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.
This report, released by the Energy andBiodiversity Initiative (EBI), is the resultof a collaborative effort by representa-tives of the nine member companiesand conservation organizations of theInitiative. The views expressed hereindo not necessarily represent the viewsof every EBI member.EBI members recognize that there is a continuing public debate aroundbiodiversity conservation and oil andgas operations. Although EBI was notintended to resolve all the issues in-volved in this debate, we believe theEBI products and process will make a significant contribution to con-structive dialogue to accompany thatdebate.

In this experimental series we studied the swimming capabilities and response of grass carp (Ctenopharyngodon idella) larvae to flow turbulence in a laboratory flume. We compared three different experimental configurations, representing in-stream obstructions commonly found in natural streams (e.g. a gravel bump, a single vertical cylinder, and patches of submerged rigid vegetation). Grass carp larvae (post gas bladder emergence) were introduce to each experimental configuration and subjected to a variety of hydrodynamic forces of different magnitudes and scales. We varied the flow velocities and water depths and found threshold values of turbulent kinetic energy and Reynolds stresses that triggered an apparent...
