Movement Patterns of the Native, Procambarus Clarkii, (Crustacea: Decapoda) in West-Central Texas

This study was undertaken to determine movement patterns and burrow occupancy of the red swamp crayfish, Procambarus clarkii, at Anson Springs in Tom Green County, Texas. This study represents the first use of radio telemetry within P. clarkii’s native range. Eight specimens (three males and five females) were fitted with radio transmitters and their locations were tracked in-stream six times a day, from August 10–24, 2017. Results suggest that reproductive males undertake fewer movements than females during the day and the night. Also the majority of movements for both males and females occur after 1800. Burrow occupancy suggests that males are more often found in bank burrows while both males and females are less often observed under boulders.
