Long-Term Goals: I plan to continue researching thiamine deficiency in fish, while completing my master’s degree at SUNY Brockport. In the long term, I hope to apply my education in the field of aquatic ecological management and may pursue a PhD.
Project Description:
Thiamine Deficiency Complex (TDC) impairs health and recruitment in salmonids across the Great Lakes, yet its potential behavioral effects remain unknown. While the primary physiological impacts of TDC are well-documented, potential secondary effects on fish behavior remain unexplored. Behavioral impairments induced by TDC could have significant ecological consequences, affecting foraging efficiency, predator avoidance, and overall survival. My project examines differences in movement patterns between thiamine-treated and untreated steelhead trout using EthoVision, a video tracking software. Steelhead trout eggs were divided into two groups at fertilization: one treated with thiamine mononitrate and one left untreated. Juveniles from both groups were reared under identical conditions and observed in a controlled experimental arena. EthoVision was used to quantify key behavioral metrics, including mobility state (active vs. inactive), distance traveled, acceleration, and angular velocity. Because thiamine deficiency affects neurological function, untreated fish are expected to show reduced mobility, impaired swimming patterns, and altered responsiveness. These findings will help inform hatchery management practices and efforts to support wild steelhead populations.
How will this experience contribute to your future success?
This project has given me the opportunity to immerse myself in research and build a strong foundation for my master’s work. It has taught me how to operate independently in a lab setting while also recognizing the value of collaboration when needed (seriously, it’s important). Ultimately, this project will benefit both my future education and my career by providing the skills and confidence necessary to succeed in research and beyond
This project was made possible thanks to the generosity of the Brockport Foundation.
