Effets combinés des facteurs naturels et anthropiques sur les communautés d'invertébrés benthiques des vasières à langoustines (Nephrops Norvegicus) du golfe de Gascogne ArchiMer
Robert, Alexandre.
Bottom trawling is a widespread fishing activity that covers most of the North-European continental shelves. This activity is likely to alter the benthic habitats, the structure and biodiversity of benthic communities as well as the ecosystem functioning. However, bottom trawling effects vary according to the habitats and, specifically according to the magnitude of the natural sources of disruptions. Consequently, it is difficult to predict the effects of the fishing activity. So, a specific investigation has to be conducted in each fishery in order to characterize the effect of bottom trawling. The Bay of Biscay (BoB) is fished for Norway lobsters and hake. Bottom trawling is one of the most important fishing activities, both economically and regarding to...

Baltic Sea Benthic ecosystem impacts from demersal fishery in the western Baltic is assumed to come mainly from Nephrops trawling in the central and southern Kattegat, mussel dredging in the Belt Sea, and mixed cod trawling in the western Baltic Sea.These fisheries both impact the seabed, as well as produce substantial amounts of discards. The western Baltic Sea offer a unique opportunity to analyse the benthic effects of fishingthanks to the closure of Øresund to towed gears since the 1920s, and the introduction of the Kattegat MPA in2009 (including cod closure) and the western Baltic Sea Natura-2000 areas. Furthermore an extensive benthic nationalmonitoring and data collection effort has taken place in the area over a number of years, which can be usedto...
