The Monster Shark Tournament takes place in Oak Bluffs, Massachusetts every year.
It's a very controversial event because pro anglers get the chance to catch a shark, animal enthusiasts come to protest the bloody tradition, and scientists come to study sharks when they otherwise wouldn't get a chance.
It's a two day tournament where fishermen head out to sea, trying to bring home the biggest shark.
The Humane Society says it's depleting the oceans of sharks and fueling the idea that sharks are only man eaters and not integral to the ecosystem, which they are.
Integral we mean, not man eaters.
The Humane Society said:
"These tournaments make a big deal of stringing the shark up, opening its mouth and showing its teeth. It's reinforcing the idea that these are bloodthirsty predators and that the only good shark is a dead shark."
Participation is at least down in the event, with only half as many boats registering as six years ago.
C'mon people, don't kill sharks!
