FIELD ACTIVITY ADVISORY: Spring-Run Chinook Salmon Juveniles Scheduled for Release January 23 – March 24, 2019

From the San Joaquin River Restoration Program:

Approximately 225,000 brood year (BY) 2018 spring-run Chinook salmon juveniles will be released to the San Joaquin River as part of the reintroduction strategy for the San Joaquin River Restoration Program (SJRRP). The salmon will be released to the San Joaquin River in Restoration Reach 5 near State Highway 140. These BY 2018 juveniles will be released in groups ranging in size from 30,000 to 100,000. A subset of these juveniles will be tagged with acoustic transmitters and released among the larger groups. Some juveniles will also receive a photonic mark as part of a mark-recapture study

Who: California Department of Fish and Wildlife.

What: Each fish is adipose fin-clipped and fitted with a coded-wire tag to identify them as originating from the San Joaquin River. Each release group will have a unique tag code. The fish will be transported to the release site in a flatbed-mounted tank and tempered to river water temperatures onsite. The releases will occur in the evening to reduce the risk of predation and to take advantage of lower in-river temperatures that will reduce tempering duration.

Where: The fish will be released in the San Joaquin River, near the State Highway 140 crossing, and upstream of the confluence with the Merced River. The fish release site will be accessed in coordination with private landowners.
When: January 23, 2019 through March 24, 2019.
