About Cascadia SEAfood

 Sustainable Ecological Aquaculture (SEA) uses the principles of ecology in the design, engineering and operation of our unique SEAfood production system - a system that meets the environmental and socio-economic needs of our current, growing population without compromising the ability of future generations from meeting their needs.   Our 'SEA Vision' represents a new and exciting approach for coastal food production - one that is Good for Nature and Good for You.

Kyuquot SEAfoods Ltd. (KSL), located on the remote and pristine northwest coast of Vancouver Island British Columbia, is the first commercially licensed SEAfarm in Canada and has been the platform for initial R&D and SEAfood System design.  KSL is now commercially licensed and is seeking investment to move forward with this initiative - please contact Dr. Stephen F. Cross, Founder & CEO, for additional information on this investment opportunity (sfcross@seavisiongroup.ca). 

The SEAfood System uses ecological design, system innovation, and best organic practices to meet the challenges of attaining environmental and socio-economic sustainability.   Technically, the SEAfood System considers three major aspects in its design: (i) nutrient, or waste removal and use; (ii) reduction of the operational carbon foot-print; and (iii) integration of certified organic management practices.


Nutrients released into the environment are a significant impact of aquatic farming today. Using Nature’s (ecological) design, the innovative SEAfood System uses an integrated, multi-species approach as the foundation of the production model – rather than the single species approach used in most operations. With only a single ‘fed’ component to the system, the organic wastes from the fish species, which would otherwise be lost to the environment, are intercepted by three groups of species that can use those wastes:  shellfish (example: scallops, oysters) which filter the water, sea cucumbers or sea urchins which vacuum the seafloor, and kelp/seaweed that remove and use the dissolved nutrients like fertilizer. As a result, and very simply, the waste nutrients from the fed fish are intercepted, extracted and then converted into a number of other high-valued SEAfood products – species that also fill these roles in nature!

Carbon Reduction is widely seen as the most critical environmental issue today. In addition to our nutrient removal design, our green SEAfood production system promotes a Sustainable Ecological Aquaculture approach using Sustainable Energy Alternatives (SEA-Power) - the latter focused on the integration of wind, solar, and ocean thermal to reduce the costly reliance on fossil fuels. Winch systems, farm accommodation, and even the work boats use SEA-Power!

Certified Organic management practices for the SEAfood system operation address many of the other environmental issues associated with aquatic farming, including food formulations, use of antibiotics and other chemicals, and animal welfare. Integrating these practices within our ecologically designed system further supports our goal of achieving a sustainable SEAfood production model.
