Canyon Lake At Marina Intermittent Veliger Density Time Series Data

Published by Bureau of Reclamation | Department of the Interior | Catalog Last Checked: May 01, 2026 at 10:18 AM | Dataset Last Updated: March 31, 2021 at 09:19 AM
Measurements of quagga mussel veliger numbers from Canyon Lake At Marina. Veligers, the larval stage of dreissenid mussels, are collected with a plankton tow net and preserved with alcohol and buffer. Veligers are identified and counted under cross-polarized light microscopy. Veliger density refers to the number of veligers per cubic meter in the sampled location, as calculated from the total veliger count in the sample and the tow volume taken for sample collection.
