Lake Erie Bathymetry Map

Objectives To explore walleye growth, movement and habitat quality in Lake Erie using tagging data, bio-data, catch rate data analyses, and bioenergetics modeling. Hypothesis Walleye migrate to areas of high growth rate potential (GRP) and grow faster there.

Tag Recovery Location Map ( ) Boundary of basins (Ludsin, S.A. et al, 2001)

Walleye Biological Data From Ontario MNR Surveys,

Commercial CPUE Patterns (1999) in ON Waters

Sport CPUE Patterns (1999) in U.S. Waters

NOAA CoastWatch Data: Lake Erie Water Surface Temperatures, August

Forage Fish Density Index U.S. Agency Trawl SurveysOMNR Gillnet Surveys

Methods Movement - Map and model spatial pattern of commercial and sport CPUE by month and year. - Analyze tagging data by stock, and explore distribution of recapture locations. Growth - Estimate growth rate and length at 50% mature from bio-data. - Walleye Bioenergetic Growth Model.

Commercial CPUE patterns (1999) indicate that walleye migrate to EB in June, and migrate back to WB in September

Ordinary Kriging of Commercial CPUE in May-Nov, 1999

Most (78%) Recaptured Walleye were from 5 Tagging Sites in WB and 1 Site in EB

Large Walleye Tagged in WB were recaptured in CB and EB; EB-tagged Walleye Don’t Migrate

Walleye Recaptured in CB and EB Were Larger, Regardless Where They Were Tagged

Growth Rates of Age-2 and Older Walleye Appear Fastest in Eastern and Central Basin

WB Walleyes Mature at larger size than in EB. Females Mature at larger size than Males.

Walleye Bioenergetic Growth Model Estimate growth based on lake temperatures and prey densities. Assume Higher growth rate indicates better habitat quality

Walleye Growth Model Framework Growth = Consumption - Losses (Losses = Respiration, Egestion, Excretion) Consumption is a function of temperature, walleye weight and prey fish density

Gillnet CPUE Indicates Spatial Overlap is High Between Walleye and Clupeid Forage

Walleye Growth Model Predictions Correlate with Walleye Movement patterns, but not with Commercial CPUE data.

Results Walleye in the EB and CB appear to grow better and mature at smaller sizes than in the WB. Mostly large, female walleye migrate from WB to EB. Why??? Perhaps to increase fitness, i.e. increase female growth and fecundity.

Future Work Refine Walleye Growth Model using CPUE data on depth and temperature where walleye forage. Examine effects of decadal ( ) changes in walleye density on walleye growth and movement.
