What We Do
The Fisheries Resources Division studies the ecology, ecosystems and fisheries of sardine, anchovy, mackerels, abalones, tunas, sharks, and many other marine species in the eastern Pacific Ocean. Our scientists:
- Collect fishery data
- Conduct stock assessments and economic analyses
- Conduct surveys on fish and invertebrate life stages using various advanced technologies
- Study their genetic structure and aquaculture potential
The science is primarily targeted to domestic and international managers of fisheries and marine resources, and results are also provided to the scientific community and the public.
Our major research areas include the following:
Advanced Survey Technologies
The Advanced Survey Technologies Program supports ecosystem-based fisheries management by surveying marine species and their ecosystems through new or innovative uses of sampling technologies.
CalCOFI (California Cooperative Oceanic Fisheries Investigations) was established in 1949. It is a quarterly at-sea survey to conduct oceanographic monitoring of marine species and the effect of environmental variability on those species found in the California Current Ecosystem. Its primary focus is on pelagic and coastal pelagic species.
Fish Population Dynamics and Modeling
The primary goal of the Fish Population Dynamics and Modeling Program is to conduct stock assessments. These assessments analyze the dynamics of exploited fish populations and provide scientific information to fishery managers regarding stock status and historical and future biomass and recruitment trends.
The Fisheries Monitoring Program collects and summarizes fisheries data such as catch weight, gear, length composition, fishing effort and location, and much more.
The Life History Program studies the age and growth, reproduction, foraging ecology, habitat, spatial distribution, and stock structure of coastal pelagic and highly migratory species in the North Pacific Ocean.
Genetics, Physiology and Aquaculture
The Genetics, Physiology, and Aquaculture Program uses cutting-edge tools to answer questions about coastal pelagic, highly migratory, and other nearshore species such as abalone, rockfish, and yellowtail.
Economics and Social Science
The Economics and Social Science Program studies the human dimension components of North Pacific fisheries.
Annie Yau, Ph.D.
Dr. Annie Yau is the Director of the Fisheries Resources Division where she provides strategic leadership and supervision and coordinates the programs. Most recently, her research has focused on life history studies of coastal pelagic and highly migratory fishes. Before coming to the Southwest Fisheries Science Center, she worked as a stock assessment scientist at the Pacific Islands Fisheries Science Center and later led their Stock Assessment Program. Annie earned her Ph.D. from the Bren School at the University of California Santa Barbara.
Dale Sweetnam is the Deputy Director of the Fisheries Resources Division where he provides oversight for the division's daily operations and supervises division administrative staff. Dale earned his M.S. in Biology from California State University, Los Angeles. Before coming to the Southwest Fisheries Science Center, he worked for the California Department of Fish and Wildlife for 22 years.
