No, magnet fishing exists in a legal gray area in Mexico, with no federal statute explicitly permitting or prohibiting it. However, activities involving public waterways or historical artifacts trigger compliance risks under the Ley Federal sobre Monumentos y Zonas Arqueológicos, Artísticos e Históricos and the Ley de Aguas Nacionales, enforced by INAH and CONAGUA respectively. Recent 2026 amendments to the Reglamento de la Ley de Aguas Nacionales now classify unauthorized object retrieval as “ilícito de uso de dominio público,” increasing penalties for violations.
Key Regulations for Magnet Fishing in Mexico
- Archaeological Heritage Protection: INAH prohibits the removal of any object over 50 years old from federal waters or protected zones, including rivers, lakes, or coastal areas. Violations carry fines up to 5,000 UMAs (≈$450,000 MXN) and potential criminal charges under Código Penal Federal Article 528.
- National Waters Usage: CONAGUA requires permits for any activity altering or extracting materials from national waters. Unauthorized magnet fishing may be deemed “uso no autorizado,” subject to immediate confiscation of equipment and assets.
- State and Municipal Bylaws: Local governments (e.g., CDMX, Jalisco) impose additional restrictions. For instance, Mexico City’s Reglamento de Espacios Públicos bans metal detecting in Chapultepec Lake without a cultural heritage permit, enforced by the Secretaría del Medio Ambiente.
Enforcement Trends: Since 2024, INAH has increased inspections in high-risk zones like the Lerma River Basin and Veracruz’s coastal lagoons, collaborating with state police to prosecute offenders. Diversion of recovered items to private collections or online sales further escalates legal exposure under money laundering statutes.
