| Delta Smelt Culture Facility - The University of California, Davis, and the State, working
with federal agencies, operate a Delta smelt culture laboratory located at the Department
of Water Resources Banks Pumping Plant in the Delta. UC Davis rears and provides over 20,000
juvenile and adult fish annually to researchers carrying out elements of the POD
investigation and evaluating ways to improve the performance of existing and new fish
screening facilities. These research fish are the progeny of wild fish collected in the
Delta in 2006, and with the curtailment of the collection of wild fish due to the
declining population they are now the only source of live research fish. Research is also
carried out at the UC Davis fish culture facility into the physical and biological
requirements of delta smelt. |
