Deep sea
Deep sea fishing is becoming more accessible with technological advances and more attractive as global fish stocks decline. Most commercial fish come from the shallow seas of the continental shelves or the surface water of the open oceans. Deep sea fishing involves fishing below 1,000 feet. Deep sea regulation inside each country's 200 mile limit is in its infancy, and it is non-existent in many places. One deep sea fish, blue whiting, has a sustainable catch of 1,000,000 tons a year. Norway alone catches 880,000 tons a year.
