This 10-year footprint contacted 4.4% of the Territorial Sea and EEZ seafloor area and 13% of the seafloor open to fishing, down to 1600 m. Tier 1 fisheries accounted for 87%, with hoki effort contributing 42%. The 2017 footprint covered 48 203 km2, lower than the 10-year median of 49 845 km2. The aggregated swept area from all bottom-contacting trawls for 2017 was 94 500 km2.
