Aqunion

What Aqunion does

Aqunion is a South African abalone farming, processing, and export business headquartered in Hermanus, Western Cape, and operating as a subsidiary of the TerraSan Group. Founded in 1994 by marine biologist André du Plessis, the company produces the endemic Haliotis midae species using a pump-ashore flow-through tank system that supplies 24-hour fresh seawater in a controlled scientific environment. Vertically integrated operations span breeding stock, hatchery, nursery, grow-out, and processing across two primary sites—Whale Rock Farm in Hermanus (80 tonnes/year) and Romansbaai Farm in Gansbaai (200 tonnes/year)—yielding combined capacity of 280 tonnes per year, supplemented by wild-caught product and a 40-kilometre Northern Cape coastline licence for abalone ranching through subsidiary Diamond Coast Abalone. In-house abalone feed is produced by subsidiary Marifeed, and processing into live, frozen, canned, pouched, and dried formats occurs at the FSSC 22000-certified facility in Hermanus.

The company sells its products through a direct, sales-led export model to enterprise buyers in six Asian markets—Taiwan, Hong Kong, China, Japan, Singapore, and Malaysia—where it has maintained customer relationships for over 16 years. Pricing is quote-based and negotiated with the Sales Manager (Jacques du Plessis, International Commercial Director), with customisable processing, packaging, and shipping arrangements. Sustainability credentials including Global GAP accreditation, WWF Hong Kong and WWF South African Sustainable Seafood Initiative green status, and SASSI listing are central to the value proposition targeting premium food service and seafood distribution customers.

Governance is led by founder-Chairman André du Plessis, CEO Rowan Yearsly (appointed 2017, previously R&D Manager and Marifeed MD), and a team of approximately 118 employees across the two farm sites and processing facility. The company's competitive positioning rests on regulatory certifications, capital-intensive infrastructure, three decades of aquaculture domain expertise, and established Asian distribution relationships rather than on technology differentiation or rapid scale-up.

• Sea Plant ProductscoreStrategic or Co-development Partner · 1 January 2004Aqunion acquired Sea Plant Products in 2004, which became the three business units of Roman Bay Sea Farm, Marifeed (Abalone Feed Products) and SPP Canning.

Recent moves10 records

Expansion highlights4 records

Broad incumbents

• SalMar ASA: Large-scale Norwegian salmon farmer with integrated operations including breeding, feed, farming, processing, and sales. Relevant peer for vertical integration, sustainability certification, and large-scale aquaculture economics.
• Mowi ASA: World's largest Atlantic salmon farmer with vertically integrated feed, farming, and processing operations. Comparable in aquaculture scale, vertical integration, and global seafood distribution, though in a different species category.
• Clearwater Seafoods: North American premium seafood harvester and processor (now part of a Fijian-led consortium) with shellfish expertise and foodservice distribution. Comparable as a broader premium seafood exporter serving Asian and global luxury channels.
• I&J (ABALONE division): Diversified South African seafood group with an abalone farming and processing division. Overlaps with Aqunion in species, geography, and Asian export markets, but operates as part of a broader seafood portfolio.

Regional players

• Zoneco Group: Chinese aquaculture group focused on premium marine species including abalone and sea cucumber for the domestic Chinese market. Comparable in species focus and premium positioning, but serves primarily a domestic Chinese customer base rather than export.

Direct peers

• Tasmanian Abalone Farms: Australian abalone aquaculture and processing business supplying live, frozen and canned abalone, primarily to Asian markets. Directly comparable in species (greenlip/blacklip), product formats, and export-led model.
• Ocean Grown Abalone: Australian-listed abalone ranching and aquaculture operator producing premium wild-stock and farmed abalone for Asian export markets. Directly comparable to Aqunion in species focus, premium positioning, and reliance on Asian demand.
• HIK Abalone Farm (Abagold): South African abalone aquaculture group producing live, canned and frozen abalone for Asian export markets. Closest geographic and operational peer to Aqunion, with similar product formats and export orientation.
• Viking Aquaculture: South African abalone farming operation located in the Hermanus region, competing in the same premium export channels as Aqunion. Comparable in species (Haliotis midae), processing capability, and Asian market focus.

Others

• Diamond Coast Abalone (within Aqunion): Internal subsidiary referenced for completeness; operates the 40 km Northern Cape sea-ranching licence. Listed as OTHERS because it is not an independent peer but illustrates the company's own alternative production model.
