Located in the central-western part of the country, Lake Chapala is Mexico’s largest lake, and one of the many fishing villages bordering the lake is Petatán, with a population of only 423 inhabitants. However, what makes Petatán special is that most fish caught in Lake Chapala—tilapia and carp—as well as other water bodies in the region is processed here. There are no official statistics for how much fish is filleted and packed in ice every day, but Petatán houses the second largest fish processing industry in the region. The fish filleted here goes to El Mercado del Mar, the second largest fish market in the country, from where it is distributed to restaurants, smaller markets and other parts of the country.
