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 ...

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 ...

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 ...

Organic biomarkers in deep-sea regions affected by bottom trawling: pigments, fatty acids, amino acids and carbohydrates in surface sediments from the La Fonera (Palamós) Canyon, NW Mediterranean Sea [PDF]
Biogeosciences, 2013 Deep-sea ecosystems are in general adapted to a limited variability of physical conditions, resulting in high vulnerability and slow recovery rates from anthropogenic perturbations such as bottom trawling.

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

Quantifying habitat preference of bottom trawling gear [PDF]
ICES Journal of Marine Science, 2020 Abstract Continental shelves around the world are subject to intensive bottom trawling. Demersal fish assemblages inhabiting these shelves account for one-fourth of landed wild marine species. Increasing spatial claims for nature protection and wind farm energy suppresses, however, the area available to fisheries.

Ecological Indicators, 2023 The ecosystem approach to fisheries management needs information of not just where bottom trawlers operate but also on their impact on the seabed, which is also highly relevant to the EU Marine Strategy Framework Directive (MSFD) Descriptor D6, seafloor ...

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 yield of fishes in chronically trawled areas.

Advances in Oceanography and Limnology, 2015 Bottom trawling represents nowadays one of the most severe anthropogenic disturbances at sea, and determines large impacts on benthic communities and processes.
