But it also damages the seafloor, releasing carbon and killing non-target marine life &#8211; like coral, fur seals, dolphins and seabirds.<\/p>\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Stop Bottom Trawling in New Zealand\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/fWWwJBdSXmk?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><figcaption class=\"wp-element-caption\"><em>Bottom trawling by NZ fisheries<\/em><\/figcaption><\/figure>\n\n<h2 class=\"wp-block-heading\" id=\"BottomTrawlingSpecies\"><strong>What are bottom trawlers trying to catch?<\/strong><\/h2>\n\n<p>New Zealand fishing companies are mostly trying to catch orange roughy and oreo. These deepwater fish are often found around seamounts or underwater mountains. Most of what&#8217;s trawled is then exported to China or the United States.<br><br><a href=\"https:\/\/www.greenpeace.org\/aotearoa\/press-release\/projection-calls-for-nz-to-stop-destructive-bottom-trawling\/\">Orange roughy are in decline<\/a> in many fishing areas, and overfishing from bottom trawling has caused numbers of the deep sea fish to collapse in the past.<\/p>\n\n<h2 class=\"wp-block-heading\" id=\"Where-Bottom-Trawl\"><strong>Where does New Zealand bottom trawl?<\/strong><\/h2>\n\n<p>New Zealand commercial fishing companies bottom trawl both within New Zealand waters, <a href=\"https:\/\/newsroom.co.nz\/2023\/04\/09\/hauraki-gulf-marine-park-no-place-for-trawling\/\">including in the Hauraki Gulf<\/a>, and in international ones.<\/p>\n\n<p>In fact, New Zealand is one of only seven countries still using this fishing method in international waters. It&#8217;s also the <a href=\"https:\/\/www.greenpeace.org\/aotearoa\/press-release\/projection-calls-for-nz-to-stop-destructive-bottom-trawling\/\">only country still bottom trawling in the South Pacific<\/a> high seas.<\/p>\n\n<h2 class=\"wp-block-heading\" id=\"BottomTrawlingDestructive\"><strong>Why is bottom trawling destructive?<\/strong><\/h2>\n\n<p>Bottom trawling is considered one of the most destructive fishing methods because it is highly indiscriminate in what it catches. The heavy, weighted nets destroy the seafloor.<\/p>\n\n<p>Dolphins, turtles, seals, seabirds and other marine life like coral also get caught and killed in bottom trawl nets, which means the impacts of bottom trawling are widespread.<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-bottom-trawling-bycatch-is-large\">Bottom trawling bycatch is large<\/h3>\n\n<p>Bottom trawling works by dragging a large weighted net across the ocean floor. These trawl nets catch both the target fish, and everything else in the way.<\/p>\n\n<p>Many other species are also caught and destroyed as \u2018bycatch\u2019. This includes coral, dolphins, turtles, sharks and seabirds like the antipodean albatross.<br><br><a href=\"https:\/\/www.mpi.govt.nz\/fishing-aquaculture\/sustainable-fisheries\/managing-the-impact-of-fishing-on-protected-species\/seabirds-and-protected-marine-species-caught-by-commercial-fishers\/\">Latest figures<\/a> show that 522 seabirds (including albatross) and 152 mammals (including fur seals and dolphins) <a href=\"https:\/\/www.greenpeace.org\/aotearoa\/press-release\/the-cost-of-trawling-3000kg-dead-coral-in-one-year\/\">were killed by bottom trawling over a 12 month period<\/a>.<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-bottom-trawling-destroys-coral-reefs\">Bottom trawling destroys coral reefs<\/h3>\n\n<p>Coral forests are not just important in their own right, but also for the habitats they create. Other creatures find a home within their branches making these areas important, vibrant ecosystems. So when bottom trawling nets are dragged repeatedly over seamounts, they destroy not only the coral forests but also the whole community that formed around them.<br><br>Deep sea coral is often slow going and fragile making it vulnerable to bottom trawling. Tonnes of coral are being pulled up in nets every year.<\/p>\n\n<p>A <a href=\"https:\/\/www.doc.govt.nz\/globalassets\/documents\/conservation\/marine-and-coastal\/marine-conservation-services\/reports\/202122-annual-plan\/int2021-02-characterisation-of-protected-coral-interactions-final-report.pdf\">report released in 2023 <\/a>showed New Zealand commercial fishers pulled up nearly <a href=\"https:\/\/www.greenpeace.org\/aotearoa\/press-release\/bottom-trawling-destroyed-coral-report-21-june-2023\/\">200 tonnes of coral over a 13 year period<\/a>. Bottom trawling was responsible for nearly all of this (99%) coral \u201cbycatch\u201d. But that is likely to be the \u201ctip of the iceberg\u201d as destroyed coral is also left on the seafloor.<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-bottom-trawling-is-like-deforestation\">Bottom trawling is like deforestation<\/h3>\n\n<p>Think about a forest on land. The ancient trees are worth saving alone. But when you bulldoze a forest, you also lose the whole ecosystem of smaller plants and animals that call it home.<\/p>\n\n<p>We\u2019ve all felt moved watching the video of a lone orangutan clinging to the last tree as bulldozers level its forest home. But this is happening in our oceans too. Sadly what happens in the deep is so out of sight, it\u2019s simply out of mind for many.<\/p>\n\n<figure class=\"wp-block-image size-large caption-style-medium caption-alignment-center\"><img decoding=\"async\" src=\"https:\/\/www.greenpeace.org\/static\/planet4-aotearoa-stateless\/2020\/04\/d2650e27-gp0stu60j_web_size.jpg\" alt=\"Black seabream, yellow amberkacks, Mount Vema seamount, Seamount biodiversity, Greenpeace, Greenpeace pole to pole, Bottom trawling on seamounts\" class=\"wp-image-8293\"\/><figcaption class=\"wp-element-caption\"><em>Shoals of black seabream and yellowtail amberjacks circle above one of Mount Vema\u2019s summits.<br>Seamounts are known to be unique ecosystems.<\/em><\/figcaption><\/figure>\n\n<h3 class=\"wp-block-heading\" id=\"h-bottom-trawling-impacts-many-many-species\">Bottom trawling impacts many, many species<\/h3>\n\n<p>Coral forests, coined the \u2018kauri of the ocean,\u2019 act as nurseries for many juvenile fish species and other invertebrates. They are often found growing on seamounts, or underwater mountains. These marine environments are vital for the fish, starfish, crabs, sea urchins, brittle stars, mollusks, sponges, and worms that live there.<\/p>\n\n<p><a href=\"https:\/\/www.greenpeace.org\/aotearoa\/map-seamounts-of-aotearoa\/\">Seamounts <\/a>are also thought to be vital stop-off points for migratory species, like whales. Research suggests some species of whales even use <a href=\"https:\/\/royalsocietypublishing.org\/doi\/10.1098\/rsos.150489\">seamounts for navigation<\/a> and to stop and feed during their long journeys.<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-bottom-trawling-targets-diverse-and-delicate-areas\">Bottom trawling targets diverse and delicate areas<\/h3>\n\n<p>Trawlers target seamounts precisely because they are hot spots for fish and other marine life. Key commercial fish species like orange roughy often hang out on seamounts, so commercial fishers trawl over them to get their catch.<\/p>\n\n<p>Seamounts <a href=\"https:\/\/www.greenpeace.org\/aotearoa\/story\/what-are-seamounts-and-why-do-they-matter-to-the-ocean\/\">are enormous mountains under the sea<\/a>.

And that means protecting them from devastating activities like bottom trawling.<\/p>\n\n<p>If we want to prevent more species from going extinct, or joining the growing <a href=\"https:\/\/www.iucnredlist.org\/\">IUCN red list<\/a> we must take decisive action.

Bottom trawling occurs in many significant marine areas around the country. This includes on seamounts and other vulnerable areas like the Hauraki Gulf, where bottom trawling has contributed to pushing this unique ecosystem to the brink of collapse.&nbsp;<\/p>\n\n<p>New Zealand owned fishing companies, such as Talley\u2019s and Sanford trawl internationally and in New Zealand waters.
