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.

Impact and distribution of bottom trawl fishing on mud-bottom communities in the Kattegat [PDF]

Marine Ecology Progress Series, 2016
The Kattegat in the inner Danish waters has been trawled for at least 80 yr, but so far only few attempts have been made to quantify the trawl effort, its spatial distribution and its potential ecological impact on the benthic fauna. GIS-analyses of VMS-data from trawling in the Kattegat by both Danish (2005-2009) and Swedish (2007-2009) vessels show ...

Quantity and biochemical composition of particulate organic matter in a highly trawled area (Thermaikos Gulf, Eastern Mediterranean Sea)

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.

Bottom trawl fishing footprints on the world’s continental shelves [PDF]

Proceedings of the National Academy of Sciences, 2018
Significance We conducted a systematic, high-resolution analysis of bottom trawl fishing footprints for 24 regions on continental shelves and slopes of five continents and New Zealand. The proportion of seabed trawled varied >200-fold among regions (from 0.4 to 80.7% of area to a depth of 1,000 m).

Relating benthic sensitivity and status to spatial distribution and intensity of trawling in the Eastern Mediterranean

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 ...

Impact of and recovery from seabed trawling in soft-bottom benthic communities under natural disturbance of summer hypoxia: A case study in subtropical Hong Kong

Frontiers in Marine Science, 2022
Bottom trawling has widespread impact on the structure and composition of benthic communities. In this study, soft-bottom macrofauna in a heavily trawled area and an adjacent marine park that has been closed to bottom trawling for more than ten years ...

Cable length optimization for trawl fuel consumption reduction [PDF]

, 2013
A numerical method for optimization of the cable lengths in trawls with respect to the ratio between the estimated trawl drag and the predicted catch efficiency is developed and applied.

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

Natural occuring oil seepages as a consequence of bottom trawling? [PDF]

, 2023
Bottom trawling is used to capture fish species that live in the seabed. The damage on the seabed trawling causes has been discussed for many years. This thesis aims to investigate whether bottom trawling for sand eels can be a cause for some of the ...

Understanding the fishers to change the fishery : why did fishers start, stay, and stop bottom trawling? [PDF]

, 2023
This research analyses the nature of human dependence on bottom trawling as a necessary precursor to constraining its impact. Bottom trawling involves dragging a weighted net along the seabed, catching and/or damaging every organism in its path.
