Entrainment of Semi-Buoyant Beads and Razorback Sucker, Xyrauchen texanus, Larvae into Flood Plain Wetlands of the Middle Green River, Utah

We released semi-buoyant beads and marked razorback sucker larvae into the Green River during spring run-off in 2004, 2005, and 2006 to evaluate drift characteristics of larvae and beads into flood plain wetlands. Based on drift rates and capture patterns, our findings from 2004 main channel only sampling suggested that beads and tetracycline-marked fish larvae were reasonable surrogates for one another based on similarities in drift capture patterns. We also captured substantial numbers of unmarked, wild-produced razorback sucker larvae in 2004. This demonstrated that stocked adult fish were successfully reproducing and that another spawning area may exist downstream from Razorback Bar (now named ?Escalante Bar?),...
