Seabed trawling and dredging (where fishing gear is towed near or along the ocean floor) can physically damage seabed (benthic) habitats and species. These fishing methods can also stir up sediment from the seabed, creating sediment plumes that can smother sensitive species. Recovery times for affected habitats and species depend on their sensitivity and the area affected by trawling or dredging. Bottom trawling is carried out on or near the seabed in both shallow and deep waters. Dredging is carried out on the seabed in shallow waters and targets marine creatures such as scallops. This measure focuses on deepwater areas (waters deeper than 200m).

The unintended catch of marine species other than the target species puts pressure on the populations of marine species by removing individuals or potentially modifying ecosystems.
This dataset relates to the "Bycatch of fish and invertebrates" measure on the Environmental Indicators, Te taiao Aotearoa website.

Sea lions and fur seals are the protected species most directly affected by fisheries in New Zealand waters, along with seabirds and dolphins. Estimating the bycatch of sea lions and fur seals indicates the pressures they face from current fishing practices.
The New Zealand sea lion Phocarctos hookeri is threatened with extinction and is classified as nationally critical. Its population is steadily falling at some breeding locations. Fisheries are one of the pressures on the species.
The Fisheries Act 1996 designates this species as protected and requires mitigation measures to reduce bycatch (Ministry for Primary Industries, 2014).This dataset relates to the "Bycatch of protected species: sea lion and fur seal" measure on the Environmental Indicators, Te taiao Aotearoa website.
