FYI people... just so that you know... what they serve at Mariscos German isn't exactly Smoked Marlin its actually Smoked Ahi... I've had both in Cabo, as well as frequently cooking with them in Hawaii... the red hue is a dead ringer for Smoked Ahi and is actually its natural color. Marlin actually gets quite greyish brown.
I have confirmed that in Mexico... it is common to label Ahi as Marlin because Ahi is actually significantly cheaper... so they wholesalers & markets fetch a better price. Also, other types of big "swordfish-esque" fishes usually get labeled as Marlin.
Its actually fortunate that most places serve Smoked Ahi instead because it has much lower levels of mercury & other heavy metal contaminants.
