STOMPer Jennifer was disturbed by this violent video, which shows fishermen catching and killing bluefin tuna off the coast of Sardinia, Italy.
Warning -- this video is graphic and viewer discretion is advised.

"This shocking video shows how endangered bluefin tuna are killed - the fishermen are not able to kill them swiftly and effectively enough.
"The tuna are forced to the water surface. They crash into each other violently due to a lack of space and water until they are exhausted whilst being forced to the water surface.
"They get injured in this process and shortly afterwards, they are clubbed to death, with their blood splattering everywhere on deck.
"The sight of hundreds of terrified, dying individuals thrashing around on deck is horrific. They die a slow, painful death.
"How can humans be so cruel? Contrary to popular belief, fish have nervous systems and they do feel pain.
"Most species of bluefin tuna are endangered but they are still widely sold at Japanese restaurants here."
