Jessica Z. LeRoy Michael Berutti P. Ryan Jackson Marian M. Domanski 2021 <p>The Fluvial Egg Drift Simulator (FluEgg) was developed to simulate the transport and dispersion of invasive carp eggs and larvae in a river. FluEgg currently (2020) supports modeling of bighead carp (<i>Hypophthalmichthys nobilis</i>), silver carp (<i>H. molitrix</i>), and grass carp (<i>Ctenopharyngodon idella</i>), with the planned addition of black carp (<i>Mylopharyngodon piceus</i>) once developmental data are available. FluEgg integrates the biological development of invasive carp eggs and larvae with a particle transport model that simulates the advection and dispersion of the eggs and larvae based on user-supplied one-dimensional hydraulic conditions. FluEgg can be used to evaluate the hydrodynamic suitability of a river for invasive carp spawning, to inform sampling and monitoring efforts, and to identify the most likely spawning areas of captured eggs or larvae.</p> application/pdf 10.3133/ofr20211052 en U.S. Geological Survey Fluvial Egg Drift Simulator (FluEgg) user’s manual reports
