EYRE Peninsula's $430 million aquaculture industry can now be explored by tourists with the launch of the Seafood and Aquaculture Trail in Whyalla last week.

The Seafood Trail, created by Tourism Eyre Peninsula, links several seafood and aquaculture sites on Eyre Peninsula, offering 12 guided tours on a self-drive trail from Whyalla to Ceduna.

The launch followed a tour for Tourism Minister Jane Lomax-Smith and the media of some of the sites on the trail.

Highlights of the trail include learning about yellowtail kingfish, abalone, rock lobster, scallops, snapper, mulloway, crabs, seahorses and numerous species of shark.

On the trail tourists can view 25 to 35-kilogram mulloway and yellowtail kingfish, observe southern bluefin tuna worth as much as $5000 each, and spot the difference between prawn, rock lobster and tuna boats while viewing the largest commercial fishing fleet in the southern hemisphere.

The trail is believed to be the first of its kind in Australia, and offers a rare tourism experience for the 390,000 visitors who spend a night on Eyre Peninsula each year.

The minister launched the trail in Whyalla on Thursday, stating it would bring recognition to the region.

"The seafood industry is a key economic driver for the Eyre Peninsula, producing more than 60 per cent of the State's seafood," Dr Lomax-Smith said.

"Now visitors can discover the secrets of this dynamic industry first hand.

"Just as the Barossa tourism region is synonymous with wine, the Eyre Peninsula will become increasingly synonymous with seafood and aquaculture."

Dr Lomax-Smith said the trail would build on the region's growing reputation as a nature tourism destination.

"More visitors are seeking out the Eyre Peninsula's marine nature attractions," she said.

"Port Lincoln's Seahorse Farm is one of only four farms in the world to breed seahorses; Whyalla's coastline boasts the world's largest known cuttlefish breeding grounds; and Baird Bay provides visitors with the thrill of swimming with sea lions and dolphins."

Tourism Eyre Peninsula's marketing manager Linda Schubert said the trail was a unique showcase for the region's aquaculture industry.

"It gives tourists a very unique opportunity they won't forget," she said.

The minister also launched tourism Eyre Peninsula's new logo and slogan 'Wonders never cease,' as well as the concept for a new television advertising campaign for the region and a promotional video.
