What Atlantic Mariculture does

Atlantic Mariculture Ltd. (AML) is a UK private aquatechnology company that operates multi-trophic aquaculture (IMTA) systems combining seaweed and shellfish cultivation on the West Coast of Scotland. The company's 15-hectare flagship farm at Oronsay East in Loch Sunart (site licence MS-00010108) has been operational since 2021 with a per-season production capacity of approximately 100 tonnes of kelp, and a second farm at Kentra is scheduled for January 2025 deployment to add capacity for an additional 200 tonnes of kelp and 50,000 oysters. All production sits alongside the world-class Ardtoe Marine Laboratory, which houses the company's R&D activities, a seaweed hatchery and seed bank, and product development operations.

The core product portfolio centres on Liquid Kelp™, a Soil Association-certified organic liquid fertiliser produced from cultivated Scottish sugar kelp (Saccharina latissima) using natural fermentation and cold-pressing techniques without heat or chemical extraction, sold in 1L, 5L, 20L, and 1,000L IBC volumes. AML also supplies raw and semi-processed sugar kelp and winged kelp (Alaria esculenta) biomass for use in food, pharmaceuticals, bioplastics, animal feed, and biofuel applications, plus oysters from its IMTA operations. Underlying technology includes state-of-the-art modular farm systems with interlocking components designed for both inshore and offshore deployment, sensor-based water-quality and growth monitoring, real-time data analytics with yield prediction, and a proprietary seaweed hatchery and seed bank for strain traceability. Service offerings span turnkey farm design, installation, regulatory-compliance consultancy, and research partnerships with bodies including the James Hutton Institute, SRUC, the Scottish Seaweed Industry Association, IBiolc, Hortimare, Algapelago, and Buccleuch Estates.

Atlantic Mariculture generates revenue across four streams: direct sales of Liquid Kelp™ fertiliser products, raw/semi-processed seaweed biomass sales, oyster cultivation, and enterprise consultancy and farm-design services. The distribution model is predominantly direct, with enquiry-based ordering, multiple volume SKUs for bulk and smaller buyers, and a free preliminary consultation pathway as lead generation. Target customers span farming and agriculture, horticulture, plant nurseries, viticulture, golf-course turf management, home gardeners, CBPM growers, and aquaculture operators seeking turnkey farm solutions. AML is positioned as the operator of the largest inshore seaweed farm currently on the West Coast of Scotland, with an explicit roadmap to scale to thousands of tonnes of biomass annually by 2029.
