Bioacoustics in the Great Lakes

A “sound” strategy for learning about fish:

(via A. Rice / The CornellLab)

Aaron Rice, of Cornell’s Bioacoustics Research Program, tracks fish populations and behavior. He does it using sound.

Rice: “The advantage of using sound as a survey method is that with digital recording technology that’s available now you can take a hydrophone, connect it to a essentially waterproof computer with a whole bunch of batteries and deploy it at the bottom of the lake let it record for six months to a year and then come back and start your analysis and so you have 24/7 audio coverage of a particular environment.”

Rice says this information can be used for things such as placing off-shore windfarms in areas where they would have a minimal impact on fish life.
