Nearly every time I have fished in mexico,I was told that the lodge or someone was providing me with the necessary license. However I have never seen it. However when I fished offshore Ixtapa, we were strongly encouraged by the captain to get a license. However it was extremely difficult. We would have had to be on the right corner at the right time when the government guy came by. There was no place to go. We could have asked the captain to get the license, but they wer not all that anxious to help and pleaded ignorant of cost, etc. Needless to say we didn't get one and didn't get checked. Apparently the fines are pretty severe.
