Both PSAT and conventional tags have provided incredible advances in our knowledge of movements and migrations of blue marlin, and anatomy and physiology studies tell us how they do it. Worldwide, cyclic movement patterns occur in sync with migratory food sources or to prime feeding areas, followed by travel to spawning areas in which prey items may be relatively scarce. It's interesting that some individuals make large-scale movements, while others might hang around a given area for extended periods of time. One blue tagged off of Delaware was recaptured in the Indian Ocean, near Mauritius. Another moved from the Tasman Sea off southeastern Australia to the Indian Ocean off southeastern India. Another individual tagged near Puerto Rico had its PSAT pop up 120 days later, 4,776 miles away, offshore of Angola, Africa. Others swam from Hawaii to Mexico, and to French Polynesia. Some blues circulate around the Western Pacific, and others between the Coral Sea off of northeastern Australia to the South Pacific islands. And then there are the homebodies, PSAT-tagged blue marlin that stayed in limited areas, such as Hawaii, the Gulf of Mexico, the Kuroshio Current system and the Caribbean Basin, for extended time periods.
