Summary

Data collected from a comprehensive set of hydrodynamic experiments conducted with live grass carp eggs and larvae, to evaluate drifting and swimming patterns with 3 different in-stream obstructions: (1) a gravel bump, (2) a single cylinder, and (3) submerged vegetation. The hydrodynamic behavior of eggs and larvae with each obstruction was continuously monitored for about 85 consecutive hours. Transient spatial distributions of the locations of eggs and larvae across the water column were generated for each flow scenario.

Purpose

The data were collected to better understand the response of grass carp to flow and turbulence regimes during early life stages. This information is fundamental to monitoring and controlling their spread. In addition, the data will inform field collection of grass carp during early life stages, and guide the design of alternative approaches to control the dispersal of this invasive species in North America.
