The value of bottom trawling in Europe

Ocean & Coastal Management
Abstract Commercial bottom trawl and dredge fisheries are active across much of Europe, and their geographic footprint is extensive. More than half of seabed area is trawled every year in some parts of Europe. But these fisheries remain contentious; significant ecological and economic damages have been well documented. Yet, they remain a source

Linking species distribution models with population abundance to support adaptive fisheries management

Ecography, EarlyView.
Understanding how environmental variability structures essential fish habitat (EFH) is central to managing keystone populations in dynamic marine ecosystems. Using nearly three decades of standardized survey data (1994–2021) from the Adriatic Sea, we present the first basin‐scale, process‐based framework linking estimated habitat suitability and ...

Risk Assessment of Fishing Trawl Activities to Subsea Pipelines of Sabah and Labuan Waters

The Scientific World Journal, 2020
Introduction. Trawling is a method of catching fish in a large volume where fish nets are pulled through water using one or two boats. Bottom trawling is where the nets are pulled over on the seabed.

Organic matter contents and degradation in a highly trawled area during fresh particle inputs (Gulf of Castellammare, southwestern Mediterranean) [PDF]

Biogeosciences, 2019
Bottom trawling in the deep sea is one of the main drivers of sediment resuspension, eroding the seafloor and altering the content and composition of sedimentary organic matter (OM). The physical and biogeochemical impacts of bottom trawling were studied

Selection of indicators for assessing and managing the impacts of bottom trawling on seabed habitats [PDF]

, 2020
Bottom trawl fisheries are the most widespread source of anthropogenic physical disturbance to seabed habitats. Development of fisheries-, conservation- and ecosystem-based management strategies requires the selection of indicators of the impact of ...

Managing for resilience with ecological structure: Portfolio effects in the Laurentian Great Lakes

Frontiers in Ecology and the Environment, EarlyView.
Combined effects of global change, including land conversion, biological invasions, and overexploitation, have degraded the resilience of ecosystems and the services they provide. Here, we identify key ecological structures and processes that can be targeted by management to improve resilience at scales ranging from single species to entire landscapes.

DataSheet_1_Assessing the potential vulnerability of sedimentary carbon stores to bottom trawling disturbance within the UK EEZ.pdf [PDF]

, 2022
It is estimated that within the UK exclusive economic zone (UK EEZ), 524 Mt of organic carbon (OC) is stored within seabed sediment. However, the stability and potential vulnerability of OC in these sediments under anthropogenic stressors, such as bottom

Density Dependent Catchability In Bottom Trawl Surveys

, 1997
No abstracts are to be cited without prior reference to the author.Fish form schools, layer or patches in which the individual fish's behaviour is not independent ofits neighbours movements. On the other hand, at low densities fish may have the freedom to actas single individuals independently of what other fish are doing.

Bed‐level tools for monitoring erosion and accretion patterns: Flume validation and field testing

Limnology and Oceanography: Methods, EarlyView.
Abstract Monitoring short‐term changes in surface sediment elevation is fundamental to understanding erosion, transport, and deposition dynamics in shallow coastal environments. However, commonly used field approaches, such as horizontal markers, sediment erosion tables, subsurface sediment plates, or erosion pins, are not always cross‐validated under ...

Threats to Our Ocean Heritage: Bottom Trawling [PDF]

This open access book focuses on the destruction of our Ocean Heritage from bottom trawling. It brings together the natural and cultural sides of the marine environment to further our understanding of the importance of this heritage, how it is threatened
