The economy is based on the huge grain-handling facilities (with a total capacity of over 337,500 tonnes), the canning and fish processing works, lambs, wool and beef, and tuna farming for the Japanese market. Home of Australia's largest commercial fishing fleet, Port Lincoln now has a thriving aquaculture industry that farms the following species: southern bluefin tuna, yellowtail kingfish, abalone, mussels, oysters, and experimentally, seahorses and spiny lobsters. Before the advent of aquaculture, the main fishing was for southern bluefin tuna. Frank Moorhouse recommended the South Australian government lend the Haldane family 20,000 pounds which they used to build a super vessel. The MFV "Tacoma" was Australia's first purpose-built tuna fishing vessel. It revolutionised the industry and began catching the fish off the coast of Port Lincoln in the early 1950s.
