  • 6 North Sea 6.1 Ecosystem Overview 6.1.1 Ecosystem Components
    6 North Sea 6.1 Ecosystem overview 6.1.1 Ecosystem components Seabed topography and substrates The topography of the North Sea can be broadly described as having a shallow (<50 m) southeastern part, which is sharply separated by the Dogger Bank from a much deeper (50–100 m) central part that runs north along the British coast. The central northern part of the shelf gradually slopes down to 200 m before reaching the shelf edge. Another main feature is the Norwegian Trench running east along the Norwegian coast into the Skagerrak with depths up to 500 m. Further to the east, the Norwegian Trench ends abruptly, and the Kattegat is of depths similar to the main part of the North Sea (Figure 6.1.1). The substrates are dominated by sands in the southern and coastal regions and fine muds in deeper and more central parts (Figure 6.1.2). Sands become generally coarser to the east and west, with patches of gravel and stones existing as well. In the shallow southern part, concentrations of boulders may be found locally, originating from transport by glaciers during the ice ages. This specific hard-bottom habitat has become scarcer, because boulders caught in beam trawls are often brought ashore. The area around, and to the west of the Orkney/Shetland archipelago is dominated by coarse sand and gravel. The deep areas of the Norwegian Trench are covered with extensive layers of fine muds, while some of the slopes have rocky bottoms. Several underwater canyons extend further towards the coasts of Norway and Sweden.

The Royal Society of Edinburgh (RSE) is Scotland’s National Academy. Born out of the intellectual ferment of the Scottish Enlightenment, the RSE was founded in 1783 by Royal Charter for the “advancement of learning and useful knowledge”. As a wholly independent, non-party-political body with charitable status, the RSE is a forum for informed debate on issues of national and international importance and draws upon the expertise of its multidisciplinary Fellowship of men and women of international standing, to provide independent, expert advice to key decision-making bodies, including Government and Parliament. The multidisciplinary membership of the RSE makes it distinct amongst learned Societies in Great Britain and its peer-elected Fellowship encompasses excellence in the Sciences, Arts, Humanities, the Professions, Industry and Commerce. The Royal Society of Edinburgh is committed to the future of Scotland’s social, economic and cultural well-being. RSE Inquiry into The Future of the Scottish Fishing Industry i Foreword The fishing industry is of much greater social, economic and cultural importance to Scotland than to the rest of the UK. Scotland has just under 8.6 percent of the UK population but lands at its ports over 60 percent of the total UK catch of fish.

Capperucci 1 , Svenja Papenmeier 3 and Alexander Bartholomä 1 1 Senckenberg am Meer, Department for Marine Research, Südstrand 40, 26382 Wilhelmshaven, Germany; [email protected] (P.H.); [email protected] (R.M.C.); [email protected] (A.B.) 2 Department of Geosciences, University of Bremen, Klagenfurter Straße 4, 28359 Bremen, Germany 3 Leibniz Institute for Baltic Sea Research Warnemünde, Seestraße 15, 18119 Rostock, Germany; [email protected] * Correspondence: [email protected] Received: 25 September 2020; Accepted: 21 October 2020; Published: 25 October 2020 Abstract: The anthropogenic impact in the German Exclusive Economic Zone (EEZ) is high due to the presence of manifold industries (e.g., wind farms, shipping, and fishery). Therefore, it is of great importance to evaluate the different impacts of such industries, in order to enable reasonable and sustainable decisions on environmental issues (e.g., nature conservation). Bottom trawling has a significant impact on benthic habitats worldwide. Fishing gear penetrates the seabed and the resulting furrows temporarily remain in the sediment known as trawl marks (TM), which can be recognized in the acoustic signal of side-scan sonars (SSS) and multibeam echo sounders (MBES). However, extensive mapping and precise descriptions of TM from commercial fisheries at far offshore fishing grounds in the German EEZ are not available. To get an insight into the spatial patterns and characteristics of TM, approximately 4800 km2 of high-resolution (1 m) SSS data from three different study sites in the German EEZ were analyzed for changes in TM density as well as for the geometry of individual TM.

  • Investigations Into Closed Area Management of the North Sea Cod
    The Centre for Environment, Fisheries & Aquaculture Science Investigations into closed area management of the North Sea cod for Department for Environment, Food and Rural Affairs Defra Reference: SFCD15 CEFAS Contract report C2465 INVESTIGATIONS INTO CLOSED AREA MANAGEMENT OF THE NORTH SEA COD Cefas Reference C2465 Defra reference SFCD ref 15 Closed areas have been proposed as one of a range of potential management approaches that could be applied to control the exploitation rate of the North Sea cod stock. However, although theoretical studies of the potential effects of closed area are numerous, they are of limited use for providing practical management advice, because they are not case-specific. The aim of this project was to bring together fishers’ knowledge of current and potential future North Sea fleet fishing activity with research on the spatial movement of fleets, cod population biology and the impact of fishing on benthic biodiversity, in order to provide practical advice on the impact of closed area management in the North Sea. Research is required to aid the provision of advice on the potential impact of closed area management on cod population dynamics, habitat diversity and the economics of the North Sea fleets. Examples of closed area management regimes for the North Sea cod were simulated, and the impact on the catches of cod, mixed gadoids and benthic productivity and diversity was evaluated. Funding and the time available for the study was limited, so the work examined three example scenarios: two evaluating the impact of large, broad-scale, North Sea closures, and at a more detailed scale, the effect of a local closure on the cod fishery off the northeast coast of England.
