Grey seals (Halichoerus grypus) are present around the coast of Scotland in internationally import numbers. They breed on wave-exposed rocky coasts, sometimes on sand or shingle beaches at the foot of cliffs, often on relatively remote islands, with large groups of pregnant females returning to traditional breeding sites in the autumn. This data shows the breeding colonies currently listed with Sea Mammal Research Unit (SMRU).
Nephrops distribution is limited by the extent of suitable muddy sediment in which animals construct burrows. Nephrops are assessed across Europe as individual stocks in 34 functional units (FUs). This data combines the ICES functional units (based on ICES statistical rectangles), combined with the actual extent of the muddy sediment, in Scottish & adjacent waters, derived from sediment and VMS data.
The spatial variation in Species Richness of demersal fish in waters around Scotland, averaged over the period 1999 to 2009.
This dataset is part of the larger Spatial Variation of Demersal Fish in Waters Around Scotland Dataset, which includes three layers that show the spatial variation of Demersal fish (generally living on or near the seabed) in waters around Scotland (averaged over the period 1999 to 2008) for:
All three datasets are based on surveys carried out by ICES set up to provide fisheries independent information to support stock assessments.
