New report says California’s ‘iconic’ native fish facing extinction in 50 years

The “Fish in Hot Water” report includes a road map for addressing the threats to California’s native fish, including restoration and protection of critical habitats, such as spring-fed rivers, flood plains and estuaries as well as river system headwaters.

On a tree-shaded bend in Dutch Bill Creek at Monte Rio, three technicians from the Sonoma County Water Agency huddled on a gravel bar to examine the day’s catch, all in the name of science and a sustained campaign to restore one of California’s most endangered fish.

Retrieving 163 coho salmon smolts, or young fish, from a wooden fish trap set in knee-deep, clear flowing water, the crew bathed the four- to six-inch salmon in a bucket of Alka-Seltzer solution, briefly numbing them for easier handling.

The technicians measured, weighed and counted the year-old, hatchery-bred fish before releasing them to continue a perilous journey to the nearby Russian River and out to the Pacific Ocean.

If the young coho, swimming mostly by night to evade predators, make it to the ocean and grow to adulthood, they may in about 18 months return to the Russian River and be counted once again before they spawn and die.

There’s a lot riding on the coho completing their short, human-assisted life cycle.Nearly half of California’s native salmon, steelhead and trout — 14 out of 31 species — are facing extinction in 50 years under current conditions, according to a scientific study released last week.

Another nine species are likely to vanish in 100 years unless steps are taken to address threats such as low water flows, pollution, urban growth, dams and degraded habitat, exacerbated by the recent drought and climate change, the 106-page report by the conservation nonprofit California Trout and the UC Davis Center for Watershed Sciences said.
