Tagging studies, using conventional "spaghetti" tags, and more recently pop-up satellite tags, have given researchers a glimpse into blue marlin migration patterns and habits. Recaptures of tagged fish have shown multiple movements between the Caribbean Islands and Venezuela and the Bahamas, as well as between the Caribbean Saint Thomas, U.S. Virgin Islands and West Africa, and interocean travel. Most notably, a blue marlin tagged off the coast of Delaware was recovered near the island of Mauritius off the southeast coast of Africa in the Indian Ocean – a voyage of 9,254 miles. Several fish have been recaptured in the same general area where they were tagged, implying reverse migration after/over several years, but the data are insufficient to accurately determine seasonality.
