    Passive and active tracking data of several fish species movement around Lock and Dam 2 and Lock and Dam 8 (2016 to 2018)
    (2018-12-19) Finger, Jean S; Riesgraf, Andrew T; Zielinski, Daniel P; Sorensen, Peter W; js.finger@yahoo.fr; Finger, Jean Sebastien; Sorensen Laboratory
    This data set has 2 main components: First we investigated the movement of several fish species around and across a Mississippi River lock and dam: Lock and Dam 2. Approximately 200 fish were tagged and released below this structure and were tracked to determine both whether and when they passed through this structure, using an array of passive receiver. Additionally, some of these fish were actively tracked (acoustic and radio) below the spillway gates of lock and dam 2 to investigate their movements and approach behaviors. Second, we investigated the efficiency of a sound barrier installed on the downstream side of the lock chamber of Lock and Dam 8. 160 common carp were tagged and released below a Mississippi River lock and dam (Lock and Dam 8) and tracked using a passive receiver array. This experiment was designed to determine whether fish were entering the lock chamber with the sound barrier on or off. Locks and dams are challenging environments for tracking technology (e.g. difficulty to detect tags in high turbulent water) and we advise to contact the authors or read publication/report associated with this data set for more details about technological limitations.

    Raw Data for Bighead Carp, Common Carp and Largemouth Bass Light Avoidance Studies in a Laboratory Flume (2018-2019)
    (2024-04-25) Dennis III, Clark E; Sorensen, Peter W; cdennis2@illinois.edu; Dennis, Clark; Sorensen Laboratory
    Raw data of fish passage rates and light measurements from high-intensity light avoidance tests of bighead carp, common carp and largemouth bass in a laboratory flume. This data is made available to support a open access publication submitted to Management of Biological Invasions entitled "High-intensity light blocks bighead carp passage in a laboratory flume".
