Mexico has selected nine fish species and reserved them exclusively for the activity of sport fishing practiced in the area located within the first 50 nautical miles measured from the sea-shore. Six of these species are commonly known as “Picudos” (Billfish), these include 4 species of Marlin, Sailfish and Swordfish, in addition to Tarpon fish, Roosterfish and Dolphin fish (also known as Mahi-Mahi or Dorado).
Sport fishing permits strictly prohibit any commercial fishing activity or making any monetary gain from their use. On-board filleting is also forbidden and catches must be destined for personal consumption or taxidermy mounts.
It is compulsory for every sport fisherman to have a license to practice the activity, according to Mexican Federal Duty Law.
Sport fishermen must abide by Federal dispositions regarding minimum sizes, fishing bans and may only use fishing poles, reels, lines with hooks and with or without bait or lures.
Sport fishing service providers must keep and present when required a fishing log (which is available at the CONAPESCA web site).
Catches are limited to five fish daily per sport fisherman in freshwaters and ten fish in saltwater, with the following quota limits per species:
Not more than five fish of any one species.
Regarding Marlins, Sailfish, Swordfish and Shark, the maximum limit for each sport fisherman will be of one specimen per day; any catch of these species is to be considered equivalent to five specimens of any other.
In case of Tarpon fish, Dolphin fish (Dorado or Mahi-Mahi) or Roosterfish, the maximum limit allowed will be two specimens, and will be also equivalent to five of any other species.
