The satellite tags are carefully attached to the dorsal fins of sharks with the utmost consideration to shark health and safety. This attachment doesn’t hurt the shark are designed to eventually fall off the fin.
What happens when you tag a shark?
While on the shark, the tag collects depth, temperature, and light-level data for geolocation. On a preprogrammed date (for example, 12 months later), the tag will detach from the shark and float to the surface. Once at the surface, the tag transmits its archived data to a satellite.
Do sharks feel pain when caught?
Fish also have been observed by scientists to learn, have memory and adapt their behavior to new circumstances, arguing for their sentience. Fish are not senseless beasts, and fish feel pain, including sharks.
What is it like to tag a shark?

Sharks and rays lack a key region of the spinal dorsal horn responsible in mammals for transmitting nociceptive activity to the brain. Additionally, they lack certain fibers responsible for the intense pain induced suffering in conscious humans.
Does tagging hurt fish?
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 long do shark tags last?
SPOT tags are secured to the shark with plastic bolts and can stay on the shark for up to five years. They use radio transmission to transmit the shark’s location via satellite whenever the shark’s fin breaks the surface during a period in which a satellite is overhead.

Is it OK to tap on a fish tank?
The same noise level in the air could lead to serious hearing damage over time. And fish have it even worse: since the sound pressure is four times higher under water than it is in the air, a good portion of deaths in public aquarium can be traced back to repeated tapping on the glass.
Does it hurt animals to be tagged?
But are wild animals—similarly outfitted with tracking tags—suffering the same energetic toll? According to researchers with the US National Oceanic and Atmospheric Administration (NOAA) who used tags on fur seals in the Bering Sea, the answer is no.
