About Ocean Harvest Technology
Pioneering seaweed-based solutions for sustainable animal nutrition
The Company
Ocean Harvest Technology is a global leader in seaweed-based nutrition for animal health and performance.
Founded on the belief that the ocean holds the key to a more sustainable feed industry, we have dedicated over 20 years to researching, developing and commercialising functional seaweed blends that deliver measurable benefits to animals, producers and the planet.
Operating globally with teams in the United Kingdom, Europe and Vietnam, we combine marine science, animal nutrition expertise and responsible production to create feed ingredients that are natural, consistent and performance-driven.
Our proprietary product line, OceanFeed™, is built on a unique blend of green, red and brown seaweeds — formulated to support digestive health, feed efficiency and resilience in multiple species, including poultry, swine, ruminants, aquaculture, pets and horses.
Healthier Animals. Healthier Humans. Healthier Planet.
Our Mission
Our mission is to ensure that Ocean Harvest Technology remains at the forefront of the global shift toward sustainable animal nutrition — as the world's leading supplier of blended seaweed feed ingredients.
We are committed to:

Future Sustainability
Building a sustainable future where profitability and environmental responsibility unite.
For us, sustainability and profitability go hand in hand — one strengthens the other.
The Global Challenges
The feed and livestock industries face growing pressure to produce more animal protein using fewer resources — and to do so responsibly.
We ask the questions that matter:
How can animal production become more sustainable as the global population grows?
How can welfare be promoted while reducing antibiotic use and antimicrobial resistance?
How can marine ecosystems be restored through responsible seaweed management?
How can we protect limited resources such as arable land and freshwater?
These challenges define the purpose behind everything we do at Ocean Harvest Technology.
Our Solution
Ocean Harvest Technology holds two UK patents for its pioneering work with blended seaweeds in animal nutrition.
Our OceanFeed™ range is designed to help the feed and livestock industries progress toward more sustainable, efficient and responsible production systems.
We support animal health and resilience — improving nutrient utilisation and overall performance.
We contribute to responsible antibiotic reduction strategies, by supporting natural gut balance and immune function.
We use mainly invasive seaweed species, helping to restore marine ecosystems and biodiversity.
OceanFeed™ doesn't require arable land or freshwater, relieving pressure on agricultural resources.
By integrating OceanFeed™ into modern feeding programs, producers can improve technical performance and sustainability metrics simultaneously — achieving measurable gains in both profitability and ESG performance.
