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

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
