Cooperative Shark Tagging Program It is the longest continuous shark tagging program in the world and it engages thousands of recreational and commercial fisherman. Since the program was initiated in 1962, more than 295,000 sharks of more than 50 species have been tagged.
How many sharks are tagged in the world?

How many sharks have been tagged in Australia?

Is Deep Blue still tagged?
Contrary to what has been reported, Mauricio Hoyos Padilla and his team have not tagged Deep Blue, meaning no one can follow her movements. Instead, she is frequently spotted in predictable spots year after year. The largest shark specimen that has ever lived was the Megalodon.

Does tagging fish hurt?
Speed-tagging can result in injury or mortality. For billfish, please do not remove them from the water as boating them increases their mortality significantly. Studies have proven that even when they appear to swim away fine, they die within two or three days after release.
How many great whites are tagged?
