New study to understand whale shark movements around the Galapagos Islands

Under the leadership and supervision of the Galapagos National Park Service, in July, the Galapagos Migramar groups teamed up with Jonathan Green, naturalist, guide and photographer, and long term collaborator with Migramar, to begin an exciting new project focused on the world’s largest fish and its migratory patterns in the Eastern Tropical Pacific

Jonathan has amassed a wealth of information based on sightings by himself and other dive guides over the last twenty years. Although they may be found throughout the islands, whale sharks are frequently seen by divers in the northern islands of Darwin and Wolf between the months of June to November. Most sightings are of large, apparently pregnant females. It is common to see two or three whale sharks in a dive during this period. Early ultrasonic tagging work carried out by the Migramar team suggested that individual sharks did not remain long in the area, but that there was a high turnover of sharks as the season progressed.

The Galapagos National Park Service is leading this flagship effort to understand the movements of the largest fish in the world, in the waters in and around the Galapagos Islands. Funding was obtained through Conservation International by the WellMed Charitable Foundation to place up to 30 satellite tags on whale sharks throughout the 2011 season. On the first trip, 14 whale sharks were tagged, of which one was a male. As the data from the satellite tags comes through, you can follow their movements here on the Migramar site, or on the Galapagos Whale Shark Project Site. .
