Metadata: 2004 Strategic Environmental Assessment SEA5 Technical Report - Shellfish and fisheries (Northern North Sea)
Abstract:
This report is a contribution to the Strategic Environmental Assessment (SEA5) conducted by the Department of Trade and Industry (now Department of Energy and Climate Change). The SEA5 review differs from previous assessments in that the zone includes a large coastal fringe, along the whole east coast of Scotland and the Northern Isles, and contains a diverse range of habitats, from inter-tidal rocky shores and sandy beaches, to the shallow sub-littoral and deepwater mud basins offshore. These habitats support a wide range of invertebrate resources, of which six species of crustacean, four species of bivalve mollusc and two species of gastropod mollusc form the basis of a thriving shellfish fishing industry in Scotland. The landings are dominated by the Norway lobster, Nephrops norvegicus which occurs in four main areas, one of which, the Fladen ground, is in close proximity to mature oil fields. The fishery for this species in the North Sea is likely to increase, with diversion of effort from the demersal fisheries for cod and other whitefish. Much of this expansion should take place at Fladen where the stock is at present under-exploited. It is likely, however, that trawl gear used in the Norway lobster (and pink shrimp) fisheries will be required to be more selective in order to reduce the by-catch of demersal fish, especially cod, and the wastage through discarding of under-sized fish. Relevant aspects of the biology of each species are described, including habitat preference, distribution, feeding, life-cycle, reproduction and spawning. Details are given about the fishing methods used, assessments of the state of stocks, and the management regime and legislation currently used to control each fishery.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Report prepared by Colin A Chapman as part of the UK Department of Energy and Climate Change's Offshore Energy Strategic Environmental Assessment programme. Fishery landings data were available from yearly additions of Scottish Sea Fisheries Statistics and from the Aberdeen Marine Laboratory fishery statistics database. The latter information is stored with reference to ICES statistical rectangle codes. Each rectangle covers an area of seabed of approximately 30 square nautical miles. The grid of ICES statistical rectangles does not match precisely with the boundaries of the SEA5 zone, requiring a degree of compromise in selecting the most appropriate fishery data. Account was also taken of the fact that when the SEA5 boundaries were originally established, several inshore areas were excluded from oil and gas |
