Port Lincoln is synonymous with premium ocean produce. Situated on the lower Eyre Peninsula, the coastal city supports an enduring maritime industry that balances generational knowledge with modern environmental stewardship. The cold, clean waters of Boston Bay and the Spencer Gulf provide ideal conditions for cultivating some of the most sought-after seafood in the world.
Mastering sustainable aquaculture
At the forefront of this sector are local suppliers who have transformed traditional fishing into sophisticated, sustainable aquaculture operations. Eyre Peninsula Seafoods stands out as a primary example of this ongoing evolution. Founded by industry pioneers Andrew Puglisi and Mark Andrews, the business harvests native blue mussels all year round. The company produces more than 2300 tonnes of shellfish annually, relying on strict Best Aquaculture Practices certification to guide its operations.
Their suspended longline farming techniques are designed to protect the surrounding marine ecosystem. The mussels act as natural water filters, requiring no supplementary feed and leaving a minimal environmental footprint. Innovative vacuum packaging then seals in the ocean flavour, extending shelf life and ensuring the product remains fresh when it reaches domestic and international dining tables.
Championing offshore ranching
Beyond shellfish, Port Lincoln is globally recognised for its premium Southern Bluefin Tuna. Family-owned enterprises like the Stehr Group have championed the offshore ranching model, moving the entire industry toward a highly sustainable future. Established more than 50 years ago by Hagen Stehr and now directed by his son Marcus Stehr, the company catches wild tuna using the selective purse seine method. Crews carefully transfer the fish to offshore pontoons for controlled growth, feeding, and daily monitoring over a period of up to six months.
According to the Marine Stewardship Council, the Australian Southern Bluefin Tuna purse seine fishery operates as a certified sustainable operation. This official certification marks a significant achievement in long-term stock recovery, rigorous quota enforcement, and responsible fisheries management.
Supporting the coastal economy
These marine operations function as foundational pillars of the regional economy. The seafood sector in Port Lincoln supports local maritime academies, creates lasting regional employment, and supplies hospitality venues across the country. Major suppliers invest millions of dollars into regional infrastructure, supply chain logistics, and local community initiatives. They also prioritise transparent traceability, ensuring that chefs and consumers can track every harvest directly from the dockside to the final dish.
By investing in clean water initiatives and strict regulatory compliance, Port Lincoln producers ensure the longevity of their specialised trade. Their ongoing commitment to exceptional quality guarantees that the region will continue to lead the global seafood market. Diners who enjoy a bowl of local mussels or a piece of premium tuna are experiencing the direct result of a community dedicated to its coastal heritage.
