Persistence of Biogeochemical Alterations of Deep‐Sea Sediments by Bottom Trawling

Geophysical Research Letters, 2021
Bottom trawling grounds have been expanding to deeper areas of the oceans since the mid‐XXth century, and mitigating strategies aimed to protect fish stocks, such as temporal trawling closures, have recently been implemented.

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 ...

Using large benthic macrofauna to refine and improve ecological indicators of bottom trawling disturbance

Ecological Indicators, 2020
Bottom trawling alters the abundance, diversity, size-composition, and function of benthic communities. However, the ability to detect these impacts over large spatial scales can be obscured by various complicating factors, such as community adaptation ...

Quantification and mitigation of bottom-trawling impacts on sedimentary organic carbon stocks in the North Sea [PDF]

Biogeosciences
The depletion of sedimentary organic carbon stocks by the use of bottom-contacting fishing gear and the potential climate impacts resulting from remineralization of the organic carbon to CO2 have recently been heavily debated.

Atmospheric CO2 emissions and ocean acidification from bottom-trawling

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.

Evaluating the sustainability and environmental impacts of trawling compared to other food production systems

ICES Journal of Marine Science, 2023
Mobile bottom contact gear such as trawls is widely considered to have the highest environmental impact of commonly used fishing gears, with concern about impact on benthic communities, bycatch, and carbon footprint frequently highlighted as much ...

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 ...

Quantifying the Physical Impact of Bottom Trawling Based on High-Resolution Bathymetric Data

Remote Sensing, 2022
Bottom trawling is one of the most significant anthropogenic pressures on physical seafloor integrity. The objective classification of physical impact is important to monitor ongoing fishing activities and to assess the regeneration of seafloor integrity

Impact of Piracy and Sea Robberies on Fishing Business in Nigeria: A Focus on Lagos Coastal Area [PDF]

Revista de Management Comparat International, 2019
Nigeria as a littoral state with a coastline of slightly above 800 kilometers and located in the Gulf of Guinea (GoG) region puts the government in a position that requires her to deploy resources to combat the menace of piracy and sea robbery.
