One of the most widespread yet manageable pressures imposed on the seabed is that resulting from disturbance of the substrate by towed demersal fishing gear (bottom fishing and dredging). Demersal fishing gears are deployed on every continental shelf in the world and, in UK waters, the footprint of fishing is estimated to account for over 99% of the known footprint of all human pressures on the seabed. It is, therefore, essential that current and future management of fishing activities are based on an improved scientific rationale in order to improve the long-term sustainability of this activity. While the impacts of demersal fishing on the biological characteristics of the seabed have been well-studied, the approaches have tended to focus on assessing...

Impact of technological creep on fishing effort and fishing mortality, for a selection of European fleets ArchiMer
Marchal, Paul; Andersen, Bo; Caillart, B.; Eigaard, Ole; Guyader, Olivier; Hovgaard, Holger; Iriondo, Ane; Le Fur, Fanny; Sacchi, Jacques; Santurtun, Marina.
Face-to-face interviews were conducted to identify the main changes in gear and vessel technology that may have improved the fishing efficiency of a number of French, Danish, and Basque fleets over the past few decades. Important changes include the gradual appearance of twin trawls (Danish and French trawlers) and trammel-nets (French gillnetters), and the increased polyvalence of Basque bottom trawlers. The results suggest that fishing effort descriptors that are not traditionally measured (gear type, groundrope type, length of net used per day, headline length, crew size, number of winch or net drums) may have a substantial impact on catch rates. Adjusting fishing effort using such descriptors may generally improve the relationship between fishing...

Report on assessing trawling impact in regional seas ArchiMer
Nielsen, J. Rasmus; Bastardie, Francois; Buhl-mortensen, Lene; Eigaard, Ole; Gümüs, Aysun; Hintzen, Niels T.; Kavadas, Stefanos; Laffargue, Pascal; Mehault, Sonia; Notti, Emilio; Papadoupoulou, Nadia; Polet, Hans; Reid, David; Rijnsdorp, Adriaan D.; Rochet, Marie-joelle; Robert, Alexandre; Sala, Antonello; Smith, Chris; Virgili, Massimo; Zengin, Mustafa.
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...
