Increasing sediment accumulation rates in La Fonera (Palamós) submarine canyon axis and their relationship with bottom trawling activities
(American Geophysical Union, 2015-10)
Previous studies conducted in La Fonera (Palamós) submarine canyon (NW Mediterranean) found that trawling activities along the canyon flanks cause resuspension and transport of sediments toward the canyon axis. 210Pb ...
Global analysis of depletion and recovery of seabed biota after bottom trawling disturbance
(National Academy of Sciences, 2017-08)
Bottom trawling is the most widespread human activity affecting seabed habitats. Here, we collate all available data for experimental and comparative studies of trawling impacts on whole communities of seabed macroinvertebrates ...
Chronic and intensive bottom trawling impairs deep-sea biodiversity and ecosystem functioning
(National Academy of Sciences, 2014-04)
Bottom trawling has many impacts on marine ecosystems, including seafood stock impoverishment, benthos mortality, and sediment resuspension. Historical records of this fishing practice date back to the mid-1300s. Trawling ...
Estimating codend size selectivity of bottom trawlnet in Chilean hake (Merluccius gayi gayi) fishery
(Escuela de Ciencias del Mar <BR>Pontificia Universidad Católica de Valparaíso, 2005)
Marine mammal bycatch by the industrial bottom trawl fishery at the Río de la Plata Estuary and the adjacent Atlantic Ocean.
(Pontificia Universidad Católica de Valparaiso, 2019)
Fisheries interactions with non-target marine vertebrates are a worldwide problem. The impact of coastal bottom trawl fisheries on marine mammals has never been evaluated before in the Río de la Plata Estuary and the ...
Marine mammal bycatch by the industrial bottom trawl fishery at the Río de la Plata Estuary and the adjacent Atlantic Ocean
(Pontificia Universidad Católica de Valparaíso, 2019-01)
Fisheries interactions with non-target marine vertebrates are a worldwide problem. The impact of coastal bottom trawl fisheries on marine mammals has never been evaluated before in the Río de la Plata Estuary and the ...
Gastropods and bivalves taken as by-catch in the deep-water shrimp trawl-fishery along the Pacific coast of Costa Rica, Central America
(2017)
Deep-water habitats are among the least studied but most vulnerable environments. By-catch data from deep-water fisheries in Latin America are limited, and detailed reports on associated molluscs are scarce. This study ...
Investigating the effects of mobile bottom fishing on benthic biota: a systematic review protocol
(BioMed Central, 2014-11-25)
Background: Mobile bottom fishing, such as trawling and dredging, is the most widespread direct human impact on marine benthic systems. Knowledge of the impacts of different gear types on different habitats, the species ...
Avaliação da composição do lixo marinho oriundo da pesca artesanal de arrasto de fundo do litoral do Paraná
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Química e Biologia, 2012-12-06)
This paper has the objective to evaluate, quantify and distinguish the solid debris collected by the trawling in Matinhos and Shangri-lá. The samples collected between October 2009 and June 2011 by the REBIMAR project were ...
Estimating the sustainability of towed fishing-gear impacts on seabed habitats: a simple quantitative risk assessment method applicable to data-limited fisheries
(British Ecological Society, 2016-11)
Impacts of bottom fishing, particularly trawling and dredging, on seabed (benthic) habitats are commonly per-ceived to pose serious environmental risks. Quantitative ecological risk assessment can be used to evaluate ...
