Coastal Diving & Marine Services

What Coastal Diving & Marine Services does

Coastal Diving & Marine Services Ltd, trading as Coastal Shellfish, is a privately held Scottish limited company (SC341492) that harvests and directly exports premium live shellfish from the West Coast of Scotland to international B2B buyers. The company operates an owned fleet of three boats — Avocet, Loris Ellie, and Boy Harris — in the Firth of Clyde, using hand-diving and creel fishing methods to catch lobster, crab, and razor clams, which are then shipped alive from its warehouse at Unit 1 Troon Fishmarket, Harbour Road, Troon. Each shipment is accompanied by full provenance documentation identifying catch location, date, boat, and skipper, which the company positions as a traceability differentiator for premium export markets.

The business model is direct B2B export, with live shellfish sold to international seafood importers and distributors in China, Hong Kong, and Singapore under quote-based pricing. The company has been operating since 2008, is registered in Scotland, and is led by founders Michael Crowe and Michael MacCorquodale. Revenue is not publicly disclosed, no external funding or investor backing is referenced, and the firm does not publish AI, software, or digital-platform capabilities beyond its traceability record-keeping and company website.

The firm's defensibility rests on three pillars: an owned small fleet giving supply chain control, a sustainability and provenance narrative backed by involvement in local fisheries regulation bodies, and a registered Coastal Shellfish brand. Customer concentration risk is structurally high given the narrow set of export markets and the absence of disclosed named buyers or distributor diversification.

Broad incumbents

• Young's Seafood: One of the UK's largest branded seafood companies with a broad frozen and chilled portfolio including shellfish. Comparable as a UK seafood company operating in overlapping product categories, but at much larger scale and focused on retail grocery versus Coastal's live B2B export.
• Mowi: World's largest salmon producer with significant Scottish farming operations and global seafood distribution. Comparable in Scotland-based seafood operations and broad seafood distribution, but competes in farmed salmon rather than wild shellfish export.
• Bakkafrost: Large Faroese-headquartered salmon and aquaculture company with significant premium seafood exposure in Asia and elsewhere. Comparable in being a premium seafood producer targeting Asian markets, but operates in salmon rather than wild shellfish.
• Clearwater Seafoods: Globally scaled shellfish and seafood company with a strong premium shellfish portfolio (lobster, crab, clams, scallops). Comparable to Coastal Diving & Marine Services in target species and Asian export exposure, but operates at vastly greater scale and across multiple geographies.
• Whitby Seafoods: Established UK seafood processor and supplier of prepared and frozen seafood (including scampi, breaded seafood, shellfish products). Comparable as a UK-rooted seafood business in adjacent product categories, but differentiated by value-added processing rather than live wild-caught export.

Direct peers

• Loch Fyne Oysters: Long-standing West Coast Scottish shellfish producer with a heritage brand and direct retail/restaurant supply. Directly comparable to Coastal Diving & Marine Services in origin region, wild/sustainable shellfish focus, and premium positioning, though Loch Fyne skews more to oyster/mussel production rather than lobster/crab/razor clams.
• Dawnfresh Seafoods: One of Scotland's largest vertically integrated seafood businesses, covering wild catch and farmed species. Directly comparable as a Scottish-headquartered seafood producer and exporter operating in overlapping species and channels, though at materially larger scale than Coastal Diving & Marine Services.

Regional players

• Scottish Sea Farms: Scottish-headquartered salmon aquaculture company jointly owned by SalMar and Lerøy. Comparable as a Scotland-based seafood supplier with overlapping buyer relationships, but operates in salmon farming rather than wild shellfish fishing/export.
