Humboldt Bay Oyster Company Shellfish Farm

The Humboldt Bay Oyster Company Shellfish Farm project, managed by the Humboldt Bay Harbor, Recreation and Conservation District, involves the operation and expansion of aquaculture activities in Humboldt Bay, California. The project focuses on the production of Pacific oysters, Kumamoto oysters, and Manila clam seed. The scope of work includes the maintenance of an existing 17.8 acre farming area utilizing Floating Upwell Systems (FLUPSY), raft culture, and rack and bag culture, as well as the development of two new expansion areas totaling 13.9 acres. Additionally, the project introduces an intertidal longline culture method using tipping bags or SEAPA-type culture baskets. The project has undergone a comprehensive environmental review process under the California Environmental Quality Act (CEQA), resulting in a Notice of Determination filed on June 17, 2026, which certified that the project would not have a significant environmental effect. Key environmental considerations include the protection of eelgrass habitats, water quality, and cultural resources, with adherence to the Secretary of the Interior's Standards and Guidelines for Archaeological Documentation. Primary administration is handled by District Planner Vanessa Blodgett, with operations centered around the Woodley Island Marina and Mad River Slough.
