Commercial families started resorts began sport
    fishing

3
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

4
History
  • Increased access roads
  • New harbors/marinas
  • WW II
  • Sea Lamprey

5
History
  • Sea lamprey control
  • Introduced Pacific salmon
  • Larger/safer boats
  • New electronics/technique

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

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
