Scientists working on the recovery of endangered coho salmon in northern California appreciate success even if it comes in small doses. Field biologists from the California Department of Fish and Game recently reported that the fall of 2010 produced the largest number of returning coho in tributaries of the Russian River in more than a decade.

Prior to the launch of a recovery program in 2001, the number of returning adult coho salmon averaged less than four per year. These low numbers were the catalyst for the Russian River Coho Salmon Captive Broodstock Program, a recovery effort in which offspring from hatchery-reared adults are released into the river system. This past season, biologists estimate that more than 190 adult coho returned to the Russian River system, beginning with early storms in October and peaking in December. Click here to read more…
