    • Growth - Production of Macroalgae for Human Consumption in the Pacific Northwest

    Metadata Updated: March 14, 2026

    This proposal will focus on the production of fresh macroalgae in a land-based system. This type of production system avoids the regulatory and permitting issues associated with water-based systems, allows precise control of the rearing environment, reduces harvesting and management costs, and reduces nutrient discharges. While macroalgae can enhance human health, specific information is needed to ensure that this product is wholesome and safe to consume. Very little information is available on the composition of farmed raised macroalgae, contaminant levels, bacterial content, and post-harvest quality issues. This research will focus on three local macroalgae: Turkish towel (Chondracanthus exasperatus), Pacific dulse (Palmaria palmata), and sea lettuce (Ulva rigida). Dulse and sea lettuce are widely eaten in Canada and Europe.

    This basic information is needed to support the development of commercial macroalgae aquaculture in the Pacific Northwest. This research will be conducted at the Sol-Sea Farm; a production aquaculture facility located at the NOAA/NMFS research station in Manchester, WA. Current work will focus on improving product quality and reducing operational costs. Growth data.
