Estuary fish data - Juvenile salmon in migratory corridors of lower Columbia River estuary

Metadata Updated: April 21, 2022

Sampling juvenile salmon and associated fishes in open waters of the lower Columbia River estuary. Field work includes bi-weekly sampling during the spring outmigration (Apr-June), and monthly sampling throughout the summer and fall. We use a purse seine to sample open water habitats.

Our objectives are to document the seasonal and interannual variation in juvenile salmon immediately prior to ocean entry, with respect to abundance, size, origins (H/W), stocks, food habitats, and parasites/pathogens. We also document the larger estuarine fish community, which serves a critical role as prey for juvenile salmon predators. Abundance and size of fish caught in Columbia estuary.
