August 4 Brown Bag – Assessing Extinction in Fishes: Preparing for Extinction of Delta Smelt

One of a series previewing the upcoming State of Bay-Delta Science 2016


Thursday, August 4, 2016

12:00 – 1:00 p.m. PDT


Park Tower Building
2nd Floor Conference Room
980 Ninth St., Sacramento, CA 95814


Peter Moyle, Ph.D., UC Davis Distinguished Professor Emeritus of fish biology
Jason Baumsteiger, Ph.D., UC Davis Postdoctoral Researcher: evolution and systematics of native fishes - Peter Moyle and Michael Miller labs


Drs. Moyle and Baumsteiger will discuss general aspects of assessing extinction, focusing on native fishes of the San Francisco Estuary including the Delta smelt. They will propose six extinction categories: mitigated, regional, native range, wild, visual, and global. To prevent premature delisting, they recommend a waiting period based on generation time rather than a fixed number of years.


The extinction of a species is a major consideration in balancing water supply and environmental needs. It’s usually regarded as a “yes/no” state. But, its determination can be quite complicated.


This Brown Bag seminar is one of a series previewing the upcoming State of Bay-Delta Science 2016. Coordinated by the Delta Stewardship Council, State of Bay-Delta Science is series of 15 publications that summarize our current scientific understanding of the Bay-Delta, and will include a report by Dr. Peter Moyle on Delta smelt.

Coequal goals

The Delta Stewardship Council was created in legislation to achieve the state mandated coequal goals for the Delta. "'Coequal goals' means the two goals of providing a more reliable water supply for California and protecting, restoring, and enhancing the Delta ecosystem. The coequal goals shall be achieved in a manner that protects and enhances the unique cultural, recreational, natural resource, and agricultural values of the Delta as an evolving place." (CA Water Code §85054)
