James A. Hobbs

Dr. Hobbs is an Environmental Program Manager for the Interagency Ecological Program’s Field Operations in the Bay-Delta Region Office of the California Department of Fish and Wildlife and is a Research Associate and Lecturer in the Department of Wildlife, Fish and Conservation Biology, University of California, Davis.

My research program integrates long-term monitoring studies with otolith growth and geochemistry to answer important fisheries resource management questions in the San Francisco Bay-Delta Estuary. I employ an interdisciplinary approach, linking population monitoring with innovative technologies such as otolith micro-chemistry and microstructure to reconstruct the migration history and growth of threatened and endangered fishes with collaborators in genetics, fish health, and population modeling to understand how climate change, habitat restoration, and resource management actions affect fish populations. At the California Department of Fish and Wildlife, I oversee long-term monitoring programs for the Interagency Ecological Program in the San Francisco Estuary.

Previous research projects include studies in coastal salt marshes and seagrass beds, pelagic estuarine habitats, and riverine habitats of the San Francisco Bay-Delta Estuary, Columbia River and Estuary, and the lower Colorado River. Species of interest include Chinook salmon, coho salmon, steelhead trout, longfin smelt, delta smelt, longjaw mudsucker, rockfish, green and white sturgeon.
