Select Adult Detections

All Detections Exclude 0-Year Adult Detections Exclude 0,1-Year Adult Detections *most relevant for Chinook populations

Year is the difference in calendar year between juvenile detection and adult detection at the locations selected. For example, 0-Year are adult detections within the same calendar year as juvenile detection.

Methods

A population of fish for analysis is defined by query selections for Juvenile Detection Site, Adult Detection Site, Include/Exclude Transportation, ESU/DPS population, Rear Type, Include/Exclude Adult Detections. For this query-based population, SAR Estimates are pooled by juvenile detection year, where:
- poolSAR = adultCount / juvCount
- varSAR = (poolSAR*(1-poolSAR)) / juvCount
- se = sqrt(varSAR)
- upper95CI = poolSAR + (se * 1.96)
- lower95CI = poolSAR - (se * 1.96)
For adult detections, n-Year is the difference in calendar years between juvenile detection and adult detection at the locations selected. For example, 0-Year are adult detections within the same calendar year as juvenile detection.
We update the SAR input juvenile (fish) files for all years 2002-present on a weekly basis. The PTAGIS datasets are dynamic; release information for historical years may be updated with the primary source at any time. DART executes multiple processes to maintain synchronization with PTAGIS (primary source).
The adult detections are updated daily and up-to-date through yesterday.
