Long-term morphological and sedimentological changes caused by bottom trawling on the northern Catalan continental shelf (NW Mediterranean)

open access: yesFrontiers in Marine Science, 2023
Bottom trawling is a fishing method that involves towing of nets along the seafloor to catch demersal species. The dragging of trawling gears along the seafloor results in scraping and ploughing of the surficial sediments, leading to the formation of ...

Impacts of bycatch from beach seining: a case study of a shrimp fishery in Brazil [PDF]

open access: yesAnais da Academia Brasileira de Ciências
It is commonly assumed that beach seining (BS) is more sustainable than bottom trawling because it involves non-motorized operations and limited fishing power. However, no scientific evidence supports this assumption.

Calibration of bottom trawls for northern shrimp [PDF]

open access: yesICES Journal of Marine Science, 2008
Abstract Kingsley, M. C. S., Wieland, K., Bergström, B., and Rosing, M. 2008. Calibration of bottom trawls for northern shrimp. – ICES Journal of Marine Science, 65: 873–881. The Skjervøy 3000 trawl used since 1988 in the West Greenland bottom-trawl survey has been replaced by a Cosmos 2000. To be able to compare old data on the northern

Out of Sight, But Within Reach: A Global History of Bottom-Trawled Deep-Sea Fisheries From >400 m Depth

open access: yesFrontiers in Marine Science, 2018
Deep-sea fish species are targeted globally by bottom trawling. The species captured are often characterized by longevity, low fecundity and slow growth making them vulnerable to overfishing.

An assessment of discarded catches from the bottom pair trawling fishery in southern Brazil

open access: yesMarine and Fishery Sciences, 2021
Onboard discards of a fraction of the catch can be considered one of the main issues related to bottom trawling fisheries. The magnitude and composition of the discards still need to be better understood.

A dataset from bottom trawl survey around Taiwan

open access: yesZooKeys, 2012
Bottom trawl fishery is one of the most important coastal fisheries in Taiwan both in production and economic values. However, its annual production started to decline due to overfishing since the 1980s. Its bycatch problem also damages the fishery resource seriously.

Density Dependent Catchability In Bottom Trawl Surveys

open access: yes, 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.

Trawling-Induced Sedimentary Dynamics in Submarine Canyons of the Gulf of Palermo (SW Mediterranean Sea)

open access: yesJournal of Marine Science and Engineering
Bottom trawling in submarine canyons can affect their sedimentary dynamics, but studies addressing this topic are still scarce. In the Gulf of Palermo (NW Sicily, SW Mediterranean Sea), bottom trawling occurs on the continental slope, but principally ...

DEVELOPMENT AND TESTING OF ALGORITHM FOR CALCULATION OF OPERATING PARAMETERS OF TRAWLING SYSTEMS

open access: yesИзвестия ТИНРО, 2019
Numerical model of trawling system is developed on the base of equilibrium principle, using F.I. Baranov’s scheme of its power and geometric parameters interdependence.

Deep-Sea Mega-Epibenthic Assemblages from the SW Portuguese Margin (NE Atlantic) Subjected to Bottom-Trawling Fisheries

open access: yesFrontiers in Marine Science, 2017
Bottom-trawling fisheries are a common threat to the health of continental margins worldwide. Together with numerous environmental and biological processes, physical disturbance induced by trawlers can largely shape the benthic habitats and their ...
