catch prohibited from Feb 1 to Mar 3101/02 to 31/03
In Mexico, catching all grouper species, a group in which NOM-065 includes the badejo-garopa (cuna garopa or mero gallina), is banned from Feb 1 to Mar 31 in federal waters of the Gulf of Mexico off Tabasco, Campeche, Yucatán and Quintana Roo, up to the border with Belize. Bottom longlines are also banned in that period. The agreement does not mention sport fishing: confirm with Conapesca whether it applies to your type of fishing.

Mexico: up to 3 kg of grouper per angler per day (household consumption)
3 kg per angler per day
In federal waters of the Gulf of Mexico and the Caribbean, NOM-065 allows, for household-consumption fishing, at most 3 kg per angler per day of any grouper species or associated species, such as the badejo-garopa. The fish is for the angler's and family's own consumption only, may not be sold, and only equipment that one person can operate alone is allowed. Sport fishing has its own rule (NOM-017-PESC-1994), which we did not check.
