Marine mammals and high sea fish and ocean life have long been hunted severely and are now on the brink of extinction. Dolphins are the only ocean life that have not yet been targeted by a large scale hunt. However, dolphins have from time to time been victims of tuna hunting. High sea drift fishing nets were widely used since the 1980s until they were bannded by the United Nations in early 1992. However, high sea fish and ocean life have already been threatened.

Now the hunters are turning to deep sea fishing targetting bottom dwelling fish and ocean life. Deep sea fishing have become more and more popular. Ocean life that form dense aggregations such as orange roughy have been heavily hunted because these ocean life are easy targets. Recent advances of the mapping technology of the ocean bottom have identified many areas in the ocean that have not been explored. Although, these technologies add to our knowledge of the ocean, they have also served as tools for the fishing industry. As a result, new fish and ocean life populations have been heavily hunted.

Deep sea ocean life are also threatened by pollution. Deep sea fish in the Atlantic Ocean have been found to be contaminated with pollutants from land. Several chemical pollutants have also been detected in the deep sea ocean.
