Tracking the Unknown
Species like the white shark may be poorly misunderstood, but understanding the patterns of big fish can be beneficial for all marine life. OCEARCH strives to fill knowledge gaps by collecting data. They safely tag sharks with satellite and acoustic trackers. These devices, attached to the shark’s dorsal fin, transmit real-time location data accessible to the public and scientists.
Researchers have learned, shark movements are closely tied to seasonal changes. Fischer explained that the fall equinox signals the beginning of the sharks migration.
“We just passed through the fall equinox, which triggers that movement,” he said. “We already have five sharks south of Cape Cod just since the equinox. They feel it. The equinoxes and solstices drive their lives.”
Expanding knowledge in the Atlantic
Years of tracking have significantly advanced scientists’ knowledge of great white sharks.
According to Fischer, “We now have, off Atlantic Canada and the U.S. East Coast, the most comprehensive understanding of our white shark population.”
Mature males like Contender are particularly valuable, providing key insights into their behaviour, migration patterns, and overall health.
