Saw it as well. I can tell you there are people are the world doing far less invasive ‘tagging’ operations, with far more ‘scientific’ intent.

These men act as cowboys–and if familiar with Japanese whaling–with the same goal, and that is not conservation of the betterment of the animal.

Great White population is unknown, no estimate, nothing. Yet, they are on red flag alert as ‘endangered’. A fish being hooked, then dragged against its will for hours, placed up on a hard deck out of water for 20 minutes,being stuck with needles, poked and prodded, having an electronic transmitter drilled and lock nutted into its fin-is beyond crude. They dont have the first guess at the damage they are doing to any particular fish captured.
