Integrating Hydrodynamics and Fish Vital Rates into Indices of Entrainment for Endangered Smelts at the Barker Slough Pumping Plant [PDF]

Fish losses to entrainment in water diversions in the Sacramento–San Joaquin Delta have been a long-standing conservation concern. We evaluated Delta Smelt (Hypomesus transpacificus) and Longfin Smelt (Spirinchus thaleichthys) entrainment risk associated

Comparing and Integrating Fish Surveys in the San Francisco Estuary: Why Diverse Long-Term Monitoring Programs are Important [PDF]

, 2020
Many fishes in the San Francisco Estuary have suffered declines in recent decades, as shown by numerous long-term monitoring programs. A long-term monitoring program, such as the Interagency Ecological Program, comprises a suite of surveys, each ...
