well...the mexicans call mahi mahi/dolfins "grotto." I couldn't have kept that marlin even if I wanted to because our boat had run out of space after all of the other fish we caught. The black marlin was the last one and we caught him while trawling back to the harbor. Heh, all of the fish coolers and bait tanks were full of fish we had caught and on a 35 ft boat, there was no more room.
