Salted fish are characteristic products of the North Aegean Sea islands, and especially of the Province of Lesvos. Famous around the world are the Kalloni sardines. In Lesvos and Lemnos there are small industries for the processing and standardization of fishes for long period of time. Fish are cought on a daily basis by small island boats (psarokaeka) and the processing that follow is based on experience, which is inherited from generation to generation, enriched with the modernization of the proper machinery. Fish that are processed, are sardines, mackerels and tuna-fish, in a traditional way with pure natural sea-salt. The factors which give a superiority to the Lesvian salted fishes is the high quality of the fish and their natural environment especially in the two gulfs of Lesvos island (Gera's & Kalloni's).
