Fishing - tonnage, effort and value change maps
There are 9 map layers on NMPi showing changes over the last 5 years of published statistics for:
- tonnage for demersal, pelagic and shellfish species.
- value (£) for demersal, pelagic and shellfish species
- effort (days) (by UK vessels >10m length) for demersal active (bottom trawls, dredges etc); pelagic active (pelagic trawls, purse seines etc); and passive (pots/creels, gillnets etc).
The effort data have been split by gear rather than by species. This protects commercial confidentiality and provides a more informative dataset.
Figures are derived from commercial fishing activity in Scottish seas, including UK registered fishing vessels wherever they land and non-UK vessels if landing into the UK. Data are redacted (not shown) if less than five vessels operate within an ICES statistical rectangle.
Users are recommended to zoom in to see the detail of the graph axes. For each layer, the colour of the ICES rectangle represents the data for the most recent year. Rectangles cross-hatched indicate that fishing takes but the data are disclosive (cannot be displayed for reasons of commercial confidentiality).
