Ontogenetic changes in swimming speed of silver carp, bighead carp, and grass carp larvae-Data

Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: May 05, 2026 at 08:36 PM | Dataset Last Updated: February 08, 2024 at 12:00 AM
We measured ontogenetic changes in routine and maximum swimming speeds of bighead, grass, and silver carp larvae. Daily measurements of routine swimming speed were taken for two weeks post-hatch using a still camera and the LARVEL program, a custom image-analysis software. Larval swimming speed was calculated using larval locations in subsequent image frames and time between images. Using an endurance chamber, we determined the maximum swimming speed of larvae (post gas bladder inflation) for four to eight weeks post-hatch.
