Description
Matthew Balazik and Douglas Clarke track young Atlantic sturgeon near an active river dredge, in work from 2024. The fish has declined across its range, and channel dredging is one suspected threat. Recovery plans need proof of how young fish react to working dredges.
Across 2019 and 2020, teams caught and released 268 young fish near a suction dredge in the James River. Catch rates near the dredge matched those at a calm reference site. Nets set downstream for a month showed no clear drop either. Twenty-nine fish carried sound tags that tracked their moves. Tagged fish fed within a short swim of the dredge, showing little sign of flight.
