This was not a vacation trip but rather a research fishing expedition with the express goal of outfitting swordfish and other large pelagic fish in the Red Sea with satellite tags to study their movement behavior. While Red Sea coral reefs were introduced to many people by Jacques Cousteau in the 1960s, the pelagic ecosystem here remains largely unstudied. With the exception of whale sharks and manta rays, no fish have been satellite tagged in the Red Sea – effectively making it the last frontier for pelagic predator research. Furthermore, unlike other regions of the world’s oceans where deeper water is markedly cooler than surface waters, the Red Sea, from about 650 feet down to its deepest point, nearly 10,000 feet, is only 21.5ºC (about 71ºF). Thus, the thermal constraints that typically limit the depth and distribution of pelagic fish may be minimal or non-existent, potentially changing their behavior from what has been documented elsewhere.
