USGS actively participates in fish research in the Sacramento-San Joaquin Delta.
One example is USGS scientists are using a network of acoustic equipment to track the movements and migration of steelhead trout (Oncorhynchus mykiss) and Chinook salmon (Oncorhynchus tshawytscha) that have been fitted with radio transmitters. Data from the network are being used to model the movements and behaviors of these commercially important fish. When combined with USGS water-flow data, the tracking data aid in the understanding of how flow conditions, water-channel geometry, and turbidity are affecting salmon survival in the Bay-Delta. USGS is also studying factors that influence the movements and habitat preferences of the threatened delta smelt (Hypomesus transpacificus), which is a good indicator for estuarine health as it spends its entire life in the Delta.
