I want you all to know that currently there is a lobster fishing ban in Mexico. This varies by region bt Costa Mujeres is not able to et lobster. Riviera Maya may have some frozen lobster left.
Lobster in Costa Mujeres/Cancun: This falls in Zone V and therefore it is forbidden to catch lobster from March 1 to June 30. Costa Mujeres had some frozen but the suppliers no longer have it due to the current fishing ban. (Per management)
