This measure – the Phoenix Islands Protected Area – created the world's third-largest marine protected area and may protect deep sea corals, fish, and seamounts from bottom trawling. [46] However, the actual boundaries of this reserve and what harvest limitations may occur therein have not been detailed.
On 25 April 2019, new standards were adopted for marine protected areas that prohibit four industrial activities: oil and gas activities, mining, dumping, and bottom trawling. These standards do not retroactively void existing oil and gas licenses, or void previously approved bottom trawling activities.
Prosecution of Greenpeace for preventing bottom trawling in Marine Protected Areas [ edit ] In 2020, protesters from the environmental group Greenpeace dropped boulders on the sea bed in the Dogger Bank marine protected area, an area used by bottom trawlers, and in 2021 the group dropped more in the Offshore Brighton Marine Protected Area.
Information on each area includes which specific activities are allowed and restricted (such as diving or fishing by use of bottom trawl), as well as the protected area's boundaries. [ 4 ] The project began in 2015 [ 4 ] and, as of December 2019, ProtectedSeas has mapped 50% of global MPAs and over 2/3 of the ocean by area.
Allonby Bay off the Solway Firth, Cumbria, North East of Farnes Deep off Northumberland, and Dolphin Head, West Sussex, have been chosen as Highly Protected Marine Areas (HPMAs), which give greater protection to the marine environment, with prohibitions against activity such as dredging and trawling. The new status came into force in July 2023.
With an area of about 676 km 2 it covers shallow marine waters that are suitable for bottom trawling for demersal fish and other benthic organisms for scientific research. The area contains important habitat for juvenile fish, especially Black Rockcod and Blackfin Icefish.
A 2021 study estimated annual carbon emissions from bottom trawling at almost 1.5 billion tonnes (about 3% of the world total) and recommended that more marine protected areas be established. [14] Both the findings and the conclusions in the study have been scrutinized in more recent scientific works that do not come to the same conclusions as ...
Marine Scotland has proposed options which allow for the continuation of trawling and dredging in the MPA. [19] The South of Arran MPA will: Promote sustainable fishing such as creeling, hand diving and sea angling; Create an area protected from bottom trawling and dredging; Protect important habitats and fish nursery grounds
