The Habitat, Movements, and Management of Dolphin, Coryphaena hippurus, in the Western North Atlantic, Caribbean, and Gulf of Mexico
Dolphin, Coryphaena hippurus, is a highly migratory cosmopolitan pelagic fish that is found seasonally in the Caribbean, Gulf of Mexico, and along the Atlantic coast of the United States. Dolphin are considered as one unit stock throughout the study area. This study used release-recapture data from...

Dolphin, Coryphaena hippurus, is a highly migratory cosmopolitan pelagic fish that is found seasonally in the Caribbean, Gulf of Mexico, and along the Atlantic coast of the United States.
