Impact of bottom trawling on sediment biogeochemistry: a modelling approach [PDF]

Biogeosciences, 2021
Bottom trawling in shelf seas can occur more than 10 times per year for a given location. This affects the benthic metabolism, through a mortality of the macrofauna, resuspension of organic matter from the sediment, and alterations of the physical ...

Effects of bottom trawling on fish foraging and feeding. [PDF]

Proc Biol Sci, 2015
The effects of bottom trawling on benthic invertebrates include reductions of biomass, diversity and body size. These changes may negatively affect prey availability for demersal fishes, potentially leading to reduced food intake, body condition and ...

Atmospheric CO2 emissions and ocean acidification from bottom-trawling [PDF]

Frontiers in Marine Science
Trawling the seafloor can disturb carbon that took millennia to accumulate, but the fate of that carbon and its impact on climate and ecosystems remains unknown.

Reply to: Quantifying the carbon benefits of ending bottom trawling [PDF]

Nature, 2023
[Extract] In the accompanying Comment, Hiddink et al.1 challenge our estimate2 of the magnitude of seabed carbon remineralized by bottom trawling. However, we think that the conclusions by Hiddink1 are based on incorrect assumptions and that these ...

Bottom-trawling along submarine canyons impacts deep sedimentary regimes. [PDF]

Sci Rep, 2017
Many studies highlight that fish trawling activities cause seafloor erosion, but the assessment of the remobilization of surface sediments and its relocation is still not well documented.

Effects of bottom trawling and hypoxia on benthic invertebrate communities [PDF]

, 2022
Marine benthic habitats in continental shelf regions are increasingly impacted by hypoxia caused by the combination of eutrophication and climate warming.

Turning the tide on bottom trawling [PDF]

Aquatic Conservation: Marine and Freshwater Ecosystems, 2015
Trawling is universally recognized as one of the most destructive fishing methods, causing irreversible damage through scraping large tracts of bottom habitats. These habitats then suffer from declines in ecosystem functions and services, and collapses in populations of trawled species. The plethora of studies on the unsustainable impacts of commercial

Estimating sensitivity of seabed habitats to disturbance by bottom trawling based on the longevity of benthic fauna. [PDF]

Ecol Appl, 2018
Bottom fishing such as trawling and dredging may pose serious risks to the seabed and benthic habitats, calling for a quantitative assessment method to evaluate the impact and guide management to develop mitigation measures.

Contrasting particle fluxes and composition in a submarine canyon affected by natural sediment transport events and bottom trawling

Frontiers in Marine Science, 2022
Submarine canyons are important conduits of sediment and organic matter to deep-sea environments, mainly during high-energy natural events such as storms, river floods, or dense shelf water cascading, but also due to human activities such as bottom ...

Bottom trawling reduces benthic denitrification and has the potential to influence the global nitrogen cycle

Limnology and Oceanography Letters, 2020
Bottom trawling and eutrophication are large stressors that are critically coupled. Here we show, using a before‐after control‐effect design, the significant reduction in denitrification as a result of experimental bottom trawling in a shallow coastal ...
