Abstract:
Widespread bottom trawling in British waters has traditionally been dated from the last decades of the 18th century, and its early heartland has most commonly been identified as the Torbay area of Devon. This article shows that, in fact, by the time Torbay became known as a centre for the industry, bottom trawling was already well-known and relatively widespread around much of England and Wales, as well as large parts of Eastern and Southern Ireland. Following on from an earlier contribution in this journal, it also demonstrates that bottom trawling’s unbroken history, going back to at least t

Abstract:
Abstract Two alternative stimulation techniques to reduce mortality in benthic megafauna were tested relative to standard tickler chain beam trawling: longitudinal electrodes (pulse trawl) and longitudinal chains. Longitudinal chains caused higher mortality than pulse trawling in 3 species. Standard trawling gave higher mortality in Echinocardium cordatum than pulse trawling. Between longitudinal chain and standard trawling were no significant differences. This trend in decreasing mortality from longitudinal, to standard and then pulse trawling was confirmed by a similar decline in: i) numbers

Abstract:
Abstract Fisheries using bottom trawls are the most widespread source of anthropogenic physical disturbance to seafloor habitats. To mitigate such disturbances, the development of fisheries-, conservation-, and ecosystem-based management strategies requires the assessment of the impact of bottom trawling on the state of benthic biota. We explore a quantitative and mechanistic framework to assess trawling impact. Pressure and impact indicators that provide a continuous pressure–response curve are estimated at a spatial resolution of 1 × 1 min latitude and longitude (∼2 km2) using three methods:

Abstract:
Nematodes, because of their small size and short life cycles, are thought to be less affected by direct trawling mortality compared with the larger macrofauna. However, nematodes may still be indirectly affected by the physical disturbance of trawling through changing sediment characteristics and food web structure. We determined whether nematode communities on two muddy fishing grounds located in the North Sea and Irish Sea were affected by chronic otter-trawl disturbance and quantified these effects. Nematode abundance, production, and genus richness declined in response to trawling within b

The use of trawling as a fishing tool has long been known to have a very bad impact on the environment and creates social conflict in fishing communities. Likewise, on the North-East coast of Aceh there are still fishermen who use trawlers as fishing gear. On the other hand, the use of trawling is very damaging to the environment and causes social conflicts for fishermen. The cessation of trawling operations also has an economic and social impact on fishermen who have been using trawling for their livelihood.

Most experimental studies on the effects of trawling on the benthos use remote sampling techniques and are conducted in recently trawled areas. Thus it is difficult to determine the effects of trawling on previously unfished areas, and the fates of individual animals cannot be followed. In this study, I follow the fates of individuals of several sessile taxa when exposed to experimental trawling in areas that have not been trawled for some 15–20 years. Although there was a significant trawling by location effect for all multivariate analyses and most individual taxa, I found that trawling had

Abstract:
The Wing Trawling System (WTS) was tested as an alternative to traditional shrimp capture methods in the Gulf. Compared to an otter trawl, this trawl was conceived to reduce bycatch, retain shrimp catch, and minimize seafloor disturbance. Through seventy-one paired tows, the WTS was assessed against a standard otter trawl. The WTS was found to reduce bycatch by 63-65% and reduce shrimp catch by 30-35%. Additionally, I measured the depth of the scars produced by both trawls and quantified the turbidity of the plumes behind them. The scars left by the WTS and the otter trawl were between 9.9 cm-

AbstractBottom trawling developed from the practice of fishing with a net or long lines, but that older style was able to be more controlled and discriminate in its catch. With bottom trawling, nets are weighted to keep them low along the seafloor and a large beam on deck spreads nets wide to increase catch. Marine biologists and environmentalists have been concerned about trawling since it began. As far back as 1376, the English parliament highlighted the destructive nature of the practice to fish populations and habitats, noting that it ‘runs so heavily and hardly over the ground when fishin

Bottom trawling, in particular, grew from a need to keep up with declining fish stocks and developed further with technological changes and increased demands, though it created ‘anger and resentment’ within the fishing communities (Bolster, 2012, p. 236).

Interference between trawl gears and subsea pipelines is an important issue. A special case called hooking, defined as the situation when the trawl gear gets “stuck” under the pipeline, should be a rarely occurring situation. In this case, however, the warp line tension could be high as its breaking strength. This may be detrimental with respect to both fishing vessel safety and pipeline integrity. This calls for a better understanding of the hooking phenomenon. The goal of this study is to develop a proper numerical model to describe the hooking event. The proposed model is based on the finit

In prawn-trawling operations, otter boards provide the horizontal force required to maintain net openings, and are typically low aspect ratio (∼0.5) flat plates operating on the seabed at high angles of attack (AOA; 35–40°). Such characteristics cause otter boards to account for up to 30% of the total trawling resistance, including that from the vessel. A recent innovation is the batwing otter board, which is designed to spread trawls with substantially less towing resistance and benthic impacts. A key design feature is the use of a sail, instead of a flat plate, as the hydrodynamic foil. The

Abstract:
Within the BMBF funded second phase of the DAM project „Ausschluss mobiler grund-berührender Fischerei (MGF) in marinen Schutzgebieten der Ostsee – Phase II (MGF-Ostsee-II)“ an experimental field study has been conducted to determine the effects of bottom trawling on the benthic ecosystem of the German coastal Baltic Sea. An area characterized with low fishing activity was selected in the Mecklenburger Bight ca. 5 km north of the town Kühlungsborn based on geo-acoustic and sedimentological criteria. In a part of this area referred to as High Impact area, high intensity trawling was simulated b

The expedition AL570 with the RV Alkor was carried out within the framework of the interdisciplinary DAM MGF-OSTSEE Project “Potential effects of closure for bottom fishing in the marine protected areas (MPAs) of the western Baltic Sea – baseline observations” funded by the Ministry of Education and Research (BMBF). Within MGF-OSTSEE a consortium of scientists from various institutions investigates how benthic ecosystems in Natura 2000 areas within the German exclusive economic zone develop after the exclusion of bottom trawling. Major goals of the project are i. the initial assessment of the

Abstract:
A short but productive cruise aboard RV William Kennedy tested various new field equipment near Halifax (port of departure and return) but also in areas that could also benefit science understanding. The GSC-A Gavia Autonomous Underwater Vehicle equipped with bathymetric, sidescan and sub-bottom profiler was successfully deployed for the first time on Scotian Shelf science targets. It surveyed three small areas: two across known benthic sponge, Vazella (Russian Hat) within a DFO-directed trawling closure area on the SE flank of Sambro Bank, bordering Emerald Basin, and one across known pockmar

Abstract:
For accurate stock assessment, survey design must consider fish behavior and ecology. Yearlings and older individuals of the commercially exploited cold-water species vendace (Coregonus albula) are found below the metalimnion through periods of thermal stratification. These stratification periods generally last for 3-4 months, from the middle of summer to early autumn. In lakes with heterogeneous distribution of depths, the habitat volume for vendace vary drastically within and across years, which affects the distribution and population densities. Variable thermal habitat volumes, with food an
