Abstract

Anthropogenic stressors negatively impact natural populations and lead to their declines. Ex-situ conservation practices are then becoming essential tools to maintain biodiversity and prevent extirpation of vulnerable species. One species currently undergoing restoration efforts, to supplement Huron-Erie Corridor populations, is the imperiled lake sturgeon (Acipenser fulvescens). Knowledge is limited on more effective supportive breeding programs for lake sturgeon. My research aims to explore whether a supportive breeding program can be effective by focusing on a potential barrier to success. Some adult lake sturgeon rely on home site fidelity to find appropriate spawning grounds. To ensure successful restoration of captively released sturgeon, I will examine whether scent enhancement can impact this behaviour during early development using choice flume behavioral trails. The results of these studies will have implications for future conservation groups in rearing effective lake sturgeon populations while enhancing research in successful supportive breeding of species at risk.
