The Mexican seas are inhabited by 111 species of sharks \citep{2015}, which represents 21.8% of those recorded worldwide \citep{s2016}. This is possible due to the great diversity of coastal and oceanic habitats on both coasts of the country. Of those species, at least 33 are of commercial interest (\citep{federacin2010} and \citep{federacin2018}) and are fished for the consumption of their meat and fins. The meat has great acceptance in the national market, whilst fins are exported to the Asian market.In Mexico there are official records of shark catches since the late 1930's. In the 1970's, shark fishing increased exponentially due to the national demand for meat and the international demand for fins, reaching 35,000 tons per year by the 1990's \citep{a1998}. After a decrease in catches in the last decade, with less than 30,000 tons per year in the current decade, catches gradually increased to 42,704 tons in 2017 \citep{sagarpa2017}.
