Isla Cristina, located in Huelva, Spain, on the Costa de la Luz, is renowned for its centuries-old tradition in the production of high quality canned and salted fish, especially tuna, mackerel and frigate mackerel. This coastal town has a rich maritime heritage, with fishing and canning industries dating back to the 18th century, influenced by the Catalan and Levantine settlers who exploited the abundant sardine and tuna fishing. The industry experienced significant growth in the 19th century, when Ayamonte and Isla Cristina became key centers for fish processing, taking advantage of traditional techniques such as salting and canning, which date back to Phoenician and Roman times.

Unión Salazonera Isleña (USISA): A leading Andalusian company founded in 1973, USISA processes more than 12,000 tons of fish per year at its factory in Isla Cristina, focusing on canned and salted fish under brands such as Tejero, USISA and El Decano.
