A tibble with JPE data
The Juvenile Production Estimate (JPE) reported here, and implemented in the package WCR.Fisheries.xxxx (available at <NMFS internal github>), uses the "Method 2" approach described in O'Farrell et al. 2018. Staff at the NOAA Fisheries Southwest Fisheries Science Center provide the latest estimates each year for outmigration survival (Arnold Amman) and the fry-to-smolt survival rate (Michael O'Farrell).
