Buy from CONAPESCA online or authorised vendors., non-residents Same federal permit applies to visiting anglers and is sold online by CONAPESCA and by state tourism portals (e.g. Baja California).

FishRadar regulations are summaries for informational purposes only and are not a legal source. Mexican sport-fishing rules are set federally by CONAPESCA (NOM-017-PESC) but daily limits, reserved species and protected natural areas (ANPs, e.g. Cabo Pulmo, Revillagigedo, Banco Chinchorro) carry extra restrictions, and rules change. The overall limit is 10 organisms per angler per day, maximum 5 of one species. Always carry a valid permit when fishing from a vessel and verify current rules with CONAPESCA before fishing.
