What Ocean Harvest Technology does

Ocean Harvest Technology is an Ireland-based ag-tech company, founded in 2005 and publicly listed on the London Stock Exchange (LSE: OHT), that develops and commercializes proprietary seaweed-based prebiotic feed additives for animal nutrition under the OceanFeed™ brand. Its core technology is a patented multi-species macroalgae blend combining green, red, and brown seaweeds, processed without solvents or extraction chemicals to preserve the full natural matrix of bioactives, including sulfated polysaccharides (ulvan, fucoidan), phlorotannins, and carotenoids (fucoxanthin, astaxanthin). The portfolio addresses gut health, immune modulation, antioxidant support, and feed efficiency across six species-specific product lines: Poultry, Swine, Aqua (fish, shrimp, salmon), Ruminants, Equine, and Pet.

The company manufactures at a GMP+ certified facility in southern Vietnam, where products are blended and standardized in meal, crumble, pellet, and powder formats, and distributes globally through direct B2B sales and regional distributor partnerships. Logistics are organized around three hubs: large shipments (10+ tons) ship directly ExW or CIF from Vietnam with a roughly two-week lead time, while smaller European orders are fulfilled from a Netherlands hub and smaller US orders from a New Hampton, Iowa hub, both typically on ExW or DAP terms with two-working-day dispatch readiness. Pricing is reviewed quarterly based on raw material and logistics costs.

Ocean Harvest Technology targets feed manufacturers, integrators, feed mills, on-farm mixers, animal breeders, livestock producers, aquaculture operators, equine professionals, and pet nutrition experts. The company is differentiated by 20 years of domain specialization in seaweed-for-animal-nutrition, full supply-chain traceability through certified local harvesters, and compliance with GMP+ Feed Safety Assurance, BETA NOPS, and SA8000 certifications, which are particularly valued in equine and pet channels. Revenue is generated through one-time product sales of feed ingredients rather than subscriptions or licensing, and specific financial figures are not publicly disclosed.

Core offering

Ocean Harvest Technology develops and manufactures the OceanFeed™ product line — proprietary whole-seaweed blend feed additives combining green, red, and brown macroalgae species containing prebiotic fibers and marine bioactives (sulfated polysaccharides, phlorotannins, carotenoids). Products are sold in meal, crumble, pellet, and powder formats across six species-specific formulations (Poultry, Swine, Aqua, Ruminants, Equine, Pet) to feed manufacturers, integrators, livestock producers, aquaculture operations, equine and pet nutrition professionals, and animal nutrition distributors worldwide.

Product overview

Ocean Harvest Technology offers the OceanFeed™ product line — a portfolio of species-specific seaweed-based feed additives built on a proprietary blend of sustainably harvested macroalgae (green, red, and brown seaweeds). The product line includes six core formulations: OceanFeed™ Poultry, OceanFeed™ Swine (covering piglets and sows), OceanFeed™ Aqua (for fish, shrimp, and salmon), OceanFeed™ Ruminants (for dairy cows and beef cattle), OceanFeed™ Equine, and OceanFeed™ Pet. All products share a common foundation of whole-seaweed composition enriched with prebiotic fibers and marine bioactive compounds (sulfated polysaccharides, phlorotannins, carotenoids) and are available in meal, crumble, pellet, and powder forms. The portfolio targets feed efficiency, gut health, immune resilience, and sustainable animal production across livestock, aquaculture, equine, and companion animal sectors.
