Invasive Carp Species Section
Bighead carp ( Hypophthalmichthys nobilis ) and the closely related silver carp ( Hypophthalmichthys molitrix ) (together, the bigheaded carps) and black carp ( Mylopharyngodon piceus ) are rapidly expanding in numbers and distribution in the Mississippi and Missouri River basins.
Starved Rock navigation lock fish clearing hydroacoustic data, Illinois River (2020)
These datasets (e.g., 'Starved Rock fish clearing_multi-beam imaging sonar fish data_Pre-clearing_Sonar-s1.csv') include exported information (e.g., fish detection counts) from processed fixed-location multi-beam imaging sonar and mobile side-scan sonar data. Fish abundance in the navigation lock was determined using mobile side-scan surveys, while multi-beam imaging sonars were used to determine
Fish collection and hydrological data for oxbows in western Iowa
The data set associated with this metadata is included in three separate csv files: 'Occupancy_Data', 'Stage_Raw', and 'Flood_Stage_Height'.
'Occupancy_Data' was used to fit the dynamic occupancy models and includes 17 columns: Time: time periods numbered 1 to 5; 'Oxbow': individual oxbows numbered 1 through 10; 'OxbowName': the name of each oxbow; 'Species': species encountered during sampling
Precision of four calcified structures for age estimation of Black Carp
ObjectiveBlack Carp Mylopharyngodon piceus is an emerging invasive species in North America with an expanding population in the Mississippi River basin. Current aging methods use a suite of structures for age estimation, and a single structure is needed to minimize processing time, to maximize consistency of age and growth measurements, and to allow for back-calculation of individual fish length a

Application of electricity and underwater acoustics to clear fish from a navigation lock during maintenance
The presence of fish within navigation locks can introduce an environmental challenge for construction crews when maintenance is required. This study examined the effectiveness of a dual-deterrent fish herding technique using electricity and acoustic stimuli to reduce the abundance of fish within a navigation lock before a scheduled dewatering for maintenance. Fixed-location multi-beam imaging so
