Invertebrate Management Project: Sea Urchin Work Products

Much of the research that the Invertebrate Management Team completes to aid in the management of important commercial and recreational marine invertebrate fisheries is documented in the form of technical reports, data summaries, and scientific publications, including the Fish and Game Quarterly. Invertebrate Management Team staff also engage and educate the public through Outdoor California articles, flyers, educational brochures and other venues. The following links provide access to many of CDFW's sea urchin work products and publications that fall within the realm of fishery-dependent and fishery-independent research, and educational outreach.
