Here’s a question: The chances of a shark being tagged must be pretty low, right? And how do they tag a shark? Is it shot with an arrow from a boat?
I asked a knowledgeable person directly involved in tagging Cape Cod's white sharks and he told me for every tagged shark, there are approx 3 untagged sharks in that area, at least
When the spotter pilot puts them on a targeted white shark they get close and put a hydrophone in the water and see if they can pick up a ping signal from a previously tagged white shark.
If no signal; they come up behind the shark and with a pole and a dart and transmitter attached, they stick the anchoring dart into the back of the shark alongside the middle of the dorsal fin, and pull the pole back out of the water.-Tom
