The tuna is caught with huge nets by large fishing boats. The boats hunt the tuna through finding dolphins since the tuna run under the dolphins. They spread out nets and to round the fish up they set off small blasts in the water. This confuses the dolphins that are in the area and they begin to draw up the nets with big rollers on the ship. As they pull the net they collect the tuna and some of the dolphins. The dolphins try to jump out of the nets, get caught in the nets and drown, or are pulled in with the tuna. Eventually , the load of tuna is pulled in and placed in the hold of the ship. Some ships pack and can the tuna right there. Others take the tuna to packing houses. In recent years there have been efforts to stop the number of dolphin deaths in the process. Whether, this has really been done or not is debatable. This why some tuna companies cite on their product that the tuna is "dolphin safe".

What predators do dolphin have?
Whales and tuna fishermen are the predators for dolphins. The dolphins follow schools of tuna so the large tuna boats look for tuna by looking for dolphins. They set huge nets to catch the tuna, but the dolphins get caught up in the nets and because they are mammals they drown in the net. Many tuna companies say they don't do this anymore, but that isn't necessarily true. You can see video on this if you want to see what happen to the dolphins.

What are some other reasons humans kill dolphins?
Many dolphins are killed in the process of tuna catching. Yellow Fin Tuna follow dolphins and the companies that catch tuna watch for the dolphins because they know that tuna is in the area. They spread miles of huge nets out to catch the tuna in, but they also get dolphins in the net. Because the dolphins are mammals they often drown in the nets, some jump over the nets, and others are pulled into the tuna boats. The tuna companies also set off bombs in the water that confuse the dolphins and this drives them into the nets as well. Today, companies state that they are "dolphin free" on their cans, but the dolphin still die.

Is tuna a predator?
Some tuna species (such as yellowfin tuna and skipjack tuna but not albacore tuna) associate with dolphins in the ocean. This helps themto avoid being eaten by sharks, which are one of their predators. Sharks are strongly attracted to tuna fish, even if the tuna fish are not injured or bleeding. However, examination of the contents of the stomachs of various sharks indicates that tuna fish have evolved to swim too fast for sharks to catch up to them and end up being eatenby sharks only occasionally.Other predators of tuna fish include orcas (killer whales), false killer whales, pilot whales, bottlenose whales, bottlenose dolphins, and marlins but the giant, filter-feeding whales and sharks can only eat small fish, which are usually not small tuna fish. Also, sperm whales occasionally eat tuna fish but like sharks, they tend to be too slow to catch up to tuna fish in most situations.However, because of man's strong appetite for tuna fish, humans are the only real possible threat to the sustainability of tuna fishing.Interestingly, blue sharks can swim as fast as tuna fish. Also, seals can swim faster than great white sharks but end up being frequently eaten by great white sharks because great white sharks wait patiently and then ambush them from deep below by surprise. All predatory sharks like to pretend that they are just harmless filter feeders when a large school of fish approaches them.
