Retention Rates of 2.0-Mm Fine-Mesh Traveling Water Screens: Theoretical Vs. Empirical
The effectiveness of 2.0-mm fine-mesh screens at retaining larval fish was evaluated in a laboratory study. Test species included bigmouth buffalo (Ictiobus cyprinellus), bluegill (Lepomis macrochirus), common carp (Cyprinus carpio), golden shiner (Notemigonus crysoleucas), and white sucker (Catostomus commersonii). Theoretical estimates of retention compared strongly with the testing results for four of the five species. These results support the accuracy of the theoretical model and indicate that measurements taken from in situ ichthyoplankton samples may be sufficient to predict retention rates at CWIS in the place of empirical data.
