Herring - nursery grounds (Coull et al 1998) |
This data was prepared for the report 'Coull, K.A., Johnstone, R., and S.I. Rogers. 1998. Fisheries Sensitivity Maps in British Waters' which includes maps of the main spawning and nursery grounds for 14 commercially important species (cod, haddock, whiting, saithe, Norway pout, blue whiting, mackerel, herring, sprat, sandeels, plaice, lemon sole, sole and Norway lobster).
During the late 1990s, a collaborative project between the national fisheries laboratories (Cefas and the then Fisheries Research Services, Aberdeen), the UK Offshore Operator's Association (UKOOA), the Scottish Fishermen's Association (SFF) and the National Federation of Fishermen's Organisations (NFFO) produced the Fisheries Sensitivity Maps in British Waters.
The data is available from CEFAS via http://data.cefas.co.uk/#/View/149. This layer displays nursery grounds for Herring.

Demersal Fish - Spatial variation in Species Diversity of demersal fish in waters around Scotland, averaged over the period 1999 to 2008 |
The spatial variation in Species Diversity of Demersal fish in waters around Scotland, averaged over the period 1999 to 2010
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:
- Size Composition (Large Fish Indicator) (defined as the proportion of fish (by weight) in the community that is greater than 40 cm in length). The higher the value (varying between 0 and 1), the greater the proportion of large fish in the community.
- Species Richness (a count of the number of Demersal fish species recorded in any survey sample).
- Species Diversity (indices that also take account of the relative abundance of each species in the sample).
All three datasets are based on surveys carried out by ICES set up to provide fisheries independent information to support stock assessments.

Norway Pout - Modelled probability of year 0 group (restricted zoom) |
The requirement to display sensitive areas relating to the life history of commercially important fish species in British waters is well recognized. Sensitive areas have previously been described as spawning and nursery grounds. Here we consider only areas where there is evidence of aggregations of 0 group fish and/or larvae of key commercial species. 0 group fish are defined as fish in the first year of their lives. These fish sensitivity maps were originally generated to provide a spatial and temporal description of where physical damage could potentially occur to fish species at sensitive stages in essential habitats of their life cycle. Sources of damage in this context referred to seismic surveying conducted by the offshore Oil and Gas industry during their site investigations. In addition to the acoustic energy that the seismic survey activities generate, we should now add other percussive impact noises from pile driving seabed foundation pins into the seabed, such as those required for offshore renewable energy sites. The spatial location of these fish life history events and their potential interaction with offshore industries can heavily influence the planning, costs and delivery of these offshore developments. It is imperative that these maps reflect the current extent of these areas.
This layer depicted modelled probability of Norway Pout in year 0 group.

Norway Lobster (Nephrops norvegicus) - Effort of vessels landing >75% Nephrops during 2007-2012 (Count of VMS positions) |
The most valuable shellfish species (and sometimes the most valuable commercial species overall to Scotland) is the Norway lobster, Nephrops. This species is distributed in all areas where soft mud and sandy mud occurs. These areas dominate most of the firths of Scotland and extensive areas of the west coast. In more recent years a major fishery has developed at the offshore Fladen Ground in the North Sea and this is now the biggest Nephrops fishery in the world. Nephrops fisheries are prosecuted by a large fleet of generally smaller vessels using otter trawls and on the west coast there is an extensive creel fishery.
The information shown on this data layer indicates areas where effort (measured in number of Vessel monitoring system VMS pings per grid cell) to catch Nephrops takes place. Data is averaged for the period 2007-2012.

Norway Lobster (Nephrops norvegicus) - Underwater TV-assessed burrow density (average of burrows) 2007-2016 (time-aware) |
Scottish underwater TV surveys to estimate Nephrops burrow distribution and abundance, from Nephrops Functional Units of significance to Scotland. Underwater TV footage is taken at specified stations within Functional Units. The underwater camera is mounted on a towed sledge and tow duration is 10 minutes. Records of Nephrops burrows, Nephrops and other benthic fauna is recorded onto DVD for analysis and review. At each station, a custom built sledge is towed along the sea bed and all Nephrops burrow complexes are counted and used to derive density estimates. These estimates are shown in this data layer.
