Yes, they do. That is why Tuna ranchers must keep sharks out of their holding pens. Tuna "ranchers" keep juvenile tuna in enormous, very deep nets (pens) which supported by buoys and kept just a few miles off land. The young tuna are trapped in "seine" type nets, moved to the deep nets, fed ( like "feedlots"), and held until reach the desired weight after several months. The tuna are usually fed sardines or other small fish, twice daily, until they are harvested ("killed"). Shark must be kept out of the nets because they will eat the tuna or damage the tuna, which can be worth as much as $173,000 at the fish auctions in Japan. The ranchers are working very hard to "grow" the tuna, like cattle or pigs. Tuna are practically worth their weight in gold.
