. Trawl fishing during the 1970s and 1980s resulted in approximately 20,000 tons of fish being harvested. As a result, the seamounts were closed to demersal fishing (collecting fish near the bottom of the ocean, as opposed to pelagic fishing, collecting fish near the surface) beginning 1 January 1997. The original ban was supposed to be lifted 31 December 2010, but was extended until 31 December 2020. Almost a decade into the ban, a 2005
