The article highlights the federal crime of capturing or commercializing the Cardiosama guanhumi, also known as the blue crab, in the municipality of Tecolutla, Veracruz, Mexico, during the species' closure period from August 15 to September 30. This period is essential for the species' life cycle, where the ovate female leaves its burrow to spawn on beaches. Violators could face up to 12 years in prison and a fine of 4,000 UMAS. The penalties are more severe if the violation occurs in protected areas, leading to a surge in the decline of the blue crab numbers. The article stresses the importance of preserving the species and allowing females to complete their cycle safely, with the involvement of various agencies and civil associations.
