This project describes ongoing work by scientists in FE Ecosystem Analysis and EFS Environmental Chemistry programs to identify natal and rearing locations, reconstruct life history strategy, and evaluate juvenile performance of adult Snake River fall Chinook salmon. Due to dramatic declines in its abundance, Snake River fall Chinook salmon was listed as threatened under the Endangered Species Act. Management of Snake River fall Chinook salmon has been hindered by a great deal of uncertainty regarding key aspects of the population. In particular, the existence of an overwintering behavior in a portion of the population has complicated estimates of survival through the hydropower system. Further, differential detectability of redds has limited the ability to accurately develop run reconstructions. Effective management of Snake River fall Chinook salmon will require an understanding of the details of their early life-history, including where juveniles hatch and rear, the proportion of juveniles that exhibit the yearling strategy, when they initiate downstream migration, and estuarine residence time. In this project we investigate early life history movement and performance of Snake River fall Chinook salmon by using microchemistry and microstructure of otoliths sampled from juveniles and adults. Results from this study are intended to help inform recovery planning including future habitat restoration and conservation efforts in the Snake River Basin and Columbia River.

Otolith radius at Snake River exit
NUMBER
No
No
Active
Otolith radius was measured on the dorsal side of the otolith in the region perpendicular to the longest axis. Otolith radius at Snake River egress was measured at the point on the edge-to-core scan where 87Sr/86Sr ratio was between 0.70960 (upper and lower Snake River have a 87Sr/86Sr ratio of 0.709651 and 0.709746, respectively) and 0.70922 (the upper bound used to identify ocean entry). Units for values are microns.

Otolith radius at ocean entry
NUMBER

No
Active
Otolith radius was measured on the dorsal side of the otolith in the region perpendicular to the longest axis. Otolith radius at ocean entry was measured at the point on the edge-to-core scan where the 87Sr/86Sr ratio converged with the range of 0.70914-0.70922, which is centered on the global marine signature of 0.70918. Units for values are microns.

Otolith radius at 1st annulus
NUMBER
No
No
Active
Otolith radius was measured on the dorsal side of the otolith in the region perpendicular to the longest axis. Otolith radius was measured to the 1st annulus, which denotes the completion of an individuals first winter of growth. Units for values are microns.
NUMBER

10
Life history strategy
VARCHAR2
No
No
Active
An individual was classified as exhibiting the sub-yearling strategy if the otolith radius to the first annual mark was greater than the otolith radius at ocean entry. In other words, a fish was categorized as exhibiting a sub-yearling strategy if it was in the ocean before its first annulus formed. Alternatively, if the otolith radius to the first annual mark was less than or equal to the otolith radius at ocean entry then the fish was designated as exhibiting a yearling strategy. A sub-yearling migration strategy is when individuals migrate to the ocean a few months after their spring emergence (i.e., first feeding), while a yearling migration strategy is one in which juveniles remain in freshwater for an extended period (referred to as overwintering) prior to ocean entry the following spring.

The Northwest Fisheries Science Center facilitates backup and recovery of all data and IT components which are managed by IT Operations through the capture of static (point-in-time) backup data to physical media. Once data is captured to physical media (every 1-3 days), a duplicate is made and routinely (weekly) transported to an offsite archive facility where it is maintained throughout the data's applicable life-cycle.
