The California Department of Water Resources and UC Davis are advancing a captive rearing program for the endangered Longfin Smelt in Yolo County. - The program has successfully reared fish from the larval stage, a critical breakthrough.
- The Longfin Smelt is an indicator species, reflecting the health of the Sacramento–San Joaquin Delta estuary. - Threats include entrainment, water quality issues, and limited food supply.
- The Longfin Smelt Science Plan guides research and management strategies for the next decade. This coordinated effort aims to stabilize the species and support Delta ecosystem health.
