Benthic Indicators for Monitoring Bottom‐Trawl Fishing Impacts [PDF]
The Bulletin of the Ecological Society of AmericaThere is increasing interest in developing indicators to assess the state of benthic communities in shelf seas primarily affected by bottom trawling. Yet, many indicators have been developed in specific geographic regions making it difficult to determine their broader applicability.

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.

Biological Reviews, EarlyView.ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

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

The effect of autotrawl systems on the performance of a survey trawl [PDF]
, 2006 Three aspects of a survey bottom trawl performance—1) trawl geometry (i.e., net spread, door spread, and headrope height); 2) footrope distance off-bottom; and 3) bridle distance off-bottom—were compared among hauls by using either of two autotrawl ...

The impacts of biological invasions
Biological Reviews, EarlyView.ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Efficiency of the bottom trawl used for the Mediterranean International Trawl Survey (MEDITS) [PDF]
, 1999 The aim of the work presented in this paper was to assess the relative efficiency of the GOC 73 sampling trawl used for the Mediterranean international trawl survey programme (MEDITS) compared with that of a typical Italian commercial trawl. The latter was chosen because it is commonly used by fishermen in the central Adriatic, where the experiment was
