You Can Swim…But You Can’t Hide!
Using Sonar to Evaluate Fish Movement on the Upper Miss
BY JENNA MERRY, LA CROSSE FWCO
Lock and Dam 19 has been an important structure in slowing the upstream progression of Asian carp populations in the Upper Mississippi River.
The objective of the ARIS project is to collect this data about fish behavior. Specifically we aim to identify the key areas of fish congregation in and around the lock and evaluate the movement patterns of fish in and out of the chamber gates and ports.
A thorough review of the imagery data will identify behavior and movement patterns of fish in and around the lock. The results will help advise future implementation of deterrent technology at Lock 19 and the ARIS could then potentially be used to further evaluate the effectiveness of that technology once it is implemented.
