Physical Disturbance by Bottom Trawling Suspends Particulate Matter and Alters Biogeochemical Processes on and Near the Seafloor

Frontiers in Marine Science, 2021
Bottom trawling is known to affect benthic faunal communities but its effects on sediment suspension and seabed biogeochemistry are less well described. In addition, few studies have been carried out in the Baltic Sea, despite decades of trawling in this

Flatfish intestinal microbiota depend on various host traits, and vary with sediment type and bottom trawling effort [PDF]

Scientific Reports
The intestinal microbiota of fishes support digestion, nutrient uptake and play an important role in the immune system, development and reproduction.

Unraveling Fish Community Diversity and Structure in the Yellow Sea: Evidence from Environmental DNA Metabarcoding and Bottom Trawling [PDF]

Animals
The use of environmental DNA (eDNA) metabarcoding to analyze fish species diversity across different aquatic ecosystems is well documented. Nonetheless, there is a gap in validating eDNA metabarcoding studies on the diversity and structure of fish ...

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 ...

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.

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.

Benthic microbial biogeographic trends in the North Sea are shaped by an interplay of environmental drivers and bottom trawling effort. [PDF]

ISME Commun, 2023
Microbial composition and diversity in marine sediments are shaped by environmental, biological, and anthropogenic processes operating at different scales. However, our understanding of benthic microbial biogeography remains limited.

Ecosystem Functioning Under the Influence of Bottom-Trawling Disturbance: An Experimental Approach and Field Observations From a Continental Slope Area in the West Iberian Margin

Frontiers in Marine Science, 2020
Understanding the effects of bottom-trawling induced changes in benthic community structure, diversity and ecosystem functioning across different benthic-size components is imperative to determine the future sustainability of bottom-trawling fisheries in

Little Evidence of Benthic Community Resilience to Bottom Trawling on Seamounts After 15 Years

Frontiers in Marine Science, 2019
The resilience and recovery dynamics of deep-sea habitats impacted by bottom trawling are poorly known. This paper reports on a fishing impact recovery comparison based on four towed camera surveys over a 15-year period (2001–2015) on a group of small ...
