Apache Lake At Marina Intermittent Veliger Density Time Series Data

Published by Bureau of Reclamation | Department of the Interior | Metadata Last Checked: January 06, 2026 | Last Modified: 2021-03-31T09:19:34Z
Measurements of quagga mussel veliger numbers from Apache 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.
