This project, initiated in 2023, uses acoustic telemetry to monitor movements and habitat use of bigheaded carp (Hypophthalmichthys nobilis and H. molitrix) in the lower Red River and its tributaries in Oklahoma, Texas, and Arkansas. Located at the upstream edge of their range in the basin, this area has adult carp present but no officially documented recruitment, possibly due to limited past monitoring or infrequent suitable spawning conditions; therefore, a primary objective of this project is to identify potential spawning movements and locations. Tagged fish are tracked year-round to assess movement in relation to species, sex, size, hydrology, season, and time of day. The project is ongoing and currently expanding receiver coverage and tagged fish numbers.
