Deep-sea fisheries exist throughout the oceans, but fish at these depths have characteristics that make them highly vulnerable to commercial fishing. A group of scientists analyzed data on deep-sea fish populations and biology, along with economic drivers and international regulation, and concluded that most deep-sea fisheries are unsustainable, especially on the high seas.
