Project Summary

We postulate that juvenile lake sturgeon (Acipenser fulvescens) learn stream-specific odors that may guide homing in spawning adults. By defining how and when olfactory imprinting occurs, we expect to inform existing and future restoration strategies that promote recruitment and genetic diversity for populations of lake sturgeon in the Great Lakes.
