The goal of this project is to examine the productivity, migration timing, and survival of sockeye, coho, and pink salmon through support of essential operations at the Auke Creek Research Station in Juneau, Alaska, USA. The Auke Creek Research Station maintains a 40-plus year time series of biological and environmental data related to the timing and productivity of Pacific salmon. The weir at Auke Creek operates annually from mid-February through the end of October, with a base function of enumerating virtually 100% of outmigrating salmon fry and smolt species and returning adults. Along with basic counts, migrating fishes are subsampled for age and growth, sex, length, and genetics throughout the season. Auke Creek is the longest and most complete coho salmon time series in Southeast Alaska and is used as a regional indicator of marine survival, harvest, and productivity. Additionally, the complete enumeration of sockeye and pink salmon juveniles and returning adults provide indices of productivity that help inform science and management of those species in the Transboundary Rivers and Northern Boundary regions of the Pacific Salmon Treaty.
