Lake Erie Smallmouth Bass Spatial Ecology

Project Title

Spatial Ecology of Smallmouth Bass in Lake Erie

Project Code

LESMB

Project Duration

February 2022 - December 2027

Project Description

In 2023-2024, ~180 Smallmouth Bass will be captured via angling and electrofishing in the West Basin of Lake Erie and tagged. Scope of movement, spawning site fidelity, and seasonal habitat(s) occupied by tagged fish will be compared between angled (active/high-vulnerability fish) and passive (electrofishing).

Objectives

Quantify daily movement rates for Smallmouth Bass in west and west-central basins of Lake Erie
Compare daily movement rates between high-vulnerability (angling) and low-vulnerability fish (electrofishing).
Determine proportion of tagged fish making long-distance movements between subpopulations and whether a greater proportion of long-distance movers are angler-caught.
Identify seasonally-occupied critical habitats for Lake Erie’s SMB population.
