The U.S. Geological Survey (USGS) California Water Science Center (CAWSC) is offering a funding opportunity to a partner of the Cooperative Ecosystems Studies Unit (CESU) Program. For a project titled Studies Assessing Factors that Influence Spawning Migration Behavior and Reproductive Condition of Delta Smelt (Hypomesus transpacificus) in the Sacramento-San Joaquin Delta. This project will coordinate closely with a project titled Studies on the Role of Zooplankton Density and Feeding Success during the Spawning Migration of Delta Smelt in the Sacramento-San Joaquin Delta. The USGS effort is comprised of several interrelated study components, three of which are included in this announcement: 1. Determine fish health by linking conditional factor and biochemical and histopathological biomarker responses; 2. Determine age of fish/assess reproductive performance of fish by otolith microchemistry and staging of oocyte development and maturity; and 3. Use the data to revise behavioral components of particle tracking modules for use in individual-based models (IBMs) and other population models for delta smelt.
