California has long been home to a rich array of native freshwater fish, including some species found nowhere else in the world. There is the Paiute sculpin that favors cold waters moving over the shallow gravel of a mountain streambed, the voraciously predatory Sacramento pikeminnow that can be found in deep river pools, and the tidewater goby that prefers the brackish waters of estuaries. Of course, there are also well-known fish such as salmon and steelhead trout that migrate every year from the Pacific Ocean to the state's coastal rivers.

Grantham says the team's findings mean most native fishes will require active management outside of protected areas. He hopes the research will provides the foundation for a statewide plan to guide conservation and management of the state's native freshwater biodiversity in an efficient and cost-effective manner.
