Barriers:
How does one
modify traditional
infrastructure in
order to effectively
facilitate fish
movement and still
meet the other
competing criteria?

Conceptual idea: fill in the fine scale
fish/hydraulics relationship data gap
USFWS, 1982
Goal: design with
empirical evidence,
moving to path
prediction, decision
theory or agent based
models
Wisc.DNR 2005
Trappers: Let the animal’s tracks
show you how they behave for the
given conditions – then you can
predict future movement
Data Collection Aims:
1) Swim Paths of Small Fish:
• Distance to solid surface
• Exposure to water velocities
• Exposure to turbulent kinetic energy
• Exposure to Reynolds stresses
-Measured at many discrete positions
along entire swim path for each fish
2) Qualitative Analysis: Possible observation
of novel fish behaviors
Project Apparatus
Western Blacknose Dace (R. obtusus)
-UB Institutional Animal Care and Use

Only 40 % of time chose lower turbulence,
analysis ongoing, conclusions forthcoming
Summary
-Observed novel fish behaviors that should be
followed up with quantitative studies
-Developed an approach to investigate the
relationship of turbulence and velocity on fish
swim paths
-Completion of data analysis will become the
basis for more comprehensive studies
