Resilient California Fishes: Sacramento Sucker

A Conservation Footprint for Multiple Species of Wildlife in California Rice
By John M. Eadie, Daniel S. Karp, and Andrew L. Rypel Picture a farm. Only one crop type is grown over a vast field stretching to the horizon.

By Peter B. Moyle The Challenge We are living in the Anthropocene, an era being defined by global mass extinctions caused by humanity.

Conserving fish, conserving water, conserving California

To me, these native fishes define the unique regions of the California mosaic. Southern steelhead persist in the face of extreme urbanization in southern California. Various pupfish species thrive in…
