About the Study

Science-based report

The foundation of State of the Salmonids II: Fish in Hot Water is based on 32 rigorously researched, peer-reviewed biological and ecological species accounts prepared by Dr. Peter B. Moyle, Patrick J. Samuel, and Dr. Robert A. Lusardi. Each account has been externally reviewed and will be published as Salmon, Steelhead, and Trout in California: Status of Emblematic Fishes, Second Edition.

This is the second State of the Salmonids report, the first of which was published in 2008. This second edition is timely. During the writing of the first edition of the State of the Salmonids report in 2008, the commercial salmon fishery was closed due to low adult returns. Each year since then, the fishery has been restricted or constrained in some way.

At the writing of the 2017 report, the commercial salmon fishery is again closed for the season. The northern part of the state is emerging from historic drought (2012-2016), which saw significant negative impacts on salmonid populations and juvenile survival.

Further, new information, especially in the form of federal and state agency reports, and genetic and life history research that was not available before have been published, helping to paint a clearer picture of the true plight of California’s salmonid populations. While California’s climate, precipitation patterns, and trends in salmonids has changed, monitoring efforts, especially for species not listed under the Endangered Species Act, remain insufficient.

What does the loss of California's salmon, steelhead, and trout mean?
